Hi David,

Sorry for the delayed help. I was on a air leak mission to help another guru who desperately needed it.

Ok, first things first. On the ping tank in the passenger rear well is a check valve. It allows air from the tank, and therefore the supply side of the air system, to flow towards the 12V pump. It does not allow air from the 12V pump to flow to the entire house system. That way the 12V pump is trying to air up the suspension. There are some piping connections at the 12v pump along with a regulator that provide air to the potties, doors, and slide seals. WARNING WARNING WARNING. I have seen this done about as many different ways as different Newells I have looked at. So when looking at yours think concepts and principles of how the air is flowing. Showing you a picture of mine may do you more harm than good.

There are some air leaks that are really difficult to locate. Areas to check are the shuttle valve solenoids that control the air dumps on the waste tank. The air cylinder for the dump mechanism can also leak internally.

The doors are a real puzzle to find the valve. Look at the carpeted ceiling areas adjacent to pocket doors to gain access.

Take a look at the blowoff valve on the bottom of the big air drier located in the tag drive wheel well.

Take a look at the push pull valve to open the generator. Also try to gain access to where the gen slide is located and listen with the sniffer.

Is it safe to assume that you are NOT leaving the HWH leveling system in AUTO level when parked.

The water separator bowls at the 120V pump and at the rear six pack are KNOWN gremlins.
