There should be a place on the booster pump to use an Allen wrench to dial it in. You don’t want the fast flush valve open at all when making water. Hole in the middle is where mine adjusts with an Allen wrench.Ok, I need to dial back then because it's like 100 psi closed.
btw, the tank felt full for 10 minutes and still wasn't shutting off. So I stopped the system.
That could be why the booster isn’t shutting off also.
