At this point they gotta replace the whole building, everything failing lmao😂
The boiler room gift that keeps on giving. This must be the 10th time you're out here :)
i think of you as a palliative care specialist for that building, just keeping it comfortable and free from pain in its last days of life
Looks like a nice looking rebuild job, they must like you work they got you coming back every couple weeks
Thank you! I'm there every week from HVAC to their refrigeration equipment. Thanks for watching🙏 We operate 24/7 & always get the job done. 100% track record👍
Ya, take a vacation, I just came back from cancun mexico. It was 85 sunny.
Great video,
Thats awesome! Hope you had a great time. I am now currently in Florida enjoying a mini vacation. About to hit the beach! Enjoy your weekend 🔧⚡️
That is weird, that y-strainer is indeed normally mounted in the suction line. If the strainer is mounted in the discharge line the filter is also mounted wrong it must be flipped 180 degrees.
Bro, I enjoy how you work pure detail. My hat off to you keep up the good work!!!!
JMT. I was almost a tech (County Maintenance 10yrs.) Your like the guy i always wanted.. to be! but lord thru me some other curveballs. I wish had talent & knowledge as much as u!
Your Vid’s. at least make me smile, with the humor, etc. I just turned 60 in March. My life's experience of World, would not surprise me in the least.. if all in some of them buildings.. Everything (Is Ass Backwards)!!! Ugh.
I Praise u in your hard work & challenges, etc.
Bless, stay safe & i love trying to pick-up any tech information u always throw out there.
P.S. Let’s not forget Kris, either! He’s been & has been a big part of your help, humor & story, also. Dean, West Central Wis.
Nice job JMT & Chris ... Those words of wisdom written on the air duct was ''A Beautiful Thing'' ...Thx
good eye for seeing the flow directions ....
Looks like small pumps are a heaater for the idle boilers through the exchanger. Plus those strainers need pulled and cleaned. Get some 1/8 and 1/16 graphite gasket sheet and a gasket cutter . Make your own gaskets on site for the strainers and pump flanges.
Yeah Bro I feel for you on this joint!! It’s a pump nightmare!
That loop water must be Trash to keep losing soo many pump seals!! I mean damn it’s not like they’re out of alignment. Since there’s no shaft couplings. Yeah that’s garbage loop water.
I’ve always hated Close coupled Vertical pumps!! They’re always a SOB to work on and remove them. They’re always stuck somewhere with no room and up high on some BS all thread and senior strut!
Sucks that your local pump shop screwed you on that pump. I mean damn the Wrong damn flanges. And to get that beast all the way in that room and it be wrong. Sucks!!
But as Usual Bro you conquered that mess!
Great job. I’ll see you on the next one. I watch all of these videos you’ve done. I’m 35 yrs in this trade and the Service Mgr of a 51 yr old HVAC company. And you sir are doing the Trade a Great Service!
Could you ask the property if there are any mechanical drawings? I would think that's system was designed by an engineer. And there should be some drawings..
I asked the engineer & there are no drawings. Honestly wish I had drawings. Something is definitely off here. After 19 years and so many techs, who knows what happened. Thanks for watching! 🔧⚡️
Job well done JMT 👏
Thank you brother! 🙏🔧⚡️
Jesus bro, you're helping me so much with these videos. You're a legit pro, i cant even imagine the money lol. I'm in the plumbing and hvac field as well and hope you all the best bro
Great Video. Thank you for sharing. Have a nice weekend
They have the Pipe the wrong way round, Return should connect Pipe incoming into PHX and Flow Should connect with pipe coming out of the PHX.
Love your work ethic bro,thanks for the educational videos
New mechanical seals will always leak a little at first until they wear into each other. Had that happen on a circulator that I replaced the motor on and B&G did not have an old motor on shelf. Ended up getting a similar motor and having a machinist make a shaft for the impeller attach to and use a standard off the shelf motor with a shaft coupling.
Hard working team
💯 Thanks for watching! 👍🔧⚡️
P.S. Additional Comment: Also, Probably is reason why curtain pumps keep going out, seeing gaskets leaking, Strainer & seeing crust leakage in different piping gaskets, pump areas, etc. Everything seems could be getting back/reverse, simultaneous, pressures or something weird.
It may all be, Ass Backwards! Just Sayin’. Damn Good Observant, JMT!
Nice work as always Jumper man.
Thank you Steven! 🙏🔧⚡️🤙
i'm glad you had the last pump rebuilt having a back up to change the next leaking one
Does a small boiler loop like that even need multiple pumps on it?
well done JMT⭐️⭐️⭐️
Thank you!! 🙏🔧⚡️
Have you still got the pressure regulator bypassed ? You could be over pressurising the whole system, and blowing the seals out !
It’s hard to tell from the video but it looks like primary/secondary piping. The small pump on each boiler are the dedicated primary pumps that circulate water through the boiler when it is operating and the larger pumps are the secondary or system pumps going to the risers and loads.
