Water leak detector Ajax WaterStop [1/2] (8EU) ASP Black

The Ajax WaterStop (specifically the 1/2-inch version) is a motorized water shutoff valve designed for remote control and automated security. Its primary function is to automatically turn off the water supply to a building or specific fixture upon receiving a command from an Ajax hub. This command is typically triggered automatically by an alarm from a leak detector (like the LeaksProtect), or manually by a user via the Ajax app. The 1/2-inch size indicates its compatibility with standard plumbing lines of that diameter. It's a key component in an advanced home security system, offering proactive protection against major flood damage.
