Membranes should be changed out every three months or as needed, whichever occurs first
0. Membranes and filters that fall under this
0. Carbon filter
0. Prefilters (sediment filter)
0. Polishing filters
0. Standard membrane
0. Vent filter on tank
0. Membrane change out shall be verified using a TDS meter. If the rejection of output water TDS drops below 80%, the membrane must be changed out.
Tank
1. Tank shall be inspected weekly for content leaks.
1. Tank pressure shall be checked semi annually
1. Pressure check must, at a minimum occur when the vessel is empty or near empty
1. Additional checks can be conducted at various levels.
1. Float calibration shall be verified annually (low level float, high level float, etc.)
1. Controls shall be visually checked monthly to ensure there are no programming error present, the screen and buttons are fully functional and readings are being recorded
Pumps

3. Test RO feed water TDS, chlorine and water hardness content
3. Check and set pretreatment filter and water softener clocks
3. Check all controls
3. Check pump pressures
3. Log RO pump pressure, flow rate and temperature
3. Test RO product water TDS and log flow rates
3. Test RO reject water TDS and log flow rates
3. Log Recovery %
3. Log Rejection %
3. Log pressure gauge readings.
3. Check salt/ chemical tank levels and add as needed. Repair any minor leaks.
Any additional maintenance recommendations as required by the manufacturer.
