Hi Jim, not wishing to burst your bubble, but the worst thing you can do for PVC pipes is to have rocks under/over with direct contact to the pipe. I am a retired backhoe operator with 40 years of experience working for the American Army, Directorate of Publoc Works in Germany. From my time with the DPW I must have excavated over a hundred broken PVC pipes and I can honestly say the breaks were all caused by rocks having contact with the pipe. Just imagine you are a buried PVC pipe and there is a rock pushing against your side. The rest of the backfilled ground is loose soil getting ready to subside and compact, with each rainfall. The normal (small particle) soil will equally compact around the pipe, but any rocks touching the pipe will remain the same size and eventually the subsiding soil will üush the rock(s) to the point that a hole will appear. Rule of thumb when burying PVC pipes is to have six inches of sand below and six inches of sand above the pipe, before backfilling natural products. I hope not, but I can see you have a lot of problems with this in the future. Sorry about the bad news, Regards, John
@scrumpyman51 and what's worse is they perforated the pipes which is begging for water infiltration by default. That water will pool into the pipe during monsoon
Seems like every French drain in existence would be in peril. Of course I wouldn't want water in there either. Not sure of the logic using French drain tube.
@@EarthCreature. So... the holes in the pipes raised my eyebrow as well. However, the holes are on the bottom - they just demonstrated turning the entire pipe over in this episode - so the only way there's pooling is if the water table in the desert rises above the bottom of the pipe. I don't suspect that's likely, but could be wrong. I think the holes are there to get rid of any condensation that might occur? I know there's gravel underneath (which, as scrumpyman noted might be its own issue) so water in the pipe would quickly drain away. I dunno, that's my take on it.
Yeah I was honestly thinking they should have laid a layer of sand down put the pipes on top of that layer of sand and then cover it up with sand and then back filled everything.
@scrumpyman51 Hey John; when your company business did the back hoeing (which included PVC pipes for massive underground projects), did you ever see black tar (the same that is used to protect basement walls, etc)used around the pipe connections and the pipes itself to secure an additional layer of protection? Some of our contractors; where I live, have done this to add an extra layer of protection to the pipe. We have all sorts of weather conditions (not only neg 50 degrees in winter but also heat in triple digits 106-120’s in summer too), our rampages include potential ripples in the ground from unknown earthquakes, changes in the terrain which can open the ground from crazy gas pockets, ungodly amounts of gophers that eat through everything; where those holes are large enough to drop a child into the earth and lately we’ve even had swams of bees in the ground!
Way back in 1981 I built a home for a couple of fellow hippies in Western Ma. We designed our own heat/cooling system with nothing but a ton of PVC pipes buried 60” below grade. Laid over (soft sand only ) rocks can and will bust up the pipes over time. Laid in sand they will last forever. 4” sch40 pvc laid every 24” with three layers. All tied together with a HO FAN running to pull fresh air into the pipes. At that depth the ground is @ 52-55 degrees all year round. So in the summer a small HO fan will cool your entire house. ( you must install standard air ducting in the house) the pvc piping will drop @55degree air into your furnace and heating it 15 degrees doesn’t take much energy at all.
That was a very long time ago. The current owners are the same couple I built the house for. A few years ago I ran into them and I was thrilled to hear that my invention worked awesome and continues to heat and cool their 3209 sq ft home for almost nothing. He figured it costs him around 97bucks a year to run the fans.
I’m so happy it worked for them. My formula is :
For every 100 sq ft. of living space you need @40’ of running pipe.
Works like a charm. Thank you Mother Nature. ✌️❤️🇺🇸
Harvesting cool air from underground with access to the outside air would provide lower temperatures needed to improve efficiencies for electrical powered atmospheric water generators (AWG) devices that harvest the water from humidity by lowering the temperature to necessary condensation or dew point. These AWG devices filter the water for drinking but usually require one kilowatt per gallon and humidity levels near 50% or more is preferred. There has been reports about new AWG devices that can produce fresh water at much lower humidity levels as low as 5% is interesting to google.
