Unusual propane plumbing???

[TenOC]

We have a 2014 3100RL Montana we bought it used on the non-door side the propane tanks are connected to the automatic crossover and what I will call a standard way, no problems.

However, on the door side connected to the propane tank is an in-line pressure gauge (no problem) then the flexible propane line is connected to a single pressure regulator (much like this one in the photo below) before connecting to the iron pipe which crosses over to the other side. I do not know why there is a pressure regulator on the door side. Your thoughts are welcome.

A problem that may or may not be related to this configuration. There appears to be a propane leak that we cannot find. When we open the propane valve on the tank on the door side as expected the pressure gauge shows full pressure. Then if we turn off the valve on this tank very slowly the gauge pressure drops to zero. We have use soapy water to check for leaks and cannot find any leaks. I do not smell any propane other than the normal smell that is usually associated around the tank after one fills the tank

"High-pressure regulator is designed for high-demand propane equipment, primarily used for dual-bottle psig setups with distant separation applications. Regulates 500,000 Btu/hr or 30 psig based on 100 psig inlet."

The red regulator reduces the pressure from tank pressure (100 psi) to 30 psi before sending it across your rv to the auto-switchover regulator which reduces the pressure further. It's for safety.

yup. every 5th wheel I've seen has this arrangement. Unlike a TT with the propane bottles external and very close together a 5th wheel has propane tanks seperated by a reasonable distance AND inside the trailer. So the high pressure regulator is a safety precaution.

Both of our fifth wheels have been set up that way. Why do you call it "non-standard?"

See my answer on the MOC forum.

All OK. When the propane is shut off the regulator vents the propane for safety.
