Luxury Coach Lifestyles - View Single Post - How to find air leaks in the supply system

Richard,
I need to make a correction. The check valve that I referred to in my last post may not be a check valve at all, but some type of solenoid. A hose from the 110V air compressor goes to an air dryer before going to the air tank--at the bottom of the air dryer is a solenoid that drains out the bottom of coach. The solenoid has 2 wires.

The check valve that keeps air from going back into the air compressor is on top & part of my Juno 110V air compressor. It too has a hose coming off of it. I could blow air out, but could not suck air in, so I presume it is working. I have never detected air leaking at this check valve.

As a side note: It used to be that the air gauge in the rear engine compartment would go to zero over night. Today it went to 40psi over an 18 hour period. It appears to me that my leak decreases as the pressure decreases.
