I am loosing air over night on the front air bags. New bags can find now noticeable leaks,spray with soap etc. checking Schrader bellows selinoid on HWH system. Any ideas where I should look?

There is a air control valve behind the drivers side front tire. Its a block about 4”x10” with a bunch of air lines larger and smaller one going to it. Thats where mine was leaking.

Moisture ejectors are a common place that leak. They are mounted to the air tanks in the front, between the frame rails between front wheels


Ride height valves are another common leaking point - located around the top of the front shocks. The first pic was the brand I had on my coach. The 2nd pic is of the brand Spartan sent me. I installed what they sent me.
