RO Membrane ASOV bad?

[Johnd651]

Was getting ready to head out and noticed my RODI booster pump was running, but we haven't used any water today.

Went down to look at it and noticed it was really hot to the touch. I unplugged it to let it cool off. Once I unplugged it, it sounds like water is running through the restrictor. It is a 150gpd system, so its a 1100 CC fast flush restrictor. I tried working the valve, and the flow slightly changed out of the waste line. At this point I am thinking its the ASOV, but I wasnt sure if the restrictors go bad as well?

Just glad I caught it before I burned up the booster pump. Worried about how much damage I might have done to the booster pump.

Better get a new one. Aren’t they supposed to be on a timer?

Mine has never been on a timer. I have an inline pressure switch that when it hits 60 psi shuts the pump off.

Could it be air in the line? I forgot I replaced whole home filter.

Looks like it was air
