It can tell you if the pressure is in the acceptable range for the RO membrane, usually 45 PSI to 80 PSI. A gradual decline in pressure can indicate that the pre-filters may be due for a change. This is one of the few ready to install after-market options available, so I don't feel I had much to choose from. Easy to install I do like that fact that it includes the T adapter with the 1/4" quick-connect fittings and the locking clips. This made it easy to snap in place without making any modifications. The ideal place for this gauge if only installing one is at the incoming incoming side of the RO filter Construction and Readability It has a plastic housing and dial face but appears to have a metal stem. I don't really care for the milky plastic. It gives the dial face a slightly cloudy appearance. The gauge is very lightweight due to the plastic construction. It maintains a low profile when installed and doesn't really add any bulk to the RO system. The dial face has a Green Zone for where the water pressure should be (40 PSI to 80 PSI), a Yellow Zone to indicate if the incoming water pressure is too low (under 40 PSI), and a Red Zone to indicate if the water pressure is too high (above 80 PSI). Despite the milky, cloudy dial face, it is relatively easy to read and the water pressure indicator zones are easy to understand. Assessment Overall, the gauge looks as if it was factory installed and originally part of the system. The lightweight plastic housing seems to more or less be of the same quality and durability as the rest of the RO system, tubing and parts. I do wish the plastic dial face was a little less cloudy but I do understand that this was a design choice to keep the plastic for the dial face pliable, flexible and less prone to breakage or cracking.

Items list is needed.** A: Just the gauge. It has a quick connect/disconnect. If you want to measure water pressure, then you will need to devise a way to connect the gauge to the water source. Under my kitchen sink I have connected between the water line from the source to the faucet with a quick connect T, and I use plastic tubing; the type that is ran from a water source to the water inlet on a ice maker on a refrigerator. **Q: can I use to test my faucets and if so will I need to buy additional fittings** A: Dear Valued Customer, Thank you for your interest in Express Water products. With a Feed Water Adapter Valve, 1/4" tubing and a Union Connection Tee you may test your faucet with this Pressure Gauge. Please see below for the part numbers for the additional fittings: PRTFAV3812 PRTFITUT14Q14Q14Q We also recommend using a water pressure gauge with female hose thread to connect to the faucet. Best regards, Express Water Team Toll Free: (800)992-8876 Monday - Friday 10am-5pm PST **Q: Can you please tell me in what section of the filter does the gauge go?** A: The pressure gauge is connected before the membrane with a Stem-Branch tee connection. **Q: I need to fill the gage with glycerin or oil?** A: No. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to install, easy to read color-coded yellow, green and red pressure zones *by R***0 on July 18, 2026* A water pressure gauge is a must have on an under-cabinet RO water filtration system.