HO fan? Heat pump fan? I’ve been thinking about this solution for over 30 years wondering if whole house fan would work for old farmhouse. You’re the first person who has said how much piping per sf. Thanks so much for sharing.
@@so.many.projects
For a typical SHCS (subterranean heating and cooling system) you would install 1.3ft of 4" tubing per sq ft of floor area. 100sq ft floor area = 130ft of tubing.
That was MA. This is AZ. Our ground temps are much warmer. They will be lucky to get 80° out of this. Can't wait to be proven wrong.
@@beautanicalgardens6353
Anywhere on planet earth the ground temperature remains constant between 53.5 degrees and 54.2. It is the same temperature below 50”
It works trust me.
Curious.......have you tested for radon gas in your area? I'd be concerned of it being pumped into the house through the tubes.
Jim tested for Radon before he ever got started and published a video with the results
Love watching. Been following you for a long time. I do have one question on the earth tubes. How will you controll or keep the mold spurs from flying into your home? I know you have holes to drain the water out. However overtime won't mold still build.
As a long married couple.. I have often found that my hubby will be discussing a problem he's trying to solve, and my mind will suggest a simple solution.. Because our minds think differently at times.. And Visaversa.. sometimes, he will come up with an idea!!! "I could have had a V8" moment.
You and your wife are hard working couple. Your underground cooling system is a great idea, however you may have a flaw. Shouldn’t you have intake vent to allow more air to circulate through the pipes. Just a thought before you go to far…
I was excited to find your channel, very interested in your earth tube AC. However I just watched 20m.of burying pipes by hand - which was not very interesting.
Dude borrow your friends tractor that's too much work!
Super dangerous working in a trench like that without supported walls, lucky it didn't collapse on you.
It's the soil content on their property. It's a good amount of clay that holds up well... Until it gets wet.
Couldn't have walls like back in Florida, they would be digging your body out. Hard clay is much safer than Florida sand. Why are you not putting sand as a cushion down, and putting sharp rocks, running around the pipe? I assumed that your soil is high in clay. Or you probably couldn't build with it too well. Good luck on your learning experience.
Wow two years ago for lluvia being a big part of your lives..dang time does fly when your having fun huh....So happy for you all out there she is a gem for a dog without a doubt and I was glad to see she knew not to try the loose dirt into the trenches good girl...Happy Anniversary to such a great dog and addition to your homestead....
Jim, You are really doing extremely hard physical work! By the end of the project, you'll have arms like The Rock 😂
Your both pretty amazing folks. I love how Jess cares for the birds, wildlife and those precious plants.
Always happy to watch your new uploads and looking forward to your next. Be safe and wishing positivity and blessings from northern Indiana
with closed system no Bugs, Snakes, Critters, Worms of MOLD could enter the system / I think the holes are a big mistake in the design
Happy Anniversary Lluvia. Hope you have a special day today.🍗🦴
not to be hateful but you would be way ahead to get a used compact tractor for 3 or 4 thousand and not keep killing yourself.
Its crazy watching this it feels like I'm missing key info! Why the holes drilled into the pipe and not using a landscape sleve to keep dirt from leeching inside the pipe? Also why not assemble pipe sections above ground seems like you'd have better access and be faster? Why not encase pipe in gravel with only only putting a few inches on the bottom you'll stil get dirt leeching into the pipe? Also if your just pulling air through the pipe that seems like a pretty small diameter even using multiple pipes? Your viewers have questions!! LOL!
Exactly what I was thinking - why have holes in the pipe and nothing stopping the dirt going in?
The holes allow for draining of condensation that builds in a system like this. I also wonder however on why not using landscape barrier fabric to protect the gravel and pipe from dirt infiltration. Great to watch the work. Amazing stamina to shovel all that dirt back in.
Yeah I've been researching earth tube home ventilation systems for years. This is the first one I've seen with holes in it. Seems like you have just built a French drain in the desert .
@@roberthaney8035 my thoughts exactly. It’s monsoon season in Ai right now and when those trenches fill with water so will the tubes. The house will smell like dirt.
