![Above Ground Pool Fountain [Quick Install]](http://i.ytimg.com/vi/W9WQ2GHzG8w/mqdefault.jpg)
Our in ground pool got pretty warm, but we put up a couple sails and put them above the pool. Made all the difference in temp and also gives a break from the sun while swimming.
I am in Arizona and my inground pool has a sprinkler/aerator built in. When off by end of July the temperature would reach 95 degrees. So I turn it on around Father's Day (mid-June) and turn it off late August.
If you look at a daily temperature chart you'll see the coolest temperatures are from 3 to 6 AM, so that's the best time to run your pump on high speed.
We use a sump pump and a floating fountain in our inground. I run it overnight to keep our pool in the low to mid 80s. On nights that dip into the 60s pool temps can drop into the 70s....feels amazing in the dog days...
Would love to see a video of you varying the amount of time at night it runs and measuring the amount of temperature change. Kind of like the ice maker video where you play around with all kinds of variations to measure the affects.
I'm considering doing that. Day temps really messes with the results.
Humidity (dew point) also has a major effect on the ability to evaporate and cool. The closer the wet bulb temp is to the dry bulb (outdoor air temp), the less evaporative cooling is available. You can google evaporative cooling charts that will give you the most favorable temp/humidity combo's and get an idea of what the temperature drops will be.
The cooling effect is caused by the evaporation of water from the spray. That sucks the heat out of the water droplets. Another trick that helps is, like @donnaskin mentioned below, keep direct sunlight from hitting the pool.
I totally meant to say evaporate cooling could be to blame. Been thinking about that today.
As others said, the evaporative effect makes a huge difference. Here in Phoenix, when it is 115 during the day and 90 over night, our pool gets up to 95 degrees. Your pool is shallow, so it is gonna get hot and stay that way. The aerator makes a 5 degree difference and that is all it takes to make it feel less like a bath tub. For what it's worth, if your chemicals are kept proper, it won't matter if you only run the pump at night... the sun will eat your chlorine regardless, so if electricity is cheaper, run your pump from 10 pm to 6 am and save some dough, all while cooling the pool.
Jacques Cousteau would be proud! (underwater vid) 🙂
We have an in-ground pool (Houston), and I made a sprayer/fountain out of a cheap water feature pump and a 6' piece of PVC. Our pool returns weren't compatible with a standard "attach to an existing pool return" connector. However, this does allow me to run the sprayer all night long when the air temp is the lowest and getting the most water temp drop. I've seen 98-99 degree pool temps drop to about 89-90 by morning. I'm currently experimenting with a more advanced DIY "pool chiller" that basically is a trash can, some layers of grids inside, a pump, and a fan on top to pull air through the unit to be much more efficient at pulling heat out of the water. Essentially a miniature chilling tower like some commercial units.
Interesting approach.
Thinking about buying some pipe, a pump and a few bulkhead fittings? Would be really interesting to put that fountain on it's own separate non filtered system and see how cool the pool would get with it running 24/7.
I'm already playing with some ideas
@@TKCL Floating bilge pump even. Keep costs real cheap and avoid cutting into the pool before knowing if it's worth it.
These fountains work by evaporating the water, which will mean you have to refill your pool with that much more water to maintain the level.
A year later and it's very rare I fill my pool. The occasional rain takes care of that.
I made one of these 15 years ago for an in-ground pool. I just used regular pvc fittings. I drilled holes in the end caps. I drilled holes in the side of the bottom elbows to allow circulation flow. Back in 2010 it cost me $8. I run my pump over night as you get more of a cooling effect as the temp difference between night air and pool water is greater providing a larger driving force for heat exchange.
I admit, your’s is prettier! Great video! I bet in 2024 the pvc fittings I used are probably $30.
And I think I paid $20 or 30 for this. Totally worth it.
Essentially a cooling tower.👍
Evaporative cooling, yes.
Yeah! ... Ice maker! Here in my country at times we can NOT use the COLD water..103 at the tap
What country? That's crazy!
Especially because have an above ground pool, only aerate at night and its cheaper to run your filter at night, anyway. All you need is to turn you water over through the filter so many times a day, you really don't need to run it during the day unless you've got a mess of people in there, sweating,peeing and wearing sun screen or lotion.
