WTB: booster pump

[pells61]

I have a new 5 stage RODI unite from BRS for my reef tank I just set up at the local high school. I am running into a problem of low water pressure, it fluctuates from 20 to 40 PSI, and I am worried that this will affect my final product.

Is there anyone out there looking to sell a booster pump that I can afford on my reef club budget?

Thank you all so much for your support as I continue to bring responsible reef keeping to Naperville North High School!

What is the PSI supposed to be, and how does it affect quality?

on the BRS instructions it says to be observant that PSI does not drop near 35 and I swing from 25 to 40 PSI. The instructions read like a drop in pressure to near 35 PSI can compromise membrane function but no specific affects are listed.

it wont hurt it, just not as efficient and fast as with a pump. most people dont have pumps, in chicago the pressure i seen is 25-30 psi. i have one setup and the water is 0 tds under 28 psi. at home i got a pump and have 79 psi on my membrane, i get faster production and hopefully more efficient.
