When a new sink is purchased, the new sink drain needs to be installed so that water can drain from the basin into the drain outlet. This process also takes place when the existing sink and drainpipes are being replaced. Homeowners should learn how to install a bathroom sink drain, so the project can be done quickly and easily when it becomes necessary.
You will need:
Step 1: If replacing existing pipes, measure them and purchase new pipes of the same dimension.
Step 2: Turn off the water supply to the sink.
Step 3: If pipes are being replaced, remove the washers and plastic nuts connecting the traps and pipes. Locate the hole at the bottom of the sink bowl and insert the drain section into it. Screw this piece on using the washer from the drainpipe kit and the pipe wrench.
Step 4: Connect the straight section of pipe included in the kit to the washer. Use the pipe wrench to help with this task.
Step 5: Connect the J pipe, also referred to as a trap, to the straight section of pipe, using the pipe wrench.
Step 6: Connect the remaining bent pipe from the kit to the J pipe and the drain outlet contained in the wall.
Step 7: Pour some water down the drain and check for leaks. Ensure that washers are secure and tighten connections as necessary.
Step 8: Install faucets separately, if necessary.
Step 9: Turn on the water supply to the sink.
