rodi pressure question

[Meshmez]

I have a BRS 5 stage 75gpd rodi system, just got my booster pump set up... my question is how much pressure is too much? the minimum i can get the pump to do is 70psi. is there any disadvantage to running it higher?

 

[willybub]

my booster pump runs at 100psi to supply my bulk tank

i just didnt know if there was a optimal or max pressure to run through the ro/di system at.

Some have a max pressure, mine says do not exceed 75PSI.. my water pressure is normally at 60 PSI so it's all good..

Dudes at BRS said 100PSI is fine for their units. My water pressure for my RODI is over 100PSI and it still doing fine.

i dont think the units have problems, but i think the clear housing are rated at like 125 or 150 which you shouldnt exceed or you will blow out the housings.
but 100 isnt a problem for operation pressure.

thanks everyone!

Be careful here!

This is a perfect example of why I cringe everytime I hear someone say the only difference in brands of RODI systems is the filers. NOT TRUE!!!

For example, there is a very widely used brand of clear housings where the wholesaler indicates they should not be used over 60 psi, and the clear sumps should be changed annually. Again - this is a brand of housings that is used on many many systems out there.

There are other clear housings which are of better construction and have a 125 psi limit. As a consumer you'll have no idea which brand is used on your system. Solution: be careful about the RODI vendor you use!
