Common Sink Drain Service Questions

The best place for a kitchen sink drain is the middle of the sink. Most people prefer center drains because they allow for better water and waste drainage, and the center location limits splashing because water flows straight down the drain hole. If the sink drain is too close to the edge of the sink, water can collect and drain too slowly. It can also be easier to clean sinks when the drain is closer to the center since debris is easier to wash down and doesn’t collect along the sides as easily.

There are several types of sink drain stoppers, including pull-out, twist-and-pull, and pop-up. Pull-out sink stoppers can be removed by pulling on the stopper until it comes out of the drain. A twist-and-pull design requires lifting then turning the stopper to lock it in an open position and the opposite action (turning, then pressing down) to close it. A pop-up sink stopper works by pushing down the drain cover to open or close the passageway. 

No, you don’t need to use plumber’s putty to install a sink drain. Other options are available, such as silicone putty or silicone caulk. Plumber’s putty is the traditional method and it’s easier to work with and easier to remove. It doesn’t need to dry before using. Silicone putty should dry before you use the drain.

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

Yes, there are different size sink drains, but a 1 ½-inch-diameter drain is the most common modern drain size. However, some sink drains are 2 inches or 3 inches in diameter. A bathroom sink drain is 1 ¼ inches in diameter, and kitchen sink drainpipes are 1 ½ inches in diameter.
