I have an older apt with old galvanized piping. The main water shutoff valve and main line at the bldg is old and corroded. The main line from the water company meter at the street goes under the concrete driveway about 30'. I need to replace the valve and maybe all the piping from the meter to the main valve. How is the best way to do this? Below are some options and would appreciate any opinions on the best and most economical way to do the job - the property is located in Southern Calif.
- Cut the concrete and dig out the entire line line and replace with new pipe and valve.
- Bore or tunnel out a new place for the line to go and push the line through the tunnel. I have heard of this but do not know how practical it is.
- Just replace the valve at the end. How do you attach the new valve to the old pipe while maintaining strength - assuming part of the buried pipe is strong.
- Any other ideas about new techniques that are being used.
Can copper pipe be used for the buried part of the line?
I would appreciate any advice on the above. Thanks, Rick