@@grantlouw3182😊😊
I am amazed by the amount of physical work you are doing on those trenches!
Curious why you didn't buy sewer pipe with the holes already in it?
@bigunone because holes work both ways. They let stuff in, too, so you don't want them on the top and sides.
Shocking the amount of work you spend time doing by hand. I couldnt even fathom not having a small Craftsman riding lawn mower with a hitch to haul a small trailer or even a small dump cart. Twice as many loads it takes when doing some of this stuff by hand, Not to mention the amount of money you probably spend on Ibuprofen. I mean a used Craftsman riding mower is like a few hundred dollars.
You and Jess never cease to amaze me! You are such hard workers, it’s wonderful to see your vision develop! 👍🏼👍🏼👍🏼👍🏼
Happy anniversary to Lluvia. Awesome progress
Hello sweethearts, Happy anniversary to Lluvia🎉🎉. May God continue blessing you. And many, many years of life with Her. ❤❤
Fascinated by this project, but a question. What is the purpose of the 1/2" holes every 6", and what keeps the dirt covering the pipe from migrating inside the pipe.
Drain holes to drain the excess moisture, they will be facing down, and the holes allow earthworms to travel rapidly..
@@everettplummer9725worm subway!
Allows condensation that firms in the pipe walls to drain. Otherwise you'd have serious problems with mold and water build up in pipes until it shut off air flow.
I'm just glad that - with editing delay - you guys probably have already figured all this out and are looking forward to your new air-conditioned addition.😂
The large rocks might crush your pipe as you backfill. The pressure that would normally be evenly distributed will be concentrated at the rocks. The rocks above will be like splitter mauls with the force of all of the dirt above and the rocks below will be like sharp anvils that the pipe will be pressed against.
I was thinking the same thing. For sure not good to have those rocks next to the pipe.
aren't the rocks too heavy on the pipes? what if you have a problem and have to dig up your work, just wondering, please be careful with your back, that's a lot of stress
Amazing progress, glad the excavator worked on the third trench without waiting too long.And happy anniversary Lluvia!
Is it possible to use the neighbour's tractor to fill up the trenches?
Why not put polythene on top of the pipes to stop dust getting in? Why not use the excavator to push the dirt back in?
It's amazing isn't it ??? How a "trench" can be "beautiful" !!! When it's done, of course, by a skilled, experienced, professional !!! Even with all the force they are working with through the hydraulics, the good operators can feel when they are hitting a "plastic" pipe if they are aware there might be some where they are working.
@ 19:40 so right there is where you do a full one eighty and run another pipe straight back to house to complete the loop / then a simple computer fan in one end would push air out to where sitting now and the air could cool more as it made the loop back to the house / this design is making me nuts watching it be built / if spending money to dig a trench get as much pipe contacting the soil as possible
A computer fan wont provide enough pressure to overcome the frictional loss of a long tube with a 180 degree turn. The higher the frictional loss, the lower the cfm.
Don't you have a neighbor with a tractor and bucket????
Can you explain how the ac air tube works?
you are pulling desert heat cooling it, or other words making a garble tunnel, why not pull out air of the house cool it and keep moving, you know like real air works? i mean they even do the same in green houses. you just have tie the ends together.
This type of setup works quite well. Check out citrus in Nebraska on here. The hot air comes in cools down underground and then comes into the house cool. I'm not sure the depths but if at the proper depth the ground should be give or take 60°f.
@@farmerjhemp but what if pulled in the air from the house cools off as it comes back in? the air in the house is cooler so it comes back cooler, and you get full circulation as its always moving?
@@diegojines-us9pc the air is generally always moving with this also but it's always fresh air. The heat at the peak of their house will cause a convection drawing the cool air from the far end of the tube. This type of system works well passive. It's simple the house is always going to be warmer than underground.... I think with a recirculating you generally would need a big fan running for to operate well.
Not sure I get it, I've watched many Earthship builds with cooling tubes and they all have large 16 or 20, maybe 24 inch tubes, how much air can you move through a 4 inch tube?
