lower size code from “B” to “A” or from “C” to “B” or “A,” then product water flow will not change but the operating
pressure will increase. The High-Pressure Transducer will eventually signal the system to shut down due to excess
pressure to the membrane.
Product Water Abnormalities

Insufficient Product Water Flow

Excessive Product Water Flow

Poor Quality Product Water
The production of the system (product water flow) and the quality of the product water (high quality indicates low
salinity; low quality indicates high salinity) are dependent upon the proper amount of feed water flow and operating
pressure at the RO Membrane Element. Product water flow or quality abnormalities can be the result of pressure
abnormalities described on the previous pages, which are repeated below.
Production abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at sealing
surfaces, or a fouled RO Membrane Element.
Quality abnormalities can also be the result of worn seals, worn O-rings, cracks or damage at sealing surfaces,
or a fouled RO Membrane Element, Feed Water Temperature, and/or feed water salinity.
Lower-Than-Normal Product Water Flow
A blockage in the suction line, resulting in a heavy vacuum reading at the Feed Pump Inlet, will cause the Feed
Pump to cavitate and lead to a reduction of feed water flow and pressure. The Ultra Whisper System is designed
to recover as product water a set percentage of the feed water. Therefore, if the Feed Pump flow decreases due
to cavitation, then the product water flow will decrease accordingly.
Likewise, a blockage in the pre-filtration, resulting in a low pressure reading at the RO Boost Inlet Pressure Gauge,
will restrict the Feed Pump water flow and feed water pressure. Again, the Ultra Whisper System is designed to
recover as product water a set percentage of the feed water. Therefore, if the Feed Pump flow decreases due
to a blockage at the pre-filtration, then the product water flow will decrease accordingly.
A decrease in product water flow can also be caused by a fouled RO Membrane Element. However, as the RO
Membrane Element becomes fouled, the RO Boost Inlet Pressure Gauge will register higher-than-normal pressure
as the system self-adjusts to overcome the fouling. The High-Pressure Transducer will eventually signal the system
to shut down due to excess pressure at the RO Boost Inlet Pressure Gauge when pressure increases to 215 PSI.
Lower-than-normal feed water temperature causes the RO Membrane to require greater operating pressure in
order to maintain the normal product water production. The Ultra Whisper System self-adjusts by increasing the
operating pressure to compensate for lower-than-normal feed water temperature.
A blockage in the product water line will cause lower-than-normal product water flow. The Ultra Whisper System
will attempt to self-adjust the operating pressure to overcome the drop in product water flow caused by a blockage
in the product water line. The High-Pressure Transducer will eventually signal the system to shut down due to
excess pressure at the RO Boost Inlet Pressure Gauge, when the pressure increases above 215 PSI.
Higher-Than-Normal Product Water Flow
Mismatching of system components can cause higher-than-normal product water flow accompanied by increased
operating pressure. The RO Boost Inlet-Pressure Transducer will eventually signal the system to shut down due to
excess pressure greater than 215 PSI at RO Boost Inlet Gauge.
A worn or broken product water O-ring at the end plug inside the high-pressure vessel will allow feed water to
bypass into the product water to produce a greater-than-normal amount of product water. The resulting mixture of
product water and feed water will be of low quality, or high in salinity. This will also show up as lower-than-normal
operating pressure control menu LCD screen.
A crack in the end plug between the feed water port and product water port or a rough surface at the product water
O-ring will also allow feed water to bypass into the product water causing the product water flow to increase. The
resulting mixture of product water and feed water will be of low quality, or high in salinity. This will also show up
as lower-than-normal operating pressure at the control menu LCD screen.
Higher-than-normal feed water temperature causes the RO membrane to require less operating pressure in order
