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 chance it’s “outside” in some sort of deep box but that seems unlikely unless you are in the south.
You need a plumber unfortunately and if you really don’t have one it might be a grand or more. Schedule with water company to turn it off at the street, cut, add a good modern shutoff in a useful location (which might require changing layout) and so on.
Good luck, but I would not do it myself based on the comments so far. Just fyi.
Don’t use a ball valve unless you can trust your self to always do it slowly the shock to the system if you slam it closed can break old lines. The proper valve to install is a globe valve.