The boiler had a primary pump in the back of them. That little taco is like a mini booster pump on the same line as the primary. The large red pump I changed is used on a seperate water line for heat exchange off the boiler water going up the risers. Something is strange with these directions. It's tricky but I Will do the research and figure it out. Thanks for watching!
@@JumpermanTech it's weird. i assume the plate heat exchangers were a later addition installed when the fancoils went in, so the shitty water from the boilers doesn't clog up the smaller channels in the coils. i can't see a reason for the 'wrong direction' pumps being there, unless it's an attempt to control the boiler temperatures to avoid condensation. i'd be interested to see what would happen if you took that pump out and replaced it with a straight bit of pipe instead.
Another day, another leak in this building
Poetry in motion 👍💯💯💯
Suction always goes in to the rotational center of a centrigul pump.
Check the expansion tank, relief valve and pressure regulator. Pump seals are a weak spot in hydronic systems
I have nothing to do with your profession, but I'm always very impressed by your work. Thank you for your great videos.
In my very limited experience looking at large-scale plumbing in hospitals, clinics, and supermarkets (service areas and public areas) they are always adorned with colour-coded arrows along the length of the pipes, with labels printed on the insulation.
This may be unique to the Borough I worked in though (I also live in a country within Europe).
Would this area you are working in have been equally well-labeled when built?
Need some serious water treatment
Back to the drawing board Jumper
If you put headphones on when listening to this video you can tell that bearings are going bad on multiple motors you can hear metal grinding on metal. That building seems like the definition of until completely falls apart we're not paying to get it fixed.
Its pretty typical pump room noise, mechanical pumps and hi freq from the electric motors.
# 4 need to replaced soon very soon like today
Flip the body of the pump around, they put it on the wrong way when they rebuilt it.. you're welcome!
I mention that in his other video too.
Thank you! It only makes sense that the strainer gets connected to the suction side of the pumps. What's your opinion about the direction on the other side of the hear exchanger? It seems the outlet of the boiler is flowing against the little taco booster pump. The boiler itself has a primary pump built into the boiler itself. Thank you!
@oldblueaccord2629 I was wondering what was going on but I see that now. Thing is, this pump was in the orientation of the other 2 I installed. Just curious about your opinion on the direction of flow from the boiler and into the heat exchanger. It seems the booster pump is going against the flow from the boiler. Thank you for your input & thanks for watching! 🔧⚡️
@@JumpermanTech the strainer is more likely for protecting the smaller passages of the heat exchanger(strainer is still installed backwards to flow though),
The boiler loop, follow the boiler outlet as you did, the extra booster circ is backwards,
Lots going on there, job security
@@JumpermanTech I watched your video explanation. Sorry im not a boiler guy Im like you just fix stuff. Im curious if there using a low and high boiler set up the way there tied together. Just my thoughts, I think you did right just to put it together like it was. Its been working all those years. Get with that Laars company and see if they can give you basic layout drawings. Maybe pull the permit from 20 years ago and see who set that mess up. My bet those little pusher pumps are not working.
from Bangladesh
Greetings to Bangladesh from USA🔧⚡️ Thank you for watching!
What a big headache 😊😊😊 With the water direction 😢
Nice job
Those two parts you cut would be good for under that base instead of the rotten wood
Haha facts. That wood was a bad idea in that environment. The other pumps are all supposed by wood if you can see in the video. Bad design. Thanks for watching my friend! 🙏🔧⚡️
😻💚💜💚
💜🔧⚡️
Seals going because the pumps are fighting each other?
hey a good trick to collect the water that comes out drill a hole at the bottom of that garbage can and put a spigot and run a water hose to the drain. its a good temporary fix till you can get a new pump.
That might be why your pumps keep leaking.
why are the gauges on the last one you changed pinned all the way to the max
I think there only 100 psi gauges.
You really gotta watch those little wires the fly off and go right in your eye on your wire wheel
You just did what I was commenting on. Lol😂 cutting that c channel
On to this one jmt money pit
Haha facts. The years of neglect bring me a lot of work. Thanks for watching & enjoy your weekend! 🔧⚡️
Time to sell them some spiral magnet filters and make the janitorial staff clean them once a week.
You probably could replace those pumps with some euro style grunfos magna pumps. They are pretty tough and will save a ton of power if those pumps run 24/7.
no way are magnas lasting more than 5 minutes in water like that. the flow sensors would get clogged straight away.
No pm!!!!!
💯💯💯
God Almighty that place is in constant need of repair(s).
I believe it is due to lack of preventive maintenance.
seals are not very hard to do, do it yourself and save the customer.
I did this kind of work for years all I can say if you want to be a professional get the right tools a hammer some have wrenchs and a cordless impact. Those things save time make you more money right tool for the jobs. It drives me crazy to see things done half assed. If buying a tool makes your job easier then it's a no brainer.
Need a big hammer 😮
My money’s on the pump bring reversed. Probably more than once.
More problems wrong directions and labeling
💯💯💯🤯🤯🤯
Poor water quality.
