RO/DI Pressure..

[Boonjob]

How much pressure is too much pressure running through the system?

My psi is 90-100 at the tap... I can run the rodi @ 90psi.... but it almost seems like it is running to fast as I have a 75gpd membrane but I make way more than that @ 90psi

I should still mention that I get a 232 tds reading at the tap and 0 on the rodi.... So it seems the water is filtering at 90psi, but not sure if i will cause damage to the unit or filters with that much psi.

My pre-filters are marked at 75 psi max operating pressure.

Thought so... I will back my down to 70psi

I just went over any looked at mine the label reads 125 max psi on my pre filters... I wont risk it though I will run @ 70 unless i hear it's ok otherwise.
