Re: Wet tank, no purge valve Reply #25 – May 10, 2021, 01:17:39 pm I didn't take into account the suspension when keying the brakes. Probably having air is the simplest solution after all. I guess having the front tires off the ground has no effect. Quote Selected
Re: Wet tank, no purge valve Reply #26 – May 10, 2021, 01:29:38 pm On our 99' U270, the coupler next to the propane tank is direct to the wet tank with no check valve. I made an adapter hose with a ball valve and male to male coupler and used my portable compressor sitting in the joey bed run off of the inverter to move the coach. Could be used in a pinch to get off the highway in case of air dryer or (in my case) engine air compressor failure. No need to start the engine to work on the air system, except for testing the air brake compressor.DonQuote from: oldguy – May 10, 2021, 12:31:55 pmThanks Chuck I never thought of the tow trucks air already been dried. I put the fitting at the rear of my coach to work on thecoach without having to start the engine. Quote Selected
