Essential Info

DynaQuip Controls, maker of the WaterCop and proven leader in household leak protection, has developed a new way to prevent floods and other water damage in your home. DynaQuip's new WaterCop LeakStop System will detect water leaks and moisture accumulation at a single location and will automatically shut off the water supply to prevent extensive water damage from destroying your home. The WaterCop LeakStop system is designed for a plumbing supply line installation. This should be upstream of the appliance or area you wish to monitor. Place the two sensor probes in an area most likely to be reached by accumulating water if a leak were to occur, most commonly from a water heater. This system is ideal for water heaters which are known for being vulnerable to leaks as they become older. According to the U.S. Department of Energy, It is a fact that nearly 8-million homeowners will replace failing water heaters each year.

The LeakStop system will constantly monitor the user selected areas for moisture and close the valve as soon as moisture is detected. The valve can be manually opened and closed independent of leaks by pushing the open and close soft touch buttons located on the front of the actuator. A ball valve is used to prevent clogging within the valve. Two moisture sensors are attached to the electrical control box for placing around the area or appliance you would like to monitor. When activated, this valve will stay closed until it has been manually reset. Available in a variety of different sizes, these systems pay for themselves after the first activation.

Also available in the following sizes and materials:
Standard 1/2-Inch
Standard 3/4-Inch
Lead-Free 1-Inch
Lead-Free 1/2-Inch
Lead-Free 1 1/4-Inch

Note: Standard sizes are made out of brass. The Lead-Free are compliant with CA, and VT state requirments.
