[Glenn and Laureen]

I have one valve in the front six pack that I know is leaking (bubble test), so I thought I would buy 2 to start with and see how things go. I did find today that the authorized dealer in Plano, Texas (Hartfiel Automation) has them in stock for less than $50 each (minimum order of 2). My 1984 coach loses supply (house) pressure overnight according to the gauge. Takes about 5 minutes to come up to 120 psi after starting the engine. Brake system is fine. Holds its height for the most part for the past 8 weeks. It was losing height when I first bought it back in April. The air loss seems to be associated with leveling efforts but am not certain of that. The coach has not been used much for the past 10 years and the air system seems to be healing itself somewhat as we use it. Thanks to all who have responded.
