Symptom
Probable Cause
Solution
Flow restrictor clogging
1. Bacteria fouled
2. Raw water excessively
turbid
1. Sanitise system
2. One or more additional
micron
4.
Bad odour in production
water
1. System biologically
contaminated
2. Post-filter exhausted
3. Raw water excessively
turbid
1. Sanitise system
2. Replace post-filters
6.
Low product water pressure
1. Final filter clogged
2. Low air charge in storage
tank
a. Water temperature has
dropped
1. Change final filter
2. Increase tank air charge
a. Same as above
7.
External leaks
1. Tubing not cut square
before inserting into
parker fast and title fitting
2. ‘O’ rings need more
lubricant
a. ‘O’ rings need more
lubricant
3. Fitting loose
1. Cut off 3/8” of tubing and
assemble
2. Replace ‘O’ rings
a. Use silicon based
lubricant on all
‘O’ rings except flush
valve. It requires
Vaseline, Petroleum
Jelly as Lubricant
3. Tighten fitting
8.
Carbon fines in production
water
1. Coming from post-carbon
filter
1. Cycle faucet on/off until
carbon is flushed clean
5.
HELPFUL INFORMATION
RO production is based on water TDS of 1000 ppm NaCL, 80 psl, 77 F. When checking water
quality, ALWAYS check it directly for the membrane element, NOT the RO faucet. To do this, turn off
ball valve on storage tank. Keep RO faucet closed. Disconnect line on storage tank. Wait for 5-10
minutes and check product quality.
Waste water to product ratio should run approximately 3:1. This ratio can vary and is dependant on
TDS, water temperature, raw pressure and membrane performance.
