Relative Newbie here (1 year), looking for advice!
When I bought my coach last year, it had a blown air bag, but it came with all required repair parts and the "threaded rod" in place for transport. I installed the new bag and valve, The system pumped up, and not knowing how long to leave it on or how high it would go, I left it on until the red hose coming out of the second stage of the compressor blew open (I assumed from compressor heat). Fortunately, the check valves kept the system pumped up, and I replaced it (with 160 psi rated ice maker hose and brass compression fittings). Now, whenever I'm warming it up and running the compressor, and I get sidetracked for a bit, it blows that hose (after about 5 minutes or so). I've blown and replaced it about 4 times now.
Now, I figure I've got a stuck pressure relief valve somewhere, since it doesn't seem like GMC would build it without a fail-safe. I've considered replacing it with a run of copper, or a 3000 psi flared hose I have left over frome some equipment I used to work on, but I figure it will just blow at the next weakest point. Can anyone shed any light on this dilemna?
It always blows close to the pump head where it is hottest. I've also considered the possibility that the first hose was 33 years old and the ice machine hose, though 160 psi rated, loses integrity when hot.
Thanks in advance,
