Rodi water pressure

[SNAKEMANVET]

My rodi water pressure use to be between 55 and 60 psi, now it is 35 to 38 psi.When I am done running water and pressure drops two of filter canisters drain down half way. What would cause this. Tia

Is your sediment filter due for replacement? You can look into adding a booster pump and possibly a second ro membrane. I did and I'm now making 5 gallons in about 40 minutes

Where is your pressure gauge in the system specifically?

If after prefilters then yes.. its probably time to replace prefilters..
