Check Your Garbage Disposal

The first thing you can do when your kitchen sink is filling up with water is that you should have the check the garbage disposal. When your trash disposal becomes blocked or clogged, water cannot flow through the pipelines, forcing it to back up into the sink.

A garbage disposal can clog due to various reasons like the accumulation of grease or oil, too much food, and hair. Instead of calling the plumber, try fixing it yourself.

How To Fix?

Drain all the water; next, add a paste of vinegar and baking soda down the drain for 15 minutes before running the trash disposal. If this doesn’t help, use degreasing dish soap in the drain and running cold water for 15 minutes, this helps remove the accumulation of oil and grease. 

But if this doesn’t help, you must turn off the disposal. Sometimes, the removals get overheated and automatically turn off. You must restart it as it’ll help. The “on/off” switch for the disposal unit is normally located on the side or bottom of the disposal unit beneath the sink.

Food Can Clog Your Drain

Food and debris are frequent side effects of washing the dishes that can clog your drain.

While little quantity of food into your drain may not be a major worry if you have trash disposal, if you don’t, the material will find its way into your pipelines and cause difficulties if it isn’t cleaned out.

You can also run hot water for a minute or two as it helps unclog the sink. You can use the mixture of baking soda and vinegar paste hack as it melts the accumulation.

You know plunges can also help unclog your sinks. We know you’re aware of it if you’ve used a plunger to unclog and empty your toilets. To get the plunging to function, ensure your sink has at least several inches of stagnant water before plunging for around 30 seconds.

Even if water starts to flow just after the initial plunge, it is advised that you repeat this procedure a few times to dislodge the clog and clean your drain completely; better be safe than sorry.

If these methods fail, consider clearing the obstruction using a drain snake. It is a cost-effective tool that can penetrate pipes to remove build-up.

This procedure is only for clearing blockages that are extremely close to the drain’s surface, which are frequently created by big quantities of food being flushed down the drain at the same time.

If you don’t have trash disposal, a sink strainer is good. It’s simple to clean and will fit into most drains.

Sink strainers provide a filter that protects your sink drain, preventing food from clogging your pipes and clogging your sink strainer.

Dishwasher May Not Be Draining

While it may appear irrelevant, the drainage systems for your dishwasher and sink are the same.

If your dishwasher stopped draining properly, it would most likely affect the drainage of your kitchen sink.

Check whether your kitchen sink typically backs up with water while your dishwasher is functioning. If you answered yes, your dishwasher is almost certainly the source of your problem.

How To Fix?

If your dishwasher isn’t emptying properly, you can attempt a few basic troubleshooting procedures.

Look beneath the sink first. Verify that the drain hose connecting the dishwasher to the drain is free of twists or tangles. It’s as easy as ensuring that water can flow freely down the drain pipe.

If your drain pipe appears to be in good working order, try and run the garbage disposal.

Because many dishwashers drain down the trash disposal, if it’s blocked or jammed with food, making it difficult for the water to get through, this might solve your drainage issue.

Finally, if the dishwasher has stagnant water in it and isn’t draining properly, it may be because your dishwasher’s drain is blocked.

Allow 15 minutes to mix equal amounts of fresh baking soda and vinegar.

Pour boiling water down a drain basket and start your dishwasher on the final rinse after sitting for a while. It should clear any clogs in your dishwasher drain due to this.
