My city water is coming in at 91 psi. I installed this restrictor and the pressure didn’t change at first. After a couple minutes of watching my pressure gauge at the RO input the pressure instantly dropped to 70 psi. It’s been a few days after the install and has remained at 70 psi.

For the water purifier that I installed, the pressure had to be regulated or the filter would leak and blow up because my pressure was too high.

Using for my RO system. Incoming PSI to my house is 110. This scaled it down to something managable for my system. No leaks.
