This is an odd one. The only whole house shut off is on the city side of my meter and the person from public works I talked to said only the city could operate it and if it were to break while I operated it I could be held financially liable.
Does anyone know of a ballpark price to get a plumber to install on my side of the meter?
There is a pretty slick automatic water shut off that you can put wireless sensors at places like outside of a sump pump well or in a tray under the hot water heater. If the sensors detect water, they tell the valve to shut. I think they run a couple grand all in, but it is cheaper than having to gut your basement because the sump pump failed during a downpour.
There are several. I have one as I mentioned in my comment: it’s called a Phyn Plus. It works with and without sensors. I have some in strategic places like under the water heater.
It actually caught a leak, although it wasn’t from the plumbing. It was rain getting into the chimney and dripping into a puddle in the boiler room that set off one of the sensors. I like the cable-style sensor they have – it’s like a 4-foot-long headphone cord, but the whole length is a water sensor, so if any part gets wet it goes off.
