Air level system losing air

The Ultrasonic looks like the only route left we have exhausted the soap route all though the underside of the coach is a lot cleaner now than when we started so not all bad. lol

Sorry for the late reply. Be sure to check the ping tank hoses. Large hose 3/4 from ping tank to top of air bag.Hard to check but i had 2 bad. I have replaced 2 on left side waiting for riht side to go bad.

Great thanks for the tip

Is your coach dropping, or just your guage needles going down over time?

Your air gauge showing air loss over a couple of days may not be a problem at all. Your HWH leveling system is controlled by the two six-pack manifolds. If the O-rings in the six-packs are not leaking, your coach will stay level even as the air is depleted from the tanks and shows "0" on the gauge. There is actually a small auxiliary air compressor that provides air to the leveling system to provide air pressure when the engine is not running. Your leveling system does use air pressure from the engine compressor for initial leveling. However, once leveled, the systems are separated by the seals in the six-packs. I would not get concerned further until you level it and wait to see how long it stays level. If it will not stay level, it is the six-packs leaking regardless of the air pressure in the rest of the air system.
