Water PSI for RO system

Discussion in 'First Time Marijuana Growers' started by gagaganja, Feb 1, 2011.

  1. SO i am looking into picking up a RO system for the end of this grow and so i can start my DWC when this one is over. I have been looking and they all say that they need at least 40psi to work properly. Now i live in a condo on the third floor. so my question is how to i check the psi in my condo. because everything i read tells me to check the pressure at the main or call the water co. since the water bill is in the association and they are impossible to get a hold of i have to figure this out my self. So how can i go about finding the psi.
