Main water shut off valve for house leaking, city water valve buried in driveway
The control valve for water in the house is behind the wall in our basement bathroom. Basement was renovated by previous people and apparently it's against bylaw for the control valve to not be exposed. The valve is old and corroded.
Anyway, I shut it off to do something else in the house and then turned it back on and it started dripping right where the handle meets the stem. Dripping enough to fill a glass in half hour. Now water is no longer dripping and actually running down the pipe to the concrete floor behind the wall.
Called Halton Region and they take responsibility for these fixes even though it's in our house. Guy came over in less than hour. Should be a 5 minute fix but he couldn't find the city water valve outside. He checked couple neighbours and theirs are on the driveway. Knocked on our neighbour's door and she confirms that like 10 years ago the her husband told the contractors doing the new driveway not to bury the city water valve. Well they did it anyway, as did multiple other neighbours (she's been here 30 years).
The region guys had a map and said our city valve and the neighbour's to the other side should be almost side by side in the lawn along our property line. Well that it was the city told them to do in the 70s when these houses were being built. Guy said builders don't always follow their requests.
So anyway, region guys are waiting for some other guy to bring a machine that can map out the pipes to confirm the valve is where they believe it is under my driveway. They used two different readers that get strongest signal right on this spot and they've since marked it with a blue paint, and this is parallel to where they are on my two neighbours to the left. If the other guy confirms their findings, well WE gotta chisel away that spot on my driveway. After that, region guys can shut off the water and do the fix in my basement.
My father in law can patch the driveway afterwards and leave the valve exposed. But in the meantime, who is going to dig up the spot? Are there are emergency contractors and handy guys that do this kind of thing on weekends? How much might they charge? Or should we rent tool from HD that does this? Does this kind of thing seem easy enough?
The water will continue to leak overnight and forever until we solve this problem. I can lay down old towels on floor and kind of soak up most of it maybe but since it's running on the floor I'm sure some will end up all along the concrete behind my drywall. Region guy says he's seen such bad leaks in house and not able to find city valve outside in timely manner that they've had to shut down water for the whole street.
