  • In this video, This Old House plumbing and heating expert Richard Trethewey explains how to install a utility sink.


    Steps:

    1. Turn off water
    2. Cut section from existing drain pipe and install a new Wye-fitting
    3. Assemble PVC pipe and fittings for new drain/vent system
    4. Glue drain/vent system to existing vent stack
    5. Rough in the PVC trap assembly
    6. Set the sink into position, inserting its chrome tailpiece into the PVC trap
    7. Tighten the compression nut on the tailpiece to secure the trap
    8. Place plumber's putty under faucet, and install it to the sink deck; tighten nuts from below
    9. Cut into existing hot- and cold-water supply pipes, and solder in tee fittings
    10. Install copper wall anchors to hold new piping in place
    11. Attach flexible supply lines to the hot- and cold-water pipes, and to the faucet
    • Difficulty: Moderate to hard
      Fairly advanced plumbing skills are needed to connect the new sink to the existing water-supply pipes and drain lines.