Not nearly enough, IMO. I initially thought water was going to run through these, though thinking a smaller diameter pipe might be more efficient, until holes started being drilled in the pipes. Are the holes are to allow condensation to drain out? IDK. I'm really not sure what the game plan is here. I really hope this works out for them, but am skeptical.
@@waynegnarlie1 Ya I seen that too in the last video and I'm not sure that system of holes is correct either. Earthship's tubes are all above grade running through a berm so water can drain away easily but here it's trapped under the pipe which may lead to mold effecting air quality. I hope it works out too, that's a lot of work for an untested application....maybe I'm wrong but I've never seen anything like this.
Not much!
One 12” pipe has the same end area as three 4” pipes. With only one trench needed. And don’t weaken it by drilling holes and stacking rocks on it, and letting moisture and the earth smell in.
@@freddymax5256a 12” pipe is 113 sq inches.
A 4” pipe is 12.56 sq inches
I think your math is a little off
As a fellow homesteader i love this channel
You should affix a snow plow, or something similar(diy) to your vehicle, and push these giant piles back in!!!
Borrow neighborhood tractor like before, hopefully
A few decades ago, the Brazilian government gave many of the poor their own piece of land. They built these underground tubes in order to cool the inside of their houses. I was exploring giant lava tubes in California. We walked about 1 mile underground to the end of the tube. There was an opening through some rocks. We climbed up about 10’ feet and out of the lava tube. It was 95 that day. Once we were out we could feel dry, cold air blasting out of that hole! It was AC cold on turbo fan setting. Amazing! I immediately started telling everyone what I read about the Brazilians doing this. We hiked on and came back there to cool off again before we left. I could not believe how well that works. Everyone should be doing this! It’s so cheap and works year round. The air will be warmer in winter than outside. It sounds too simple to be true but it’s absolutely true. These two are very, very smart people to do this. Well done!
As long as you are not pulling air out quicker than what its going in, remember in the Lava Tube you had moisture in the air, in his pipe system you dont, or better not have because that can cause medical issues again, moisture and airflow is the key, thats why I would prefer to have a homemade Evaporation System, which can be off grid usually a low voltage pump and fan hooked up to a small solar panel, you could make one for a couple hundred dollars, another thing is what lots of new off grid people living in deserts dont seem to understand is keeping the sun off the roof alone brings down the temperature inside a dwelling, in some parts people use to grow vines over their houses, but you can also do that by using Sun Shade Mesh, another cheap item you can use to regulate the internal temperatures is the use of Bubble Rap, especially on large glassed areas, as it was originally invented as a insulator
There's a famous utube video about Nebraska peaches citrus in winter--retired postal worker did this long ago, has huge greenhouses with fruiting trees when it's freezing and snowbound outside. The AZ earthships all use cooling tubes now. Lots of approaches, different ways to use them on utube.
Just a point
Rounded shovel. Is digging shovel
Square shovel. Is. Grading shovel
The system you are installing is amazing at how cool they make your home.
Happy Birthday Lluvia!!. I hope you get treats for your special day❤💙🐕🎁
Anniversary, not birthday. I wonder when she was actually born. She is so sweet.
barrow a tractor thats crazy trying to do that by hand
Love you guys, but really?? This is going to take a year to hand shovel all that dirt. Get the machine back!!!!
A board on the front of a vehicle to push the dirt in.
he just needed to add a little dirt to act as a cushion when the tractor pushes it in
Being in construction for many years, I worked on many pipe runs. We know that we are never to put rocks around a buried pipe. The pressure of the earth as it naturally compacts will cause rocks to crush the pipe.
Typically place sand around before backfill with rock and soil
@allegannews9256 no, not sand, 3/4" rock gravel. Rocks will sink through sand, and contact the pipe. Gravel will stop migration.
100% right. I also learnt not to put stones nearby burried pipes. Only sand and the gravel. Those pipes might break in a few years. @OSRL Did you not do any research?
