I think that would be great Richard. Take a look at the videos of Richard's presentation on air systems for the HWH. Then you should be able to quickly locate the differences and similarities between the systems. We need more insight into the Valid air system!!!!!
Could you post a picture of your Valid six-pack and the solenoids?
Hopefully they are the same as HWH, or similar enough. If the same solenoids then contact Tom, he has rebuild kits for the solenoids.
Thanks for all the feedback.
Stopped by Miami for the experts to solve this one.
I tried replacing the raise valve solenoid while in Santa Barbara but didn't fix problem. That needs a special socket to remove it. Now have one if someone needs to borrow.
Newell found that the Tag Axle valves (yes there are two valves) above the tag axle were not operating. Air was leaking and lifting the tag. Now fixed - good in both travel mode and stationary.
