Ajax WaterStop Wireless Water Shut-Off Valve 1/2" — White

Ajax WaterStop is a wireless shutoff valve that closes the water supply as soon as a leak is detected, so a split hose or a failed fitting does not turn into a flooded floor. It suits homes, offices and tenancies where water damage would be costly to put right. This version is sized for 1/2" (DN 15) pipework in a white finish.

An electric actuator drives the bundled RuB ball valve shut within 7 seconds of an alarm from a LeaksProtect Jeweller or a third-party leak detector, with up to 8.5 N·m of torque behind it. The valve reports to the hub over the Jeweller and Wings radio protocols, and it can also close on a schedule, on an alarm, or when the system is armed or disarmed. Everything is configurable from the Ajax apps, and a mechanical button and lever give manual control on site.
