However, a small nick in the O-ring may allow enough Feed Water to mix with the Product Water to cause the
condition without resulting in a noticeable increase in Product Water Flow.
3. Crack in one of the End Plugs within the High Pressure Vessel is allowing Feed Water to mix with Product
Water. This would usually also result in higher than normal Product Water Flow. However, a small crack may
allow enough Feed Water to mix with the Product Water to cause the condition without resulting in a noticeable
increase in Product Water Flow.
4. R.O. Membrane Element is fouled due to normal use and requires cleaning.
5. Salinity Probe has debris on the probe causing the system to read poor water quality. Clean the Salinity Probe
with a toothbrush.
6. Salinity Monitor out of calibration. Test the actual Salinity of the product water using a portable TDS meter. The
system switches from potable water to un-potable water at 800 PPM TDS. If the salinity of the Product Water
is less than 800 PPM TDS then calibrate the Salinity Monitor.
The Water Quality is less than 1000ppm, but the water has a definite salt taste.
1. Blockage or pressure in excess of 55 psi is present in the brine discharge line.
• A blocked brine discharge line causes brine water to mix with product at the Diversion Valve. Flow through
the flow meter will be normal because the flow meter is prior to the 3-way product water diversion valve.
• Ensure that the brine discharge line is free from kinks and that any valves installed in the brine discharge line
are fully open.
2. 3-way Product Water Diversion Valve requires mechanical adjustment or cleaning. Tube Connector fittings
have been over tightened into the valve body causing the adjustment screws to move resulting in seawater
bypass into the product water.
3. Salinity Probe has debris on the probe causing the system to read good water quality. Clean the Salinity Probe
with a toothbrush.
Product Water is leaking from the Product Tubing when the Water Quality is less than 1000ppm.
Blockage or pressure in excess of 55 psi is present in the product outlet line from the system.
• Check all components and check for kinks or closed valves at and after the point of leakage.
• Charcoal Filter element is fouled, replace element
• pH Neutralizer element is fouled, replace element.
• 3-way Product Water Diversion Valve is blocked or inner ports are out of adjustment, adjust inner ports.
There is a Sulfurous odor (rotten eggs) in the product tank.
1. Dirty Pre-Filtration Element.
• Dirty Pre-Filtration Elements allow biological matter to decay. When this biological matter decomposes, sulfur
gas is released as a byproduct.
• Check and replace as necessary Prefiltration and Post Filtration Elements.
2. Charcoal Filter Element requires replacement. Change the Charcoal Filter Element every 3 months.
3. Product Tank is dirty or has biological growth in it. Clean and Chlorinate product tank.
The UV sterilizer is flickering or does not light. (Ultra Violet light will damage skin and eyes. Do not look directly at the
UV lamp)
1. UV lamp is weak due to length of time in use, in excess of 1,000 hours. Replace the UV lamp.
2. The UV ballast is very sensitive to voltage changes. Ensure that the voltage supplied to the UV sterilizer is
within 11.5 VDC to 13 VDC.
3-way Product Water Diversion Valve Abnormalities
When the system is producing “unpotable” water and the Water Quality lamp is illuminated “red” the 3-way Product
Water Diversion Valve coil will not receive voltage from the controller. This allows the 3-way Product Water Diversion
Valve to divert the “unpotable” water to the Brine Discharge.