I have an in ground here in Phoenix, and my aerator keeps my pool under 90, and its way hotter here. It does help that it's an in ground pool, above ground has more thermal material to absorb the daytime heat of the day.
It's basically given a place for the water to easily evaporate into the air thus taking heat with it.
This is 100% true! We did a video about this with a DIY one and it literally dropped our pool 10° overnight! That one is awesome - love the adjustable aspect.
I was also planning a DIY one. Hard to justify for as cheap as these are.
You have to be losing water to evaporation....how much make up water is added daily with the hose?
Daily? I usually add 1 inch a week with my hose.
Nice fountain. It’s bad that is so hot outside that it makes your pool more like a hot tub😂
Yes it does
Good day all.
Good afternoon
As a person who lives in south west PA we have large heaters running even in the summer to heat the pool making it warmer. I didn't even realize being too hot was a possibility..
It for sure is when you have months of 90-100 degree days with high humidity and a lot of sun.
Evaporative cooling works best with lower humidity. Unfortunately, at least in the south, humidity gets lower during the day and higher at night depending on prevailing winds. So much of the heat transfer occurs due to the lower overnight temperatures. That said, the temperature overnight here (north of Houston) was a chilly 86 degrees F. You really need a conductive heat exchanger with forced air or a protective UV cover in some challenging environments. We like to swim closer to happy hour and the pool just heats back up to 92 degrees without blocking the UV no matter what you do overnight.
Cool little life hack fact to keep your pools from getting warm. Did you know that having your inner pool colour white causes the water to take longer to heat up because white is a great reflector of the sunlight like for example, white or even having lighter colours reflects heat back to space keeping it cooler while darker colours or black absorbs heat making it hotter. Having white or lighter colour inner pools also takes longer for the water to evaporate because of it being less warm due to the suns heat, being reflected so go white inner pools. You can search up white keeps you colder and you will see. 👍
This is perfect!
Thanks for sharing
Glad you like it!
Actually I am interested in the light. I have a in ground pool that some idiot installed with no light. I notice that you have a corded one.
Yes I bought a 20w light from Amazon called a lymle or something like that. Works very well.
New follower. I’ll have to try that. Our pool has been really hot in North Texas
Welcome to the channel! Ours helps the temp tremendously.
Great information!!
Thank you for watching
Future experiment. Geo-thermal. Loop some pipe in the ground on the return side.
We are already thinking the same. I've been hinting around to this. It's on my list of projects.
Would have to do a little diy temperature test to see how deep you'd need to dig in your hot and sandy soil. Generic answer is 6 feet. Two feet would about do it here in washington state. I think we've broke 90 5 days (but we did see 116 2 years ago!). You might be way deep with extended high temperatures. I'd be curious to see some of this experiment if its not silly deep you could totally pull it off on your own for not a huge expense.
It's for sure on my list of to do items.
great tool for above ground.... us in-ground folks usually only have our jets on the sides so there is not enough real estate for the fan to spray :( good video thanks 🤠
My friend with an inground is running one of these as well.
I knew there must be some issue with your pool if you never showed you enjoying it yet. Always all fountain in the background. Evaporative cooling is underrated, it does wonders in so many different ways.
Yes and I totally meant to mention evaporative cooling.
Is there a way to completely shut off the fountain but still have the water circulate?
Not completely, but you can make it where it doesn't spray much at all.
My frist though is why in world would you go with that coor? It cant help that's for sure.
its so dark it makes me laugh thinking about a hot pool
Didnt know people cool down their pools. Mine is 85+ most of the time and I just installed a heat pump
In the south we sure do, it gets miserable here.
Clark & Deborah:
Thanks, Andrew, ordering one now
Let me know how it works for you.
People need to be aware that anything like this makes chlorine usage higher, even water falls.
Like people have said, a sail clothe above, or we have a cage on our Florida pool with UV sun screen installed, make things much better.
Our Arizona pool we have a heat pump (too expensive for some) but, it heats in the winter and cools in the summer.
