Hot water coil

Machine Repairs
1

Getting ready for this years season. Started to check out all my equipment after winterizing and found out Rv antifreeze failed, must of had a bad batch or very old. Long story short, my hot water coil on my Mitm split. Other than buying a new one from them where else can I get a coil. It is a HDS 3506
Thanks in Advance

Been saying it for years, 50/50 mix with a good 100% antifreeze. Farley makes a great coil ! Get your wallet out. Probably close to 1k. Sorry about your machine sir.

Add another $500 which is exactly why I don’t even trust antifreeze and I blow everything out once I’ve already run antifreeze through. Can’t forget to cycle your unloader too

That is very interesting. I actually blow everything out, then do the antifreeze, and make sure it cycles (have a 5 gallon bucket I use on a loop). Thanks, never thought about it this way.

I’ll PM you the winterizing steps I had to go through. It was horrible lol

Thanks for all the reply’s. I reached out to Farley , good price compared to oem. I will pull the coil this weekend, I have a hard time believing sch 80 pipe split, I hope it is the sch 40 nipples attached to the coil. Got my fingers crossed. I tried blowing out everything from the pump back but air will not move past the pump back to my buffer tank. Should I be blowing it out from the buffer to the pump. No check valves in the system

I used to suck in green antifreeze and watch it come out the end of my hp hose and turn it off. Then put it back into its container afterwards for re use. And tested it after 3,4 cycles, never had a problem down to zero Fahrenheit or a little lower.
