Ajax WaterStopWireless MotorisedValve

Ajax WaterStop 25mm White (AJAX-WS-25-W) — wireless motorised ball valve that automatically shuts off the water supply when a leak is detected by an Ajax LeaksProtect sensor.

The Ajax WaterStop installs inline on a water pipe and connects wirelessly to Ajax Hub. When a paired LeaksProtect floor sensor detects water, the Hub commands the WaterStop to close instantly — stopping the leak at the source before water damage spreads. It can also be opened and closed manually from the Ajax app at any time, making it useful for remotely shutting off water when leaving home. The 25mm thread fits standard 25mm (1-inch) pipe fittings commonly used in South African residential and light commercial plumbing. Battery powered, no electrical connection to the pipe required.
