Booster Pump not working properly

Ashish Patel · Apr 27, 2024

In my new house I have very low water pressure. 35psi. So 2 years ago I ordered a booster pump from Amazon. It was refurbished (big mistake). I only get about 40-45psi with the booster pump and been using it like this for 2 years.

It dawned on me that it may have a valve or something that I could increase psi and it may just be at its lowest setting. When I went online it says the top skrew is to increase the pressure. However the unit did not come with a key.

Does anyone know how to increase water pressure? I am not sure there is a special key

It's a tiny allen wrench - the adjustment is in that little circular tab on top of your pump.

Sorry I missed this, I tried allen key but it didnt work, I may have to revisit this.

I swear if its a simple fix I am going to be really mad at myself for having 45PSI water going in my RO for 2 years. Ugh.

Yea it's pretty simple, I have mine at 90psi and works like a charm for 3+ years.
