This expanding pads will NOT work in our 17mm leak detector fittings.
20mm Replacement Leak Detector Pad
Single-use replacement pads for our 20mm leak detectors. Please note that once a leak detector pad get wet and expands it must be replaced, so you may want to consider getting a few extra pads to keep on hand if the detector goes off. These pads will not fit in our smaller 17mm detectors.
We highly recommend using a leak detector especially if you have a system that may be left attended for long periods of time, such as a cottage, RV or rental unit.
Our leak detectors are completely maintenance free, barring having to replace a pad and doesn't require any batteries or external power. It is easy to installed with the provided screws or adhesive pad and works great with any of our reverse osmosis and ¼” inlet under sink water purifiers.
