Rodi w/ booster pump help.

[kchristensen8064]

Hello, I have a BRS 5 stage RODI system with a booster pump, It is supposed to shut itself down when everything is full, and it sort of does... When it gets to the point where all ATO reservoirs are full it shuts off but then pulses on and off until I manually cut power. Has anyone had this happen, and if so what was the fix for it? I have researched possible reasons and still have not come up with a solution. Any help would be greatly appreciated, this is my only piece of equipment that is not running 100% like it should and I'd really like to get it resolved.

Something leaking letting the back pressure drop.

That's one of the things I've looked into, but I can't find any leaks. Do you have any advice on how to try to narrow down where a leak might be?

Replace the check valve on your permeate tube. It is leaking (but the leak is internal - you'd not see it dripping anywhere except out the concentrate tube).

I have replaced this already, but I'll change it again and see if it makes a difference.
