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 & membrane.
g. tank bladder lost air charge.
vii. Repressurize bladder to 7 psi (when empty).
h. too much pressure in bladder tank.
viii. Repressure bladder to 7 psi (when empty).
i. ruptured bladder.
ix. Replace tank.
j. back pressure 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 yellow brine line.
b. dried membrane.
ii. Replace membrane.
c. plugged flow restrictor.
iii. Replace flow restrictor and 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.
