It’s extremely frustrating when water won’t go down the kitchen sink. The overflow pipe could also sometimes be the culprit. The overflow pipe is sort of a backstop for when there is an excess of water inside the sink. It also helps prevent the sink from overflowing onto the floor. But sometimes, the overflow shaft can be clogged or leak. Sheesh, don’t worry, there are easy solutions to fix all of this!
If you notice water dripping from a wall mount kitchen sink faucet, a leak is occurring. The first thing that you need to do is close the water supply to the sink. The shut-off valves are typically found under the sink. After you’ve turned off the water, look along the pipe for chips or holes. If you find any, you can wrap plumber’s tape around the leak until you can install a new pipe.
Perhaps the biggest overlooked potential issue you could face is the sink accessories for kitchen. That will catch any excess water if the primary drain gets clogged. Was it Drano that you filled your sink with last time right up to the rim? So, obviously, it’s important that the overflow pipe be in good shape and not clogged.

If the water is draining slowly from your sink you have a clogged overflow pipe. You might be able to plunge the clog away. Simply fit the plunger over the overflow hole and give it a few pushes.

Looking to prevent your kitchen sink crossbars from getting clogged? Mind what goes down the drain. Don’t pour grease, coffee grounds or food scraps down the sink because they can block the drain.
