Dan, this Spartan MM compressed air system drawing shows some check valves.

There are many different air systems, so without actually seeing what you have, I couldn't say if your system relies on simply the check valve in the drier, or there's one at the intake on your wet tank.

Follow the large discharge line FROM the drier TO the wet tank. If there's a check valve on the tank, you will be able to see it.

I know we used to bypass air driers to get trucks back to work, and those always had a check valve at the tank.

I will pull the dryer and rebuild it. I hope the check valve parts are included in a rebuild kit.

Because the primary service tank also leaks down I am concerned the check valve between the wet thank and the primary service tank is also leaking.

Thank you for pointing me to the dryer.

Did you fix your problem with a new air dryer? Also, wondered how your rear airbags looked like? I have the same motorhome as you. Looking to replace airbags.

Thanks for following up.

I have the new dryer in a box in the basement, ready to install.

I am curious abou the check valves. There is one built into the dryer on the dryer to wet tank path. Mine was definitely leaking, however it is interrmittant.

I believe by front ride height levelers were somewhat off. The left front was high, I have shortened the rod about 3/8 of an inch. That has helped level the riig. I plan to get under it this weekend and double check the ride height.
