Pressure gauge on RO/DI

[ZANYMASTER]

What is an idea number it should be at without the booster pump being I have low pressure in my building?

 

[emmanuel]

Me and a friend both get 42-45 psi in astoria on the first floor

 

[ZANYMASTER]

So,is that a good number?

I'm thinking anywhere between 40-60psi is fine without. Any lower... you definitely want a booster pump.

psi

I get between 65-70 psi on the norm.

im going to min 50 max 80 so ill prob try to run it about 60 65 psi

My 75gpd brs unit said it should be 50 for optimum performance I think thats just so you get the rated 75gpd

+1. I had only 20psi living in high rise apartments with a booster pump I full a 32gal bucket at 82psi in a matter of 4 hours ..

Agree with skene.

Nelson, optimum psi for an efficient production is 80 psi. Lower than about 65 psi and you will certainly see a drop off. I've seen systems that produce zero RO/DI water at 40 psi. It just wasn't enough pressure to push through the filters and membrane. The path of least resistance is through the waste line, and that's where the water went.

If your water pressure is below 55 psi, you will absolutely benefit from a booster pump (actually, even if your pressure is below about 65 psi you'd benefit).

Can it run on lower psi? Sure, not efficiently though.

on the fourth floor, my psi is at 45-55...no problems
