“Section I” System Troubleshooting Guide
D. HIGH PRESSURE GAUGE READING:
Use caution in diagnosing the reading of the High Pressure Gauge. If the gauge is reading low it
may simply be that the Back Pressure Regulator requires adjustment. However, there may be a
problem with the High Pressure Pump or the High Pressure Pump Electric Motor, Back Pressure
Regulator Valve, the High Pressure Gauge, or the R.O. Membrane. A high, full load, amperage
draw at the High Pressure Pump Electric Motor indicates that the High Pressure Pump is applying
pressure within the System.
1. High Pressure Gauge reading is low with normal Brine Discharge Flow Meter reading and low
or no product water flow meter reading:
Back Pressure Regulator requires adjustment to normal System operating pressure.
2. High Pressure Gauge reading is low with normal Brine Discharge Flow Meter reading and
normal product water flow meter reading:
Dirty orifice in the High Pressure Gauge pressure port requires cleaning.
3. High Pressure Gauge reading is low, Brine Discharge Flow Meter reading is low, and Product
Water Flow Meter reading is either normal or low:
High Pressure Pump has a problem within the manifold
Worn Seals are allowing internal bypassing
Broken or stuck valve or valve spring or debris in the valve chamber is allowing internal
bypassing
4. Product water flow meter registers flow and the Salinity Meter Red LED is illuminated:
R.O. Membrane Vessel Assembly is bypassing Feed Water into the Product Water.
The R.O. Membrane Element has a cracked product water tube.
A cracked product water tube is caused by a blockage in the Product Water line.
Ensure that there are no blockages, valves or kinks in this line.
The End Cap Product Water O-Ring is cut or worn.
A worn product water O-Ring allows Feed Water to enter the Product Water.
