    Installing a kitchen sink drain

  1. 1

    Start by removing the old drain parts. You can do this by starting with the p-trap using the channel lock pliers. Place a small bucket under the p-trap to catch any water that may spill when you remove the p-trap from the pipe. If you have a dishwasher, be sure to disconnect the hose attached to the drain. Simply loosen the nut on the clamp holding the hose in place. Continue unscrewing the remaining nuts on the drain pipes using the channel lock pliers.

    Again, using the channel locks, remove the old basket from the sink by loosening the nut on the bottom of the sink. Pull the old basket strainer through the hole and remove any old putty from the sink.

    Before placing basket through the hole of the sink, apply some plumber's putty around the underside lip of the basket. Pull the basket through the hole and then screw the nuts in place to tighten the basket to sink, flattening the putty in place to create a seal. Some of the putty may ooze into the sink. If this happens, just wipe it away.

    Tighten new parts in place in the same way the old parts were removed.

    Be sure to remember to reconnect the dishwasher hose back into place before using the sink or dishwasher. Make sure that all connections are snug. Do not over-tighten as this may cause a leak. Also remember that connections should be snug, but with a very small degree of looseness to them.
