RODI

When I first set this up with a 75gpd water upgrade kit, it produced 1:1 good/waste water ratio. I probably made 500 gallons.

Now its doing 1:2. Wasting a lot of water. What can I do? Do I need to replace something? Water pressure is 60 psi. The valve is completely shut off.

Was pressure always 60

My RODI is more efficient at its 85psi limit.

Maybe check the membranes; one of them, perhaps the primary is a bit depleted?
