rodi automatic shut off

[sphelps]

You need to find out what the pressure is after the membrane where the pressure switch is tied into. The gauge reads the pressure before the membrane and therefore isn't relative to what the switch is actually getting. Tie in the pressure gauge temporarily at the same point the switch ties in.

Also is there a flow restrictor and check valve on the waste line?

I think I have the check valve on the waste line but not 100% sure been moving too many fittings lately. I'll move the gauge over as well and see what I have on that line. And I'll post up that info.
Thanks

Here is a flow diagram with a pressure switch and a solenoid.

Because you have some of your plumbing behind and underneath the pic, I cannot figure out where everything is.
Hope the link helps

Ok I check all the fittings and moved the check valve/restrictor to the waste line as well as the pressure gauge to the rodi water. I have 40-42 psi with the float valve held up. I'm starting to think there is something wrone with the ro canister. Even when I hook it up to the waste line it still will not shut off and that one has 50 psi when closed.
I'm starting to think I need to buy a new one that is already set up, and sell this one. I feel that I am running out of time to be playing with this one.
There are only 2 lines that you could not see 1 comes from the filters and heads up and the other leaves the ro and goes down to the di filter and then it's on to the tank.
