RO/DI pressure

tlgreve · 03-08-2008, 02:18 PM

I've been wondering, what is the best PSI for RO/DI. I have mine on the main line to my house, and keep it turned down to about 80-90 PSI which is kinda hard to do. Would it work better if I let the psi go up or would that break it?

I use a booster pump to get to 75psi, which is what my manufacturer suggests. Check with the manufacturer to find out for sure.

I found out its 65 PSI! I'm going to invest in a pressure regulator, its hard enough trying to keep it below 100 PSI!

You almost need one for the whole house if it is that high. I had to put one on my house and keep it at 85psi after they added a new water tower and I was looking at enough pressure to blow my house away

actually i wouldnt buy one. I would call my water company and tell them. 100+ PSI is not good for alot of things like Ice makers dishwashers and washing machines. The water company is responsible and needs to put one on your main water line.
Give them a call and tell them you want PSI around 75

Check you manuel on your unit some even say no more then 45 psi.
