SYMPTOMS PROBABLE CAUSE REMEDY
Troubleshooting Ventura Remote Manual Systems
PPM High
•
TDS meter needs calibration
•
Feed Flow or Clark Pump
Problem
•
Membrane fouled or dam-
aged
•
Fouled Prefilters
•
Recalibrate TDS meter or taste test water
until it can be replaced
•
Low product flow, recovery percentage, or
feed pressure can lead to drop in product
water quality. Perform Flow Test &
address flow issue.
•
Clean membrane or consult dealer about
membrane damage.

If system flow (product plus brine) is to
specification, the membrane is clean, the
product flows are consistent with the
system flow, and the water quality is still
not acceptable, then replacement of the
membrane is indicated. By design, high
ppm typically has to do with something
other than the membrane itself.
•
Freshwater flush procedure needs to be
tested and adjusted. PPM of brine
discharge must be below 1000ppm at end
of flush cycle
.
•
Replace filters or run watermaker for an
extended period of time with pressure
relief valve open to rinse.
