-Turn off main water supply (or supply to that pipe, if a more local shutoff is available.) Then saw out the damaged portion.

- Cut an equal size piece of new PVC pipe. Dry fitnew pipe and two connector couplings to be sure the fit is good. Remove new pieces.

- For each connection (each old pipe joined with a coupling, each new pipe end joined with one of those couplings):

  1. Sand cut ends lightly to remove any burring that would interfere with a tight seal.
  2. Swab outside of pipe and inside of coupling with PVC primer (usually brightly colored, such as purple or orange.)
  3. Swab the outside side of pipe and inside of coupling with PVC cement (glue).
  4. Firmly push pipe halfway into coupling, twisting slightly to ensure a good seal.

- Let dry briefly before restoring water flow.

- Once water is restored, check new fittings for leaks.
