Hello,
I am trying to setup a system with my RO/DI to auto flush the TDS creep water for 10 minutes before releasing water to my DI canisters. I am accomplishing this with solenoid valves and my Apex. Its actually working as intended except waste water is being pushed out every few minutes when the system is off (solenoids closed) and under pressure. This also causes the booster pump to kick on when this happens. I thought maybe either of the solenoids where leaking water but the line ends are dry. Water is only coming out of the waste line. It only releases 10-20ml per waste water dump and my pressure gauge does lose pressure for a second then goes back up.
Now when I just run the line from the membrane straight to the DI canisters (like a normal system), bypassing the solenoids it stays pressurized without any waste creeping out.
I thought maybe the Auto-Shutoff valve was going bad so I replaced it. Same issue
Here is a diagram of how I have it all plumbed. Any thoughts?
