The RO membrane is the costliest part a water purifier service firm replaces regularly, and the one customers question most. Doing an RO membrane change on evidence (TDS readings) and recording it builds trust and sets up the next reminder.
Signs an RO membrane change is due
- Product water TDS has risen and stays high after pre-filters are replaced
- Flow of purified water has dropped sharply
- Water tastes different, and the pre-filters are not the cause
- The maker's interval for this water quality has passed
The process
- Record feed and product TDS before work.
- Check and change pre-filters (sediment, carbon) if due.
- If product TDS is still high, replace the membrane with the correct model.
- Flush as per the maker, then re-test product TDS.
- Record the date, part, readings and next due date; show the customer the before and after readings.
Pricing the visit
Price the membrane, labour and travel, and show them on the job card. For AMC customers, say in the plan whether the membrane is included; see the RO AMC quotation format.
Make the next one a reminder, not a complaint
Record the change on the purifier's record and set the next due date from the readings and the maker's guidance. Use the filter change reminder system and the RO service report format for the visit.
Each purifier with its history
ServicePilot keeps each purifier as an asset on the customer's record, with parts used on every job, and the Service Due list shows customers due for a filter or membrane change.
