RODI won't exceed 40 psi

[paintballer768]

Hi all,

Normally, I can control the psi going into my rodi unit by simply opening or closing the faucet handle. Yesterday I replaced the sediment filter in one of the cylinders for the first time, and now it won't exceed 40 psi no matter how much I open the faucet handle.

For reference, I'm using this rodi system: BRS 4 Stage Value RO/DI System - 75GPD - Bulk Reef Supply

I can hear what sounds like vibration or possibly sucking air from the top-view ball value area, but cannot figure out what the cause may be. Has anyone else experienced this?

Thank you

Adding a picture to clarify what I mean by "ball valve area":

Nevermind, in the time it took to write this, it worked its way up to a more normal range.

My unit always runs around 65 psi. As the filters age the psi will drop.

Don't try to control pressure or temperature, always fully open the cold water supply and never use hot or warm water. Membranes love pressure so
give it all you have.
