theishkid Posted November 27, 2016 Share Posted November 27, 2016 I have a Bulk Reef Supply 5 Stage RO/DI unit and I'm trying to figure out if I'm using the flush valve properly... You open it up to let water flow over the membrane and and flush out the sediment, then close it back up after a few minutes to start making more water correct? But my understanding was that when you open up the flush valve the pressure should go up a little bit. And when you close it to start making water again, the pressure should drop down to normal. As of right now when mine is closed and making water the PSI is about 60. And when open it drops down to 50 PSI when going over the membrane. Is this correct or is my valve installed backwards or something? Water always comes out of the DI line in either case, usually when the valve is open it's just a little bit less. Is this normal? Open flushing the membrane at 50 PSI. Closed making water at 60 PSI. And here's just one of the valve in the closed making water position. Link to comment
Admonition Posted November 27, 2016 Share Posted November 27, 2016 When you open it up and flush it the PSI drops. When you close it and 'make' your water the PSI goes up. So your unit is working just fine Link to comment
