When one or more of the above happens, you could easily spend thousands of dollars on repairs.

Imagine having your water heater on an upper floor, and it breaks, sending all those gallons of water through your foundation, inside your walls, and into your living space. 

That is a nightmare waiting to happen, but now think about living in a condo or apartment, and your water heater explodes, causing your neighbors home to flood.

All of this could be prevented by installing an automatic water shut-off valve.
