Leak Preventer

A unique and failure-proof system for stopping undersink water leaks from water treatment devices.

This inexpensive unit detects leaks in water filtration units and shuts off the water supply automatically when a leak occurs. It works with undersink filters and reverse osmosis units. A replaceable, water activated pad within the leak preventer expands to shut off all water going to the water treatment unit when water touches it.

The Watts Leak Protector is very easy to install, and the pads are replaceable. The only tool you'll need to install it is a pair of scissors. Best of all, no batteries or electrical connection are needed. It comes with extra pads and costs less than $20.

The leak protector installs into 1/4" plastic tubing, the inlet tube size of most reverse osmosis units and undersink filters. Adapters are available for 3/8" water supplies. (Call for information about adapters.)

The low price below includes free UPS Ground shipping to your U.S. Address. Shipping to HI and AK is via priority mail and is added to the total.

Green Tube Leak Protector

To install the leak protector, simply attach it to the floor with a single screw at a place where water would likely accumulate in case of a leak, clip the 1/4" tube that supplies water to the filtration unit, and poke the ends of the tube into the protector. When even the smallest amount of water contacts the leak protector, its absorbent pad expands and shuts the inlet water off completely.

This simple device can spare you from the great expense, inconvenience and grief of a water leak.
