How to Repair a Kitchen Sink Drain

Few things are as annoying as a clogged kitchen sink. When something blocks the sink drain to the point that the water does not drain at all, it is time to repair the drain and unclog the pipes. The good news is that is often a simple DIY job and homeowners do not necessarily need the help of a plumber to deal with this situation. However, depending on what is plugging the pipelines, the owners may need to replace the main line and traps. Learning the basics of repairing a kitchen drain can be of help when it comes to getting the kitchen sink working once again.

Methods for Unclogging a Kitchen Sink

There are several approaches for unclogging a kitchen sink that one can try. Usually, homeowners only need a few supplies that are already available in the household. If none of these methods works, homeowners should consider calling a plumber.


Supplies Needed


Cup plunger

Duct tape

Vinegar and baking soda


Baking soda

Rubber gloves

Cable auger

Cable auger

The common materials that cause kitchen sink clogs are food remains, debris, and other substances that have no place in the drain. Regardless of the method, the first thing to do is remove all the visible debris that seems to be blocking the drain.

Using a Plunger

Using a plunger is perhaps the most popular remedy for repairing a sink clog. This method only works when the sink is partially full of water, preferably hot. The cup plunger is more suitable for a kitchen sink, whereas the flange plunger is a better choice for toilets. Users should seal the overflow outlet at the top of the sink using a piece of duct tape. They should then place the plunger right over the drain hole, making sure there is a good seal against the surface of the sink. With quick plunges, the user should then try to clear the obstruction. If the clog clears, one should remove the outlet seal.

Using a Vinegar and Baking Soda Mixture

For this method, one needs a bucket, a pair of rubber gloves, some baking soda, and vinegar. Wearing the rubber gloves, one should first get all the standing water out of the sink with the help of a cup or bowl. Next, one should put a full cup of baking soda into the sink drain and then pour one cup of vinegar over it. Using the stopper in the sink, the user should force the vinegar towards the clog. After five minutes, the clog should be gone. If the clog is still there, one can apply the baking soda and vinegar solution again.

Using a Cable Auger to Unclog a Kitchen Sink

In case the clog does not go away with a plunger or the baking soda and vinegar solution, homeowners should try to solve the problem with the help of a cable auger. To use it, one needs to detach the trap underneath the sink and remove the pipe connecting the trap to the pipe in the wall. Pushing the end of the cable auger is a quick way to catch on the clog. Users can determine where the clog is if the auger meets resistance. After removing the clog, users should check to see whether the water drains well. If it is still slow, using a plunger may be of help.

Repairing a Leaking Kitchen Sink

A puddle of water in the cabinet underneath the sink often means a leaky basket strainer. To repair a leaking sink, replacing the basket strainer is often necessary. To do so, users should first remove the strainer lockout and remove the old strainer from the sink. There should be some putty underneath it, which users should remove with a plastic putty knife before sealing a new basket in the sink. To seal the new basket in the sink, one should opt either for plumber's putty or a non-water based silicone. If a pipe joint is the cause of the leaking, calling in a plumber would be a good idea.

How to Buy Plumbing Supplies on eBay

Purchasing plumbing supplies may take a bit of time, mostly because you have to choose from many tools. This may be daunting especially if you know nothing about sinks. Fortunately, you can find everything in one place by choosing to shop for plumbing supplies oneBay. Whether you are in need of a pipe wrench or a pipe drain kit, a simple search on eBay reveals dozens of models to choose from. Repairing a kitchen sink is not that difficult if you have the right tools and do some research about how to do unclog a sink or repair a leak correctly.
