Finding a puddle of water under your RO water purifier is a common frustration for many homeowners. A leaking purifier not only wastes water but can also damage your kitchen cabinetry or walls. Fortunately, most leaks are simple to diagnose and resolve once you know what to look for.
Top 5 Causes of RO Water Leakage:
- Loose Elbow Connectors: The blue or white push-fit elbows connecting the water pipes to filter cartridges can loosen over time due to high pressure. Swapping the lock clips or replacing the elbow connector usually stops the leak immediately.
- Cracked Filter O-Rings: Inside each filter housing (pre-filter bowl or membrane housing), there is a rubber ring (O-ring) that forms a watertight seal. If this ring dries out, cracks, or gets misaligned during a filter swap, water will drip from the cap threads.
- Damaged RO Tubing: The plastic pipes connecting components can develop microscopic cracks, pinholes, or split ends. Cutting off the split end and reinserting the tube solves this.
- Booster Pump Head Leakage: The diaphragm in the head of the booster pump can rupture, causing water to drip from the seam between the pump motor and the pump head.
- Choked Waste Water Line: If the flow restrictor (FR) or reject tube gets blocked by scale, pressure builds up inside the housing, forcing water to leak out of the weak spots.
If you experience any of these issues, turn off the water inlet and power supply immediately and call our helpline for a technician visit.
