Express Water – Water Pressure Gauge – Compatible with Reverse Osmosis Filtration Systems, Water Filters – 160 PSI Monitor Includes T-Stem Adapter – Water Pressure Test Gauge for Home

We purchased with our system and it has been very helpful when verifying that the system was running and when it runs. Would definitely recommend.

I love these things...

I like this product actually this is my 2nd order easy to install and the test of the water is really good.

A water pressure gauge is a water pressure gauge. I does let me verify the pressure of the water entering the ROM from the auxiliary pump, the pressure reading on this gauge is approximately 5 psi higher than the reading on the pump gauge itself. It is doing what I wanted it to do, verify the input pressure to the ROM as I understand it 80 psi is best for efficient operation.

This small gauge is an indicator of pressure, but is not very accurate. As instructed, I installed after the lage cartridge filters an into the inlet of the RO filter. It was indicating over 120 lbs. I ordered some stainless glycerin filled gauges and 1/4 tube to 1/4 pipe adapters, so I could add one in place of this gauge. I exchanged them to ensure I was reading correctly and my new gauge showed 75 psi vs the 120 psi and “RED” overpressure indication. So use with caution.
