When I turn the vavle near the water meter it seems that it is not shutting off the water, as I must've turned it 40 times. Is there a second valve in the house? I looked above the drop down ceiling where I thought it might be and the pipe just shot straight back into furnace room. The valve that seems to not shut and the meter are at front house in basement. The furnace room is at back. Where could it be if there is a 2nd?
Yes the old main valve not shutting off completely. We often run into this during renovations.
Best to call a plumber in as their probably is no second main shuttoff except at you water tank to stop hot water. You can quickly attatch a sharkbite with a suttoff attatched but will have to be done while you have water still running. We use white bread to stop water from running while we sodder new valves on then the bread dissolves shortly after.

In the front of your house generally in the front by the sidewalk is a valve from the city called a CC. A plumber or your water provider will be able to turn it off and on at that point. Its something I would call a plumber on as its a quick fix but not a homeowner one due to tools needed to do it right.
I have never tried the bread trick sounds interesting but I would avoid putting foreign objects in a potable water line.
Often a valve such as the main shut off inside the house because it has not been operated often will not close completely due to corrosion. there is also a main curb stop shut off at the edge of your property if you are on town/municipal water supply. you can have your local water company shut this for you or most plumbers will have a curb stop wrench to do so. Once shut down replacing the main shut off valve inside your home is simple either by DIY or local handyman or plumber.
