What should water pressure for a BRS RODI System

[reeferboy83]

I recently purchased a 75 gpd 5 stage plus RODI system from BRS. Wondering what the in water pressure should be to properly run the system. I have the pressure guage on there but water coming out of the DI canister is more or less just dripping out. Any suggestions?:thumbs:

I think I found it...65-75 psi

that sounds about right. thats how my Air Water Ice system is

Most are designed to operate at 55 psi. So that would be 75g/day at that rate. If your psi is higher than that, the amount that the unit will provide goes up accordingly. My AWI unit runs at 80-90 psi and produces about 50 gallons every 6 hours even though it's a 100 g/day unit. I'm getting nearly double.

yeah i thought my house pressure was only 65 but the other day i hooked up an inline gauge and im running 105psi........ i can fill a gallon milk jug in less than 10min... its only 2 months old and my membranes are already looking gross... oppps!

Hmm, that's about how long it takes me to fill a gallon (just over one game of Deathmatch in COD MW2 if the kill limit isn't reached, lol) with my 150gpd RO/DI and half the water pressure, so it seems about right.

yeah but mines only a 75gph..

Right, but double the water pressure so double the output. If you put my unit on your house, you could expect to fill that gallon in 5min.

true, but what i saying isnt that bad?? arnt i pretty much forcing the water through the membranes to hard? i feel like its doing more harm than good with higher pressure. i dont think they would set a pressure rating on them just so somthing wouldt blow out? im sure that has something to do with it, but just a thought
