Double Kitchen Sink Backing Up Into Each Other

Backing Up Kitchen Sinks Into Each Other?

It can be inconvenient and frustrating to run your garbage disposal only to have the wastewater and food scraps back up from the other sink bowl. However, why would two kitchen sinks back up into each other?

What you may not realize is that even if you have two kitchen sinks, they share the same drainpipe. The two kitchen sink bowl drains are connected to the main sink drainpipe by a tee pipe.

This means that if the main sink drainpipe becomes clogged, wastewater from both sinks will be unable to drain. As a result, the water in the sink bowl being used will back up into the other sink bowl.

A clog in the main sink drainpipe causes double kitchen sinks to back up into each other. Pour half a cup of baking soda and 1 cup of white vinegar down the drain, then follow with a gallon of boiling water after 15 minutes to fix the problem. Remove and clean the P-trap instead.

The problem will begin as a slow draining sink before the two sinks begin to back up into each other. This is due to the fact that the clog is usually only partial. Remember to disconnect and clean the tee that connects the garbage disposal to the drain pipe when unclogging a double kitchen sink with a garbage disposal. That is where the majority of the gunk collects.

How to Unclog a Backing Up Double Kitchen Sink on Both Sides

The good news is that unclogging a kitchen sink is a simple task that rarely requires the assistance of a plumber.

There are also several ways to go about it, so you can pick the one that suits you best.

The three best ways to unclog a double kitchen sink that backs up to the other side are as follows:

1. Plunge

A plunger is a simple but effective tool for unclogging drains. However, if you want to dislodge the clog quickly and easily, you must use the proper technique.

To effectively plunge, you must have some standing water inside the sink. You can’t plunge into a sink that’s empty. The water creates the pressure needed to dislodge the clog.

Because we’ve established that the clog is in the main sink drainpipe and thus not specific to any sink bowl, it makes no difference which bowl you plunge from. You will, however, require two plungers and an extra set of hands.

You have successfully unclogged the sink if it drains properly. If, on the other hand, water continues to back up from the opposite side of the sink, you’ll need to try something different.

2. Make use of Baking Soda and Vinegar

Baking soda and vinegar have been used successfully to unclog drains on numerous occasions. When vinegar (a weak acid) and baking soda (an alkali) are combined, they produce a fizzing reaction that dissolves the clog.
A gallon of boiling water works wonders for breaking up the clog even further. Pouring a gallon of boiling water (or just hot) down your kitchen sink drain, even if it is not clogged, is an excellent way to prevent clogs.

3. Disassemble and clean the P-trap

Although most people rarely use it, this is a quick and effective method for unclogging a kitchen sink. It also does not require any prior plumbing experience.

If your double kitchen sink is backing up into the other side, the clog is most likely inside the P-trap. The problem can be solved by removing and cleaning the P-trap.

The three methods listed above are the most effective for naturally unclogging kitchen sinks. I would not recommend using chemical drain cleaners, particularly acids or bleach. Get in contact with plumb center exeter for more informations.