Might be true, but I'm chemical free so I don't tend to watch that. Our big turn off with the sails is they don't look good and block your view.
Regardless if it does use more chemicals, it's at the point for most people it's so hot you can't use the pool. I'm voting for anything that will cool it off.
Its using evaprative cooling
Why didn't you install a center Drain in the center of the pool, that way all you would need to do is turn on the pool pump. This will bring the thermocline temps that are lower at the bottom of the pool to circulate the cooler water up to swim level?
First pool, not a bad idea.
Question??? I bought one from Amazon, how do you take the jet off what tool did you use???
Every pool is different, I unscrewed the jet from the inside of the pool with pliers.
We have this in our house in the Palm Springs area. It works great. Just as advertised.
Do a bellyflop! 😁
After the deck 😉
For the readers, the reason based on physics is below. you need to run the thing when the air temperature is cooler than the pool temperature. I can say one thing, oxygenizing the air isn't doing a thing regarding the temperature.
It's evaporative cooling, might want to read into it. Plus contact with air causes cooling. Call bull all you want, I could care less as long as my pool is staying cooler.
@@TKCL I did read up on evaporative cooling for pools. you running the sprinkler in temperatures equal to or hotter than your pool will do nothing except increase the heat of the pool. running the sprinkler at night will cause the sprinkler water sourced from the pool to exothermically release the heat from the water into the cooler atmosphere and when it enters the pool the water will be at a cooler state. However I dont recall any of this discussion in your video. In short, the sprinkler takes hot water which cools it as it flies through the air and reenters the pool. Ok this works, but the important thing is to run the sprinkler when the temperature environment is cooler than your water. I will edit my comments above. certainly cheaper than active chlllers.
I absolutely did talk about running at night and cooler temperatures. Also mentioned my timer is set to run a few hours after dark.
I don't understand why you haven't put up a sail to shade at least a part of the pool. Shade will cool it much more.
Because I don't want to ruin our sky view or see the sail right out our main windows of the house. This is cooling the pool well enough to make it comfortable.
88 is perfect. That’s where I heat my pool at
85° is perfect to me.
Make an effort to run the fountain as much as possible at night. The entire cooling cycle takes place while the water is being sprayed into the air. If you can expose that water to cooler night time temperatures, you’ll knock quit a few degrees off of your low temp.
Evaporation is primarily what cools the water not the air temperature.
its called 'hyper-cooling'. waterfalls are natures version of this.
Evaporative cooling
Amazon: Item is currently unavailable, boo,
I put two links. Check both.
Does it evaporate your water more. Than if you didn't have it?
Yes a little more. We are in a month long drought and I've only added water 3 times.
It’s releasing heat into the air. Basic physics. Put up 4 posts and a shade cloth. Keeps it cool and refreshing.
Evaporative cooling
Does anyone live in Texas or Oklahoma
90 degree water is just fine when it’s 118
dude, how come we didnt get a preachers seat at the end of the video. lets go dude!!! quit fuggin around
No no no, Jack knife!
@@TKCL or if you really want to impress...a nestea plunge...do it right...body stiff as a board.
how do you use you pool cleaner with that set up
My pool uses an ionizer.
96 degrees!? Hot tubs are comfortable at 104 degrees😲
My pool isn't meant to be a hot tub.
I have that fountain and it helps but honestly the thing that made a tremendous difference was putting one of those solar shades over the pool. I'm talking about those triangle or rectangular covers that are breathable that they sell on Amazon and I think they do call them solar shades. Since you're building your deck this would be the perfect time to add posts/poles make for one and I promise you it will make a huge difference - five times what the fountain did.
a shade can only reduce the temp to ambient. An evaporative cooler (what this is) can reduce it below ambient.
@@zachansen8293 no the ground is cooler than ambient and shade stops UV heat absorption
Did the same. Live in Orlando and that sun is crazy hot. The shades & fountain helps.
