I have a 75 GPD unit. Water coming out of the tap is only 20 psi and I got 70-100 psi pump. Now the water is coming out at 80 psi. Is that OK to run at that rate? or will it ruin my RO unit. I know optimum psi is 50-65 psi, but I can’t get it any lower than that or can I. Thank for your help.[/quote]
80 psi is more than OK - its great! Where do you have the pump - before the entire system?
Optimum isn’t 50 to 65 - thats just the test conditions the manufacturers use.

Thanks Russ. The pump is before the first stage of the unit. Is that correct? I hear some people say to put the pump before the RO part of the unit.

20 psi seems very low A may need to feed the gerbil :

Yea, I need to start whipping those darn thing to run faster. (no animal harm in this statement). LOL