I would definitely backfill pipe with sand or washed pea gravel just to cover pipe then whatever you dig out
@youdandee1 A rock, just like a gold nugget will keep sinking through sand, until it reaches a hard surface. Gravity does that. Then soil compaction takes over, as you may have filled a hole and stomped on it, only to come back in a few weeks to find an indentation in the ground. That compaction coupled with gravity will use the rock to crush the pipe.
This isn't my theory, this is proven fact derived from lessons learned over the years.
Any good contractor knows to surround the pipe with gravel, then backfill with natural soil.
I realize this is too late. But, for the future... 1:that pipe is available with the holes already in it. 2: the primer is pointless unless you put it on long enough and wet enough to actually soften the surfaces of the nipple and socket being cemented. 3: after having layed literally miles of pvc, anywhere from 1/2" to 15" I've Never had to hand backfill any of it. You made an outrageous amount of extra work for yourself.
4: that plastic pipe is very durable and flexible. You can assemble (glue) all of it together up on the level ground, then lay it down in afterwards. 5: please explain why you don't make a big loop instead of two separate pipes pulling from the far end. Wouldn't it be better to pull already cooler (in the summer) are from your home, circulate it out, through the tunes and back into the home with a small duct fan? Like a central air Inan average home? You could use this to filter the air too...
Kepp up the videos. I love watching.
Where were all these experts when you started laying the pipe ... a while ago?
@@GM-cq6ez
Its usually too late if you`ve started laying the pipe
Happy Anniversary Lluvi, you have two great parents!🤗🍗🍖
Am I missing something? Is there something wrong with the dome you have already built? Why are you not living in it, or at least concentrating your efforts on finishing it? Could you live in it. There are heaps of channels here on TH-cam where people are living in far from complete renovation or building projects.
Im surprised you dont get a skid steer! So useful on your lifestyle
I would think a tractor with three point linkage fitted with a front loader would be a great asset. I have a small Kubota with no loader but implements on rear certainly saved my back numerous times, though a loader would be great. Hard yakka in the heat, just take care of yourselves and stay hydrated. Great effort.
you guys are awsome!! btw its a bit easier on your back if you shovel the other direction, learned this painfully, if your left hand is forward, throw to the left.
Ok When doing this job you need a silt sock over the pipe and under and over the stone. This system will fail because you did not build it right. When the pipe fill with dirt it will stop working. Why did you not use a silt cloth over the stone?
In hindsight maybe you should have made a earthship house with the air tubes running under the house.
Time for a tractor with a push bucket. Surely one of your neighbors has a tractor.
Literally True Grit! Hey you need a tractor to back fill to save your back. Thanks for mentioning it.
What ever happened to cushioning the back fill? In Canada we can use white foam directly on the schedule 40/80 then place the backfill on it gently - the added bonus is the thermal barrier... I would use 4 " white foam.
I hope you stop filling over the pipes. The holes you drill in the pipes are going to fill up with dirt. And you will not get any air throw the pipes.
The guy could at least educated himself by watching Elise a few TH-cam videos on how to do it right.. all that work what an absolute waste
There’s another way, buy 4 1X300 ‘ irrigation poly pipe coils and create a circulating loop through an H2O coil and circulate the air on low speed. This can be effective in humid environments and the piping is inexpensive compared to an earth tube. If you bring this to a manifold along with some DIY solar hot water panels you can both heat and cool from the same system.
@13:00 I would have lay'd all the pipes for the trench next to each other in a group, marked 1 and drilled them all based on the mark on the first, surely this would be a bit quicker? is there a reason you did them this way, or is this something you can improve on for the next trench?
I’m really excited to watch this project. Thanks OSRL!
@ 12:25 why the holes ?? they only allow water in ( closed system so much better ) but you can still fix one mistake and connect the two forty fives that will stick up out in the desert and make a closed loop once the house is connected, air out of house through tubes and loop back through to house so as not to cool any outside air, just keep re-cooling the same air
where I live , the wind is generally blowing from same direction each day with little variation .Did you lay the pipe with that in mind or does it matter to you ?
