Air operated dump valuve

[Curt Sprenger]

Hi Jerry,
Did you purchase your coach from Jim & Barbara King?

Is the air leak at the hose to air fitting, or coming from around the cylinder shaft?

Sticking...is usually the paddle that is either binding due to seal distortion, or lack of lubrication. You can purchase the paddles with seals from Dupree products. Use Plumbers lube to lubricate the seal.

Hello,

I purchased "Free Bird" around 3 months ago and final was able to take her out on our maiden voyage. I had all the shocks and air bags replaced and had all the mechanicals check out at ABR (American Bus Repair) located in Alameda, CA. Great place to have work done if you are ever in the area.



The maiden voyage went well. We took her from San Francisco to Lake Tahoe. I was amazed at how many complements we received. I came across one issue when it was time to dump the tanks. Both gray and black dump valves seem to stick. I had to pull (quite hard) on the black round knobs to get them open. I also noticed that after I closed them, the black valve continued to leak air.



My questions is do these valves need to be lubricated so that they don't sick and also, how do I fix the air leak? Or should I just buy new valves? I located power twis-loc valves on dupree products website. is this the correct valve to replace them with?



Any help would be appreciated.
