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?
Cutting a pipe and adding a valve is a really simple thing and should only be expensive to the extent that any plumbing job is expensive.
I would specifically ask for a quality 1/4 turn ball valve - there’s no point in cheaping out on that part when you’re mostly paying for labor. And as long as you’re doing that, you probably want two of them. For the same reason the city doesn’t want you touching theirs, you should have a shutoff that you actually use when you need to do plumbing work in the house, and one before that that you never touch unless it’s an emergency and you can’t shut off the other one.
For a bit more expense, you could consider an automatic shutoff leak detector. I have one called Phyn that keeps track of water usage, tests for pressure drops every night, and detects unusual flow patterns and can automatically shut it off.
