Oil-Filled Pressure Gauge

Oil-Filled Pressure Gauge; from 0-150 PSI; 1/4" MPT

Knowing your exact water pressure is essential to proper troubleshooting of an Reverse Osmosis (RO) System. At higher pressures, RO systems produce more water, faster. At low, pressures the reverse is true. If pressure is too low, the RO may not produce any product water at all or will fail to shut-down.

Water pressure is not the same as flow. Water pressure can not be determined by looking at the flow of water from a faucet. Many homes that had low pressure, when tested, appeared to be perfectly normal when looking at the flow of from the faucet.