So, in my own personal experience, I have a pool and I live in the DFW metroplex where the summertime temperatures reach, well over, a hundred degrees and my pool reaches up to 95°F and usually hover around 93°F during the day. However, last year my neighbor’s large oak tree would shade most of my pool during the day and it took until almost the middle of June before the pool temps reached the upper 80’s and by the end of August the water temperature would be, roughly, back around 85° to 88°. Over this past winter my neighbor had the tree cut down and now this summer I haven’t had any shade, at all, over my pool, hence the constant 90°F plus degree water temperatures, and so I built a fountain that I hook up to my Polaris pool cleaner hose so that I use the water that’s already in the pool and I am not adding fresh water to the pool. With no shade and my fountain running my pool water temperature drops a good 3°F or so and that makes a very big and noticeable difference. I have two of those triangle solar shades that I am contemplating putting up over my pool, but I haven’t done so, as of, yet. Also, it’s worth noting that my pool is an in ground model and is covered with gunite with a plaster overlay that is an aqua color. It is 3.5’ deep on the shallow end and about 7.5’ in the deep end. With the shade from the tree, in years prior, and the 7.5” depth of the deep end, my pool water temperatures would take a while to creep up high enough that the water didn’t seem a bit chilly upon entering. Now, this summer and with no shade, there is no “chilly” entering and for the last 2.5 months, and still right now, it feels more like a warm bath!!! The sprinkler/fountain is an absolute must if you want somewhat enjoyable pool water for this time of the year.
Fountainshave been used for centuries to cool. When I rode motorcycles out west, I loved going by fields being irrigated. The drop in temp was amazing!
That is because the water is cooling the air, because the water is cooler than the air. Spraying hot water into hotter air doesn't do a whole lot.
Or (and I know a lot of you were thinking it) get 3 or 4 chest freezers, modify them to ice makers, set up chutes to dump that ice into the pool. 🙂
🤣
It would mess with your pool chemistry. Also, if you do the math you would need hundreds of pounds of ice to make any difference in a 20,000 gallon pool.
As a fellow Southerner, SC, thank you so much for your video! My husband and I had a above ground pool installed last September, so this is our 1st Summer with it. We got the fountain after seeing your video. It really does a great job, and we love the look and sound of it also.
Thank you again!
Glad it was helpful. We enjoy the sound as well.
Take one of your ice makers and put a coil (radiator) in it, and run your pool water through the coil. A pool chiller! 🙂
Lol won't put a dent in 16,000 gallons.
You can put a toaster in your bathtub too and turn it into a jacuzzi
@@BRAVITSit'll be so hot, you'll die of excitement 🤣
@@TKCLalternatively you could just buy 3,000 bags of ice every time you want to cool it down. 😂🤣✌️
@@BRAVITSlmmfao!!! I just tried this and I feel weird af 😂
If I could make a suggestion. I have a very similar setup for above ground pool. I would make a shed or an enclosure around your sand filter and pump to help the lifetime of the pvc. I did all new plumping on mine last year and this heat has made them crack and break .
That is on my to do list.
Get a 20' x 20' sun shade and run the fountain.
Hi, Andrew! I wondered about the temperature of the pool water. Does it cool off enough to swim after dark or early in the morning?
It feels a little better after dark.
Good review Andrew, that should come in handy for a lot of people. Your pool and deck are looking fantastic. 👍👍❤️❤️🇨🇦
Thank you for watching
Pretty cool, I helped some customers a while back with something similar but with the prices of pvc now you got the deal 👍
Glad you found the perfect remedy to help cool the pool.
Not perfect, but definitely helps.
It would be interesting to see if you ran the filter return pipe under ground, if that would cool the water. Maybe dig a 20' trench about 3 feet down. just an idea.
Way ahead of you, already have that job planned out for a future video.
Yes, that will work, but 68 degree temp is at 6’ to 8’ deep. Not sure 3’ will get you there.
In Arizona, with less humidity, but 110+ is common. I’ve been doing nearly the exact same thing now for 2 years in our in-ground pool with identical results. I adapted the in-ground aerator with these exact fountains and it works way better than the small aerator typically installed in pools here. The key seems to be launching the water in volume, high enough to cool as it moves through the air.
Yes it was after the eggs
Hello Andrew how are you doing buddy? It's been a while with me MIA. I hope you are doing well buddy & your wife. Man that is Amazing how that 30$ dollars Machine cool down your pool like that so fast man. You have a nice pool man. Man you are right about that heat man. I broke down in my truck 🚛 when i was in FL at the end of July. My Airline crack and loss all my air pressure. I was Fixing it in the heat & Sweat my butt off.

