TROUBLESHOOTING GUIDE
Problem
Cause
Corrective Action
1. Low production rate.
a. Plugged prefilters.
i. Replace prefilters.
b. Low water temperature.
ii. Use higher GPD membrane.
c. Low water pressure (< 40 psi).
iii. Use booster pump OR use
higher GPD membrane.
d. High TDS content (< 1000
ppm).
iv. Use booster pump OR use
higher GPD membrane.
e. Fouled membrane.
v. Replace membrane.
f. Plugged flow restrictor.
vi. Replace flow restrictor
g. Tank bladder lost air charge.
vii. Repressurize bladder to 7 psi
(when empty).
h. Too much pressure in bladder
tank.
viii. Repressurize bladder to 7 psi
(when empty).
i.
Ruptured bladder.
ix. Replace tank.
j.
Backpressure exerted by
the pressurized bladder
tank causes a reduction in
production rate.
x. Use of permeate pump retrofit
kit (PPRFK-DI) eliminates the
back pressure.
2. Zero production rate.
a. Missing flow restrictor.
i. Put flow restrictor in the red
brine line.
b. Dried membrane.
ii. Replace membrane.
c. Plugged flow restrictor.
iii. Replace flow restrictor and
check membrane.
d. Bladder lost air charge.
iv. Repressurize bladder to 7 psi
(when empty).
e. Ruptured bladder.
v. Replace tank.
3. Extremely high
production rate.
a. Ruptured membrane.
i. Replace it.
b. Very high line pressure
(over 80 psi).
ii. Use a pressure reducing valve.
