Automate your mains water for emergencies

Overflowing bathtubs, leaking washing machines or defects to gas and water pipelines – severe damage to the home can occur at almost any time and cause immense costs. POPP Flow Stop 2works to prevent it from ever happening.

Flow Stop 2 is a motor operated shut-off controller for automatic flow stop of gas and water pipes. It is equipped with Z-Wave technology. This means it is particularly suitable for use in smart homes.Even installation is child’s play. The POPP Flow Stop 2 is delivered completely including valve control/motor, power supply, mounting and Quick Start Guide and is easy to assembly on the existing ball stop valve. In doing so, all usual pipe standards, including ½ ” and ¾“, are possible. On this occasion no pipes must be dismantled or even water must be drained. That way the installation is normally done in 5-10 minutes.

POPP Flow Stop 2is driven by a motor and closes the ball valve mechanically. Even though the Motor requires only 12 Volt (1A), it has a high power output as well as high torque, which reliably closes the ball valve in just 10 seconds. Also a manual closing of valve is easily possible in case of power failure – thanks to the clutch release bearing.

Once Flow Stop 2 is added to a smart home gateway via Z-Wave, the stop valve can be operated via any PC, notebook, smartphone or tablet. Additionally, in the event of leaking gas or water the smart home gateway – when combined with sensors – is able to stop a further inflow automatically and thus protects against more extensive damage and further danger.

POPP Flow Stop 2is a good piece of security for the intelligent home defending from nasty surprises and high costs due to gas and water damages.

As a leak prevention tool, POPP Flow Stop 2 works best when your automation system has a Z-Wave water sensor attached to it. The water sensor detects that a leak is happening, and your Z-Wave software instructs Flow Stop 2 to turn off your mains' water connexion. We (naturally) recommend the Z-Wave water sensor from our sister company Aeotec, which you can learn more about at that link.
