Который раз убеждаюсь, что идиотизм - дело международное. Когда за дело берутся люди, которые не понимают что делают, получается такая история. Хорошая работа JMT.
Should have added ball valves to isolate the pumps in case of repair or taking in consideration of GPMs to the chiller
The amount of knowledge you have is inspiring
Thank you Melo! I appreciate that & I'm glad I can inspire you. Stay tuned for new videos every week🔧⚡️
Holy moly that’s a tough spot to be in. Good job with what you were able to accomplish
Great work for what you were given. I love how you said “like a normal person”. Lol great video look forward to your next one JMT!!!!
hell yea, yall didn't get overwhelmed you just figured out what to do, got the job done and handled it like a boss
I'm willing to bet this was work of an employee from from the building.
😂😂😂 Thanks for watching & Stay tuned for new videos every week🔧⚡️
Great video. Definitely inspires me to continue to learn as much as I can
Looks like they called the right guy to clean up that piping mess Jumper man tech!
I think I'd go to the original customer, show them the issues and ask them if they want it done right or done by a hack
Great video, most people think is HVAC techs make 45k a year, you’re proving why we justify 150k a year, if not more✌🏻🤛💪
Another great video. Thanks for sharing your experience w us. Definitely helpful and interesting vid
wow🫠 what a mess but you cleaned it up 👌🏼👌🏼👌🏼 amazing work JMT💫👏🏼
Nice video , first time watcher ! Loved the outro as well

Great job
Thank you!! 🙏🔧⚡️
As soon as you pointed out the water supply/return lines, i was like "oh man, someone effed up" lol.
One big thing i learned from my time as a tech. If a senior tech pulls you to the side and just starts talking to you about BASIC, BASIC stuff. Lol guess what they are tryna make you aware of what you did wrong on that job lol. Great video, good information. JMT the man. This dude is the New Jack of HVAC/R technicians.
Why not just clear all that out instead of hacking in more goofy fixes? Was this a fixed price job?
Great work that tower most definitely has legionella though
Great video
Thank you! Stay tuned for new videos every week🔧⚡️
question, is there a reason for making the output on T from the pump outlets vertical and not horizontal? I'm not the most knowledgeable person but seems that can cause air entrapment in that output "hump" as well as adding an extra elbow or two into the system. I don't want this to come across as snark but a legitimate question from somebody who is very limited in such applications/tasks.
good work man, I was expecting to see you upsize the supplies of the pumps though.
Thank you Andrew! If it was really up to me, I'd get rid of everything there and redo the entire setup properly💯 Stay tuned for new videos every week🔧⚡️
@@JumpermanTech one thing that technicians (but also customers) need to be aware of, is that they get what they pay for. Ive been in similar situations where i know the right solution, i call in to my service manager and blare it out but then you get that "hey, we only got approval to do x, y and z". Ive straight up had property managers to my face go "i understand you are making great recommendations. I feel comfortable with your companies service and i trust you are doing better than the last guy, but still, we only have approval for. ..".
YES! This video HAS confirmed that we are ALL in the Turd Polishing Business! Great job JMT! The first few seconds of the clip I was like Whoa!!!! WTF is this!!!? If that was me I would have cut everything out, and start again!!! Just wondering why did you leave that smaller pipe section on the discharge of that blue pump? Why not replace it so to avoid excessive pressure loss?
It looks like the dingle that installed that rats nest sourced a smaller diameter pump, if you look at the piping, it doesn't look like there are any reducers on the pump itself. Smh.
Hack job on retro pump , looks like amateur hour no spec's on added pump to meet peak demands , with VFD speed controls layout plan of piping backwards , to minimize pressure loss with less fittings using 45 ° in place of 90 ° unless back pressure is needed on run to cooling tower ✅☝️👍✌️🤔
Good eyes. I do chemistry and have seen some wild configurations....
Thank you Michael! This one was ridiculous. Lol. Stay tuned for new videos every week🔧⚡️
Why brazing? I would think that soldering would work a lot better unless there is something i am unaware of with commercial stuff.
Fridgies can't solder.....but we can braze though.
Ripped all the piping use press fittings it not look of piping if you cut out pieces .
That was what I was going to ask. Either way, good job.
Wonder if you can run 2 45° instead of 2 90° ells on offsets lose a 90 ell and 40 to 50 feet of run nice damage control of hack retro work... 👍✌️💪🙏🤔 ...
Braze is stronger and faster to get done less prep work ... ie no flux just sand. But don’t braze water lines that feed houses or buildings the braze rods contain lead so soft solder is usually the go to for potable water lines.
Common sense. He looked at the system. Looked at the pumps and looked at the suction and discharge side of each pump.
You can see the discharge check valves and the suction screens.
He used what he has to fix the system that was not installed correctly.
Brazing is what he uses. Others have other equipment to work with.
Cheers to your work.
Did power to the heat pumps got turned off?
Should have added some unions and isolations valves off those pumps incase they fail you can read pace it and allow the system to keep running
First look my thougth was to just cut out everything lol
fine
Thank you! Stay tuned for new videos every week🔧⚡️
Great job but this job cost waY more than it needed to usually we are all Vitalic when we bo this little to no soldiering never braze only refer lines cost to much. Hope they test for legionairs
I would have the cooling tower drain into a return tank pump from there to equipment than back to top of cooling tower. Too many turns and pumps have to pull water from cooling tower catch tray. There should only be one pump with proper head pressure. No check valves?
Will to many 90's be a problem in that application?
