Automatic Sensors Stop Washing Machine Floods

Washing machine floods due to a bad valve or a ruptured water hose are frequent enough that an automatic sensor is a good investment. Here's how to install one.

Stop washing machine floods

Water does more damage to homes every year than fire. And the washing machine is one common source of water catastrophes. When supply hoses rupture or valves inside the machine go bad, water flows freely until someone shuts it off. Several devices are available online or at plumbing supply stores that shut off the water automatically. The one shown here (called FloodStop) takes less than 10 minutes to install. Here's how it works: When the sensor detects water on the floor, it sends a signal to the control unit, which sounds a screeching alarm and automatically closes the valves.

Shutoff systems for water heaters and other appliances are also available. To install the valves, you have to unscrew the supply hoses, so this is a good time to replace your old rubber hoses with safer, steel-sheathed hoses.

I installed a system similar to this one several years ago after I finished off the basement in our beautiful old farmhouse. With 1800 sq. feet to work with there was room to build my wife the laundry room and arts & crafts rooms that she wanted, and the sportsman's den and family rooms that I wanted. I spent a whole winter and mucho denero finishing off that basement and to protect that investment I had installed water s\detection systems not only in the laundry room but one that protected the hot water heater and another one for the general plumbing system as well. The one on the hot water heater save me big bucks last winter when it started leaking while we were away for the weekend. I modified mine to not only shut off the water but the electricity and gas to the heater as well.