Hi Superman Jim, you're doing amazing work. Don't wear yourself out, please. You have a Type A personality. Love your sunny disposition. Congratulations to Lluvia and yourselves to have crossed paths 2 years ago, in the middle of the year. Do you know her actual birthday? Wishing y'all much happiness to come.
I'm curious to know if those would fill up with water and debris? and do y'all not have radon in your area no concerns about radon leeching?
We're not concerned with the radon.
I have seeen where people use a torch ( or heat gun) to heat the pipe and strech it out and put a piece of pipe in it to make a coupler some what like factory pipe. Some do this on water supply pipes. This would save a lot of money where you could use short pieces of pipe. Keep up the good work.
I may have missed it but with the holes in the tubes isn't this a radon collector? Hate to be a Debbie downer but will there be a heat exchanger for the air in the tubes?
Thank goodness u spun the pipe so that the holes are facing down... I was about to freak out lol! The purpose is to let the condensation of moisture drain yall. Great thing to do, peace
Yes, I notice the holes up too and was also worried. Glad he changed it.
When one has no experience, everyday can be a learning experience. Never having done something before it should be approached with caution. Luckily there's enough people on here that have the experience and knowledge that they can share it with others. Just because you believe something all your life doesn't make it true. Always keep an open mind.
AHHHAH, We love you guys. You are doing such a great job and luv, you seem sooo much healthier....at peace and happy. My son Ronin the 10yo has Aspbergers and I get it. Would be wonderful if you mentioned him in your next video somehow. Ronin from Wilberfore OHIO. He had questions about how this cooling system works ♡ Ty. My 7yo son Kade loves your getting dirty part lol
I can see this aint gonna last very long. living off grid is rough.
So the pipes fill up with dirt?
Tunnels of Fun and almost Done.
Congrats to Lluvia !!! And I cannot wait until your cooling system is complete so you can show us how it works!
PVC has pretty low thermal conductivity. Any metal pipe or tubing would have given you a higher efficiency.
Yes, but earth has even lower thermal conductivity. It’s mostly the dirt around the pipe that will limit the heat flow. That’s why you need such a long run.
That's a lot of work!!!
Great job 👍
Your longest day and our shortest. Great work guys.
also the gravel around the pipe defeats the purpose as you want as much of the pipe as possible to contact the cool soil / sand would have been a much better choice as it would contact the pipe more closely
Heat moves mainly via conduction, convection and radiation in these systems but there are other modes. Densely packing sand around the tube will provide mainly conductive heat transfer which effectively slows down the rate at which heat can move away from the tube. If the sand next to the tube wall heats up, the temperature differential driving your heat transfer will reduce. The air spaces in gravel move heat mainly by convection and radiation.
if you are planning on drawing fresh air through that forty five (sticking out of the ground) won't that defeat the purpose by drawing hot air into the system / why not a closed system that just keeps recirculating the cooled air through the system (loop out/loop in) if all else fails just get a simple swamp cooler, they worked well for me when I lived in Sierra Vista / Fort Huachuca
How come the pipe is such small diameter?
Why not put all 3 pipes in same trench?
I plan to build similar system in near future so just curious.
I’m in northwest Arizona
Great work y’all
Are you reasonably close to Yuma? I can help with back filling the trenches if so. Looking at the mountains in the backdrop, looks more like golden valley.
You guys are doing great. BUT, if you’re going to spend time in a deep trench like that you need to have Jess there with the phone ready.. Arizona dirt changes consistency and when a hole is open it can collapse. Dirt is heavy I’m sure you know.. a collapse on a hole that deep may be as much as 5 wheelbarrow full crushing you. You can rent shoring equipment it’s basically a ram that runs on water and holds the sides apart in your work area.. please be safe. Neither of you can lift that weight in dirt fast enough to live through it..
Good job. You probably over did the pipe fittings. No sense using that much primer and glue for that application. It's not like you are trying to prevent water from leaking.
