Hi all,
I just rebuilt my center bath sequencing valve. Once all re-installed I cracked open the water and it worked perfectly with only a few slight adjustments.
The next day, when flushed, the flapper would open and stay open with no water at all. I shut the water off and went to remove the valve to go through it again to see what I could find. As soon as I released the water supply line to the sequencing valve the flapper shut and the cycle completed.
I went through everything and reinstalled and nothing changed. I've been on the phone with AnnaMaria at Mullaney & Associates (she's awesome!) trying to diagnose as well as talking to Newell service.
AnnaMaria thought that my water pressure at 62 PSI was too high and over powering the air pressure at about 58 psi. I mentioned this to Newell (who said 62 psi is correct and is internally regulated by the headhunter) and he suggested I try using the 12volt pump at 45psi to see if anything changes. Sure enough - Everything worked correctly.
So what's going on here? Toilet works fine on Aux pump but not on Main pump.
I know I can install an in-line regulator, but how did it work previously and why do I have no issue with the rear toilet?
A side note - If you are going to rebuild your sequencing valve opt for the air hose kit from Mullaney & Associates too. They are a lot more flexible and ton's easier to work with than the original super stiff hoses.
