TROUBLESHOOTING GUIDE:
1.
Low production rate:
a. plugged prefilters.
i. Replace prefilters.
b. low water temperature
ii. Warm feed water OR use higher GPD membrane.
c. low line pressure.
iii. Use booster pump OR use higher GPD membrane.
d. high TDS content.
iv. Use booster pump OR use higher GPD membrane.
e. fouled membrane.
v. Replace membrane to restore flux.
f. plugged flow restrictor.
vi. Replace flow restrictor & membrane.
2.
Zero production rate:
a. Missing flow restrictor.
i. Install flow restrictor in the red line.
b. Dried RO membrane.
ii. Try to restore flux by soaking in rubbing alcohol OR
replace the membrane.
c. Plugged flow restrictor.
iii. Replace flow restrictor and replace the membrane.
d. Flush Valve is open.
iv. Close Flush Valve.
3.
Extremely high production rate:
a. Ruptured membrane.
i. Replace membrane.
b. Very high line pressure (> 80 psi).
ii. Use a pressure regulator.
4.
Pressure gauge does not register pressure when the system is “ON”
a. Missing flow restrictor.
i. Put flow restrictor in the red line.
b. Pressure gauge screwed in too far.
ii. Unscrew pressure gauge one-half turn and retest.
c. Plugged pressure gauge orifice.
iii. Clean orifice with a needle.
d. Defective pressure gauge.
iv. Replace it.
5.
Low deionization cartridge life:
a. Defective membrane.
i. Replace it.
b. Low pressure (< 40 psi).
ii. Use booster pump.
c. High CO2 levels in water (> 5 ppm)
iii. Aerate RO product water.
d. High TDS in feed water (> 1000 ppm). iv. NO EASY SOLUTION.
e. Bad or faulty DI cartridge.
v. Replace DI cartridge.
f. High pH tap water (>9.0).
vi. Acidify feed water to the RO membrane to improve
its rejection.
