I read this entire thread. I have a strange issue with only 1 toilet (1/2 bath) flapper valve that started today. The flapper valve is slapping shut with such velocity that it is splashing water out of the bowl onto the floor. I checked the gauge on the 12v air pump and it was 55 psi. The 110v gauge was around 90 psi. No other air system seems to be having any issue. Thoughts?

I drained the push button valve on my main train the in right front compartment with the 110v pump just a couple of days ago, and opened the right rear wheel well tank valve and let it spray air a few weeks ago. All the other tanks were probably drained at Newell last May during yearly PM, and are overdue. I need to put some effort in figuring out how I am going to crib the coach, so I can get under it, or find a shop that can. I will mess with the 2 tanks I can get to tomorrow and see if that makes a difference.
