    Hello.

    My trailer sat for a month while I had truck repairs done. I hooked up yesterday and drove 70 miles with no issue. Last night before I backed into a dock, I dumped the air bags with the RIDE/DUMP valve. After being loaded, moved the valve back to RIDE, and air was leaking out of the short tube under the valve. I was not able to air up the suspension. Any ideas? There has to be a valve somewhere frozen up. I talked to a trailer mechanic, he advised I put some WD40 through the service valve to try and free up any stuck valve, but that did not help.

    Thanks!

    I would think the plunger in the valve is stuck open or at partial travel. Did you try hitting it with a hammer? Sometimes simple solutions work.