Andrew i hope you are doing well buddy & you take it easy buddy.
Sorry to hear about the breakdown Mack! Good to hear from you, hope you are doing well.
We are from NC. Have an inground pool. Have been using one similar for 4 years now. We run our pump 24/7. Keeps pool temp around 86-88 degrees. As always, love the videos.....
I can't afford 24/7 🤣
I made my own years ago for my inground pool.
I used and old adapter from my old Polaris and piece of 1/2 pvc pipe and an adjustable nozzle sprayer.
It works great.
Yep. I get it with the pool being uncomfortable and hot. We are in burbs from Scottsdale AZ. We have in-ground pool and also run the waterfall and/or aerator to break the surface and cool the pool down. It works. I’ve seen vids where people make their own with PVC etc…
Might need to put up an area for some shade? Like the fountain
Maybe later on. Only partial shade
Also a pool sunshade also helps. 🙂
Yes, but blocks our beautiful view of the night sky
@@TKCL understandable 😆
I had the same problem but thought the fountain would cause to much water loss by evaporation. I chose to go with shade cloth over the pool. PROBLEM SOLVED!!!!
I add 1 inch of water a week, I don't consider that to be much loss. We don't want shade cloth because it ruins your view from the house and pool. We swam after dark last night enjoying looking at the stars.
Latent Heat of Vaporization. The water spraying in the air evaporates a little before it falls back in. The energy to evaporate the water comes in part from the water cooling the water.
Exactly, evaporative cooling.
Great video by a really believable guy.
Evaporation is the word you're looking for. 3:00 to 7:00 might just be more amazing. I'm curious how much water you're adding each day?
Really wanted to know how it worked. Amazing, it does so well. Game changer for folks in the south! Thanks!
For the $30 I paid, I'm impressed.
@@TKCL I would agree! As you know, that's the cheapest part of the pool! Lol! Take care down there!
I have always wondered about setting up pex pipe under ground for “ radiant cooling” for cooling a pool. Also very interested in aquaculture and wondering about the same thing for maintaining stable water temps.
You and I are thinking the same, that's on my to try list.
Yes, that would work very well. With enough pipe deep enough in ground. It's called geothermal and is used to heat and cool houses. The ground stays a constant 67 degrees six feet below the surface. Had it in my home in Michigan, extremely effective way to heat and cool!
That's my plan
I wonder what size pipe it would take and how many feet to drop the temp? I have a water holding tank/water softener system 100 ft from my house. The supply line is 1” pex buried 5 feet deep. In the summer you get hot water out of the cold water side of the shower 😂
Hard to say because you'll be pushing thousands of gallons through it.
Shield filter and adjacent lines from the sun helps
So we ran a pipe underground around the pool. I put a shut off valve on it so it can be adjusted and turned on or off when needed. This is connected to the return from the pump and the pool cools down quickly.
That's been one of my big planned projects I've hinted around to, geo thermal.
@@TKCL it works 👍
i would love to see you do a belly flop!🎉🎉🎉🎉🎉🎉
After the deck
@@TKCL sounds good lol!
More evaporation too right?
Correct, but I rarely have to add water. A few rains keeps my pool topped off.
First
aaa second maybe???
@@shanefairfield938 nope
Yep!
@@TKCL I'm confused 🤔
Shane's correct Cash! Nothing to be confused about
25 years ago when the kids were little, I collected several return nozzles for our above ground pool...
One in particular was something similar to *CMP 23315-030-000 1.5 in. MPT Gunite Spa Jet44; Pulsator44; White*
It is a spinning nozzle and I was able to fasten it to the return line out, on a 90 degree elbow with threads that worked with the return line. Replacing the eyeball return nozzle.
Using a 90 degree elbow works great, as it circulates the pool, and any debris needing vacuumed was concentrated in the center of the pool.
Thats cool!
That sprinkler will really help keep your pool cold for you guys. 🤠 thanks for sharing.
