I bought a 6 stage RO/DI unit from BRS, and the 150GPD upgrade. The homes water pressure in Kent is only 35psi on the ro/di unit. I took a pressure gauge and tested the house, and onlt get 45psi. The unit says that it needs 60psi to work, however it is producing RO/DI water as I type this. What can I do to up the pressure in the home, and should I shut the unit off due to low RO pressure?
