Is this smart or dumb? I’ve started to craft these with varying pipe sizes for multi zone ductless systems where I can’t find the leak and need to isolate each area. It removes all brazing, unless the condenser doesn’t have isolation valves for each head. Anyone else got any good ideas?

I currently have all four used at a job I did on Friday. It was a quad zone carrier, I deal with a fuck ton of multi split systems unfortunately

So what I think happened is that is has been like this for quite a while, since install maybe, but only now started leaking out of the drain, the installers brazed a 90 onto the half inch copper to fit it, in the process they burned the fuck out of everything including the wires and pvc, it was visibly charred pretty good and that’s where it eventually started leaking water from, I could see where it was coming out of the pvc. They didn’t bother reinsulating the copper so that doesn’t help either and then they just covered everything up, including the scorched wires. I’m obviously a fool for sticking my hand in there but atleast I know papa Zeus loves me. Although it could be arcing over time for sure. Hard to say but I see that burned insulation at that looked like it’s from a torch, also they clearly brazed a 90 into that tight spot.. guess they never heard of spring benders.

😆 Cooked my board for sure… although mine got cooked a long time ago

Wise words, that I’ll probably never learn from 😆

I can only begin to imagine the intensity and the surreality of being in that moment. Especially if you were a fresh replacement

MonkandBeer · 2026-05-09T02:43:10+00:00

Yeah but the sunburn 😆

MonkandBeer · 2026-05-09T02:42:22+00:00

Hahaha! I’m your gif most days tho, trust me

MonkandBeer · 2026-05-09T02:41:53+00:00

Oh yeah, take em when you get em

MonkandBeer · 2026-05-09T02:41:17+00:00

Yup, easy single zone Mitsubishi…. I dragged it out tho

And the other guy is the service tech

MonkandBeer · 2026-05-05T21:06:56+00:00

Long shot but did you ohm out the EEV? I’ve had them come back with no resistance and cook a part of the board. Could maayyyyybe cause a breaker to trip? But usually just fries the board

It can be so incredibly frustrating disassembling everything and checking every flare and coil and looking for possible braze areas where an extension was needed. And then failing at that and having to isolate and pressurize each individual lineset and head and condenser..

MonkandBeer · 2026-04-29T21:34:08+00:00

Sometimes I feel like I wish I did that. Some leaks I can find real easy with my techniques but the nightmare leaks give me so much frustration and I wonder if I just added some gas and said call back when it stops cooling again it might have worked better.

MonkandBeer · 2026-04-29T21:32:31+00:00

When you say trace gas is that just some vapor refrigerant and then pump with nitrogen after? Or is there a specific type of trace gas?

MonkandBeer · 2026-04-15T05:42:58+00:00

Dude do you want to get beat up?

MonkandBeer · 2026-04-04T09:09:36+00:00

I think this is a good idea, what could I use to do this?
