How to change water main valve with water on?
The main shutoff valve in my basement is leaking out the top of the valve and I want to replace it,the problem is the main valve/curbstop outside is broken and will not shutoff. The city I live in says from my house to the main across the street is my problem and my main is a 1950s lead line so if I dig, the whole line under the street from the corporate shutoff to my house has to be replaced at my exspense 3,000to5,000 dollars.Is it possible to replace valve in basement with water on?how much pressure does the main have? Any help will be greatly appreciated,thank you