#OSRL I don't know if I missed it but what are your ground temps at? I believe you're at 6 foot deep and also I imagine the holes are for humidity or etc.. I don't think I've missed a single episode but I don't recall. Thank you.
read what bear has to say!!!!!
Hello, looking at some of the comments, I ended up searching for info on earth tube airconditioning and so funny I ended up coming across one of you old videos on using solar chimneys. ( th-cam.com/video/iGhmOpgTS2A/w-d-xo.html ). Are you planning on adding this to your geothermal cooling? It made me smile to see that you have been at this for a quite a while and you are still consistent with your efforts. I hope all goes well with your projects!
Are the holes on the bottom of the pipeline in order to get rid of any condensation?
I know it was mentioned in a comment but have you imagined what it would be like if the walls of the trench caved in burying you while you are working at the bottom? I was going to work in the bottom of a similar trench when I was about to install pipe for my geothermal heat pump when part of it caved in. My ground was very hard and I did't think it could happen but it did. Needless to say I never went down in that trench again.
Hi guys I've been watching your channel for years now and I just want you to know what an inspiration you are I know that it's hard work I've watched and I'm really impressed by you guys you're uplifting hang in there you're doing an awesome job thanks for sharing Your lives with us. And I also pray that you'll be immensely blessed this year. But regardless I'm sending you love and joy I think you're awesome.
Those tunes need to be at least 10"-12" round diameter....given that distance from the entry.
Excited to see the geothermal cooling come together! Happy anniversary Lluvia🎉
Working in ditch deeper than waist deep without protection is crazy. And won't work anywhere there is any humidity
I imagine you explained what the pipes are meant to do, what reaction did the Excavator have to your plans?
I'm bumfuzzled why you need pipe coming out of the ground on the far end away from the house.
they be no way he do all that by hand....and why the day...why not...early am....and late evening...avoiding the heat...and why dang not the front end loader ? ..... ?????
Can you explain how the system works and the reason why you seal the pipes together when you drill holes in the pipe?
All that Soil you could build a at grade dome at the other end of you home build wouldn't' that be something? lol
What's the second trench for?
Lol, I'm sitting here saying go Jim go, you can do it, as you were assembling the tubes. I'd hate to see you have to backfill all of that by hand.
Just a suggestion to others...
Installing a system is a lot of work ...
For there to be problems later...
IMO
good idea to help prevent potential problem..
Install the pipe sleeve..
Same as they use in leach fields
Or filter fabric
Install Filter fabric between the gravel and soil...
Are you using a laser level for the bottom of the trench.
Just a suggestion... dig the trenches at least 1/4 inch per foot fall.. to a sump pit.. to deal with any water back up
What is the purpose of the holes in the pipe? Won't the soil and bugs get in the pipe...
Happy anniversary to you Lluvia! ❤ I hope you have a great day full of fun and adventure! ❣️ I hope you get a special treat or toy or both! You are such a good girl and you deserve to have your great owners that love and treasure you each and every day! You guys are doing great work on those pipes! I can't wait to see how good they work to cool your house 🏠! Thanks for all the great work on your videos! I love and look forward to them. Rob
I'm happy for Lluvia's anniversary, she seems to be living her best life! I'm not understanding the science behind putting holes in the earth tubes but I know you guys put a lot of research into your projects , so, great job.
I do not get that either....I guess they want dust and water in their pipes...
The cold ground will cool the air in the pipe and pull water out of the air with condensation. Without drain holes that will eventually block the pipe.
@@rainman7992Technically, you put a sock covering over the holes to help alleviate that.
@@juglore Thanks for the explanation!
@juglore Earth tubes are to be installed in an incline from lower(outside) to higher(inside) as it enters the home for condensation concerns. You NEVER EVER drill holes into earth tubes. It weakens the structure, promotes fracturing & it will pull monsoon rain water into those holes atop gravel like that ultimately defeating the purpose. The deepness of those pipes means it's going to contend with a LOT of PSI already that far down
ok-did I miss it? You guys covered the end in screen-right?
