The aquaHALT 2X is a battery-operated automatic shut-off valve for a toilet supply line. It runs on 2 AA batteries for up to 5 years, uses two 3/8" water supply hoses, and closes the water at the toilet when its hardwired floor sensor detects a leak. There is no Wi-Fi, no hub, no app and no subscription.
| Specification | Detail |
|---|---|
| Application | Toilet supply line |
| Water connections | Two 3/8" water supply hoses. The existing hose from the toilet tank connects to one side of the device; the included 3/8" x 3/8" hose connects the other side to the wall supply valve. |
| Fitting size | Designed for a 3/8" hose. A toilet with a 1/2" hose connector needs an adapter, which is not supplied. |
| Power | 2 x AA batteries, included |
| Battery life | Up to 5 years |
| Battery indication | 3 LEDs blink = full power, working normally. 2 LEDs blink = reminder to change the batteries, still working normally. 1 LED blinks = low power, and the device turns off after 8 hours. |
| Alert | An audible alert sounds when the sensor detects water or the battery is low. Press "close" to silence it. Left alone, the alert lasts 2 minutes. |
| Controls | POWER button (hold 3 seconds to turn on), plus "open" and "close" buttons |
| Sensor | Hardwired leak detection sensor on a cable, plugged into the sensor connection port on the bottom of the unit |
| Sensor placement | The sensor must touch the flooring to detect water. It can go on the bottom rear wall behind the toilet, or on the bottom of the toilet near the base. The housing has an adhesive pad that mounts to any surface, and the sensor can be removed for cleaning or replacement. |
| Connectivity | None. The device is hardwired and battery operated, with no wireless communication. |
| Mounting | Adhesive pad onto the wall. To remove, twist it left to right or cut the tape with string behind the unit. Do not pull the device straight off the wall. |
| Water exposure | Must not be submersed or installed under water |
| Restoring the water | Dry the sensor, then press "open" to supply water again |