He is not at a lost to have you in you the best for the job professional at the right price
Haha thank you Neilvester I appreciate that! 🙏 I tried my best! Stay tuned for new videos every week🔧⚡️
I would cut all that crap out an start over. Way too many 90’s.
unbelievable
I agree. It was insane to find that issue. Thanks for watching! Stay tuned for new videos every week🔧⚡️
Forgive my ignorance but it appears that that is all low to moderate pressure water, so why braze when solder can take those pressures with ease?
I have the same question.
WOW !😮
I am a bit lost guys can somebody explain better am really enjoying your videos
Pumps are really good at PUSHING water. They're okay at pulling, but pushing is what they're designed to do, and not having the right amount (head pressure) being pushed when the pump is expecting a certain amount can actually lead to catastrophic damage.
The design of the cooling tower is: hot water comes back from the building, trickles down over the cooling media (for example, cardboard mesh) where a fan blows outdoor air through it to cool it down, and the cooled water goes back to the building in a cycle.
You want the pumps to push the water. In almost every case, you want to pump the water into the building, where the other end of the pipes is up on top of the cooling tower. The water trickles down and collects in the basin at the bottom, where the pumps can pull water from and push it back into the building.
The way it was set up at the beginning of the video is the water was being pulled from the building, pushed from the pumps just a few feet to the top of the cooling tower, and the collection basin fed back into the building. Through gravity and pump suction I guess.
With the price of copper, just the bit of copper pipe used made it real real expensive.
Why braze vs solder here?
I know it cost. Do it right when we have problems. No do ones or return backs.
No insulation???
Do you run your own company?
Holy wire nuts batman.
Haha yeah this one was insane 😅 Stay tuned for new videos every week🔧⚡️
I have too many other clients to get involved with polishing a turd like that. Good for you for being willing to take it on, but I will say no thanks every single time.
Also which style of Dickies work pants are those?!
Is this water tower working with a Chiller?
No its just flowing "condenser water" at a 8° dt back to some random air handlers....Jesus 🤦🏾♂️
Dont let a meth head get near all that copper!
Haha agreed! 😂😂😂
Yeah, went to comments first to confirm but I would of shit canned that old pump and just used the new one.
That pipe cutter is huge like a gas pipe cutter
Definitely a large pipe cutter. That was 2" copper we were working with. Thanks for watching & stay tuned for new videos every week🔧⚡️
👍
🙏🙏👍👍⚡️⚡️🔧🔧!!
Someone should put proper screens on those louvers! Not chicken wire...
Side job Sunday vibes 🤣 Thanks for watching! Stay tuned for new videos every week🔧⚡️
The guy before you had got confused as hell didn't he maybe he didn't cause any pump damage
You take pride in your piping, but that "cabling" looks fine to you? O_o
🤙🏼💪🏼
Thank you Mario!! 🙏🔧⚡️🤙
That's not right either! With no check valve if or rather when one pump fails or potentially just get weak the system will backfeed. There is way less resistance in that direction. An alternative would be to plumb in series. Either way this will fail at some point as it is.
Series? Eh for something this tiny?? Nah man. Parallel is fine. You only need like 10-15 psi. Even in industrial we run like 10-15
@@Username-ng8jy the amount of pressure needed is completely irrelevant. The flow will take the path of least resistance. The system only needs one pump. But with two in parallel without a check valve , if the older pump fails the flow will absolutely not go the way it's desired. It either needs a check valve, reduced to 1 pump, or plumbed in series. As is in the video it's just plain wrong.
@@ceazar75 series is definitely not the way to go. Parallel in this small set up is harmless. Yes least resistance. The flow will go fine especially with a dead impeller. The impeller in the dead pump will create the resistance. It’s just gonna go the way it’s intended. Literally I’ve seen small systems similar as this go for years without any issues in parallel. I think your confusing something with something else man. This set up is very simple.
I see two check valves in series, one for each pump. Am I missing something?
They piped over a junction box cover
should've told the customer that you could've used way less fittings if it was done right the first. I hope the guy who did that was having a really bad day.....
Jesus what a mess. Do you ever offer to clean cooling towers or are you busy enough where you don’t have to? A lakos filter would clean that water up nicely.
from this video it is completely unclear what subcooling and superheat should be.
lol you're joking right?
It's a big swamp cooler
All the tech in the world won’t fix bad Maint
No pipes labelled and you say you are professional.
👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍
🙏👍🔧⚡️👍👍👍
why do people take on jobs that they arent capable of doing? if you dont have the knowledge, dont do it. your pride will hurt worse when you do the job incorrectly and get called on it.
Building owners going thrifty as usual...
Hack
Damn dude. How did the original installer not figure that out?? Lol holy crap. Cooling towers aren’t that complicated. Nothing much to them.
This job got butchered twice
Why did he braze instead of solder? It’s just hydronic piping. You did the best you can do with big pile of turd.
Because it’s brazed already. That would create two different melting points on joints. I find it easier to braze on larger pipe.
@@Lovin2LiveLife I meant the original tech.
@@kennyw7453 braze joints hold up to higher pressures and more vibration than sweat. And HVACR guys are used to brazing stuff more than sweating stuff. I learned to sweat pipe first and for smaller water and drain lines it's honestly faster than brazing but give soft solder to most HVAC techs and you'll get some shit joints. Sweating requires flux, and when your used to brazing your used to heating the pipe to a higher temp, a temp hot enough to burn the flux and ruin the joint. Then the guy sticks soft solder on it and it instantly melts beads up and falls off unlike brazing rods and the guy says this stuff is bullshit imma just braze it. (definitely wasn't me at one point)
@@jetthardin4927 Haha.
Grate job!! Ya hiring ?? 😅 .... asking for a friend 🥲 lol