Yes it will
Keep in mind that aeration like that removes all the chlorine in the water being sprayed. So dont have any chlorine feed through that fountain.
Very true, but our pool is chemical free.
@TKCL How are you sanitizing the water? Without a sanitizer, recreational water illnesses can quickly spread, with symptoms such as rashes, skin infections, diarrhea and swimmers' ear. Use of a sanitizer such as chlorine will help kill bacteria and various pathogens that can make you extremely sick. It also oxidizes organic materials. While on-topic, I should mention that many people believe that burning, itchy red eyes from swimming is caused by excess chlorine, but rather, it is in fact typically a pH problem. Get that pH right and the eyes will never burn or itch or get red from swimming. Having the pH in range will also help keep algae from forming. 30-year pool owner here. Happy swimming! Great fountain!
I just got mine in and installed it today. I have an in ground pool. I realized before the product got here that it wasn't going to work. The reason is I have a variable speed pump and I run it at a lower rpm throughout the day for energy costs reasons. Well I threw the unit on a return and got exactly what I thought. A very small fountain lol. So I decided to crank up my rpms on the pump just to see. Didn't really make a difference and didn't want to max the pump out as it would defeat the purpose of a low cost chiller unit for a pool. I am running the pool all night tonight to see if the little fountain I do make will adjust the temp enough to make a difference. I still believe the product works but just for above ground pools with one return as shown in this video.
First ?
Not today sir 🤔🤔🤔

My in-ground pool came stock with one of those they're called aerators.
That's great
I imagine one downside is keeping your pH in check. Worth the trade off though
I've not had to do anything after a year, but yes it's worth monitoring.
We have the exact opposite problem up here in Canada. During the summer when we have pools we need pool heaters or the water stays too cold to swim in.
I like your idea for cooling when the pool heats up to 96F. I created a floating fountain using a Rule 1100GPH bilge pump connected to a 50-watt 12-volt solar panel. Now I am thinking of adding a trickle charger and battery to run at night. I like the sound and the aeration it adds.
We love the sound as well
Good video. Yeah, it has been super hot. It's good to know about the foundation for the pool.
A sprinkler spraying over the pool. Did that in 1970's dude.
Can put some shade over 1/4 the pool and it would make a large difference as well.
I'm here
👀
Nothing new. It's called an Aerator. Master Pools installed them as standard equipment back in the 60s in Arizona.
Didn't say it was new, but judging by the views and comments not many are away of them.
@@TKCL After reviewing the comments I'm surprised. I guess pool companies no longer install them as standard equipment in hot climate states. They do work well as you noted. Take care.
Increase water evaporation
Some yes, it's a worthwhile trade off to not have a blazing hot pool.
You are cooling by evaporation which when humid limits how much temperature drop you can get. Out west where it is drier your temperature drop increases due to the ability of the surrounding air to absorb water. The best you can typically achieve in very low humidity is about a 20 degree fahrenheit drop. That is why you see evaporative coolers out west and not so much in the east. The two things that also occur with evaporating water with outside air to cool is an slight increase in carbon dioxide from aeration and the minerals that are in water drop out increasing hardness, mineral deposits around the water edge and an increase in total dissolved solids.
Suggest you research a ground loop thermal system utilizing a DC pump with solar panels to get water circulation in the pool.
I do have plans to do a geothermal ground system.
I worked in industrial water treatment for over 35 years, always interested in alternate ways that are verifiable. I worked on 1 remodel of low income brick apartments, single story and they used a ground loop thermal cooling system and packed cellulose material. One ground system that was installed at a county building put the lines a couple feet down under a grass field that was watered. Sounded great and worked most of time but it worked so so when it got above 100f. When the drought hit hard and watering the grass became taboo, the whole system went to crap. The other problem was when it got overheated being low the lines would expand and then pull apart at threaded coupling location and if not glued well enough they failed as well. Going down is better unless you are deep enough horizontally. My work was with cooling towers out west, steam boilers, hydronic chill and hot lines domestic water sterilization. Each area is different, type of soil, type of wet or dry seasons. Most diy type ground loop systems tend to be in mountainous areas.
this is funny because we can never get our pool warm enough lol
