Spot Free Water R.O System

[stampedecarwash]

Hello, I have a Coleman Hanna Super Savor for my wand wash. Noticed sometimes while the R.O system making Spot Free water the pump pressure drops from about 190psi (which supposed to be as per the note on the system) to about 100 psi. The floats showing the GPM of Product and Reject water drops quite bit aswell. I thought something is wrong so tried to stop the pump by disconnecting the float sensor on top of the Spot Free Water Tank (As if its sending a signal that the tank is full so the pump stops). But after disconnecting the float sensor nothing happened and the pump kept running for few more minutes and stopped by itself. Then I connected everything back and everything seems to be working as normal and the quality of water product water in the tank is like always about 10 ppm.
Question: Is it normal for the R.O System to reduce the pressure to 100psi sometimes as if its trying to clean itself???

It's normal, there's a flush solenoid that opens and drops the pressure.

Any idea of how often this is supposed to be happening, or if there is a way to manually flush the system? I never seem to catch mine in action.

in the last year or so I noticed it only two times...but I'm sure it happens more than that...yes you wont notice it very often...

I've never watched to see when it flushes. The system is controlled by a PLC so there's no way to check other than watch for it.
