Installing a new pop-up sink drain requires a 12-inch adjustable wrench, plumber's putty and a putty knife. The majority of tasks involved in the job can be done by hand without tools. However, adjustable pliers may also be useful for difficult parts.
A bucket can also be useful when replacing a drain to catch any leftover water or debris.
If replacing an existing drain that has become damaged, it may be necessary to take apart the sink's P-trap, which is the curved pipe directly beneath the drain, to recover parts that have fallen off. This may require a pipe wrench or other adjustable wrench, depending on the type of plumbing.
