Sufficient PSI is very important for the correct operation of a reverse osmosis unit. Low water pressure is a leading cause of poor RO system performance. A pressure gauge assures that proper pressure is being supplied. It will also make pressure drops apparent which can tell you that sediment and carbon blocks need to be changed.
This air-filled pressure gauge comes assembled with 1/4″ quick connect fittings for quick easy installation in-line before the RO membrane. This product is designed for use with our saltwater aquarium line of RO systems.
