Water Pressure Gauge 100 PSI, 1/4" MPT, 2.0" Plastic Dial, Lower Mount, SS Case

Every R.O. system needs a pressure gauge.

Great pressure gauge and exactly what I needed to diagnose a low water issue in my ro system. it ended up being the pressure switch for the booster pump was set wrong and switching on at 10 psi instead of 20 and turning off early at 30 psi instead of 40. While I fixed that problem another came up and I am going to need a larger storage tank. I also used this gauge to find the dynamic pressure of the incoming supply water to the booster pump to fix another issue.
