Ro booster pump

[jdpeters]

I’m only getting 55 psi, id like to increase that. I assumed it was me needing to change out either sediment, carbon block or RO membrane. None of that increased id, I swore I was getting 60 psi at one point.

I have a Brs 4 stage, which item should I consider?

You can do the aquatec booster pump, BRS sells them.
However, I'm pretty happy with the AquaticLife Smart Buddie
