- Locate the spot.
- Turn off the main water shut off once you find the leak.
- Dig a trench along the area that shows signs of water leaking.
- Check the line for wear, besides the area of the leak.
- Cut out the spot that leaks; make it at least 6 inches on each side of the leak.
Thereof, can you patch a water line?
An epoxy putty can be applied over the source of the leak to temporarily seal it. Drain the water from the damaged line and ensure that the area to be patched is clean and dry so that the epoxy will properly adhere to the pipe. Tear off enough plumbing epoxy putty to fully cover the surface around the leak.
Likewise, how much does it cost to fix a main water line?
The average cost to replace your water main line is approximately $2,500, depending on the location of your water main and the length of pipe being replaced. If your water main line is far away from your home, then you can expect the cost of your replacement to be closer to $5,000.
You can use PEX for the water line. Sometimes it's good to go up a size since the OD is copper sizing, meaning that the ID is smaller than copper. Or you can also use Poly, which has copper ID size, and a larger OD.
