Why Is My RO System Leaking? A Step-by-Step Guide to Finding and Fixing Leaks
Pinpointing the Source and Repairing Leaks in Your Reverse Osmosis System
A leak under your sink can be a homeowner's worst nightmare, but a leaky RO system is often easier to fix than you think. The first step is to turn off the water supply to the system immediately. The main causes of leaks are loose fittings, damaged O-rings, or a cracked housing.
Start by inspecting all connection points. The most common leak points are the quick-connect fittings and the threaded connections at the filter housings. For quick-connect fittings, ensure the tubing is fully inserted. You might need to push the tubing in and then pull it back slightly to create a secure seal. For threaded fittings, a simple tightening may be all that is needed. Be careful not to overtighten, as this can crack the plastic.
If tightening doesn't solve the problem, the issue might be a worn-out O-ring. O-rings are small rubber seals found inside the filter housings and other connection points. Over time, they can become brittle, dry, or cracked, leading to leaks. Turn off the water, unscrew the housing, remove the old O-ring, and lubricate the new one with a food-grade silicone grease before re-installing. Make sure the O-ring is seated correctly in its groove.
Finally, check for hairline cracks in the filter housings or manifold. While less common, a cracked component will require replacement. Contact Great Water Filters Australia for a compatible replacement part. Always use a bucket and towels to contain any water and work slowly to avoid creating new problems.
