There are plenty of culprits for a kitchen sink backing up, but the reason is usually because of a clog. With backed up kitchen sinks, it can be difficult to find the source of the clog on your own. In many cases, you might have to inspect the drain connections within the walls.
Possible Cause: Clogged Sink. A clog in the sink itself is one of the more common reasons for water to back up. Using sink cleaners and snakes in the drain can often unclog the sink drain. You can also schedule a professional drain cleaning to see if you can unclog the sink drain.
Pour one cup of fresh baking soda down the drain, followed by one cup of white vinegar. Place a rubber stopper or other sink hole cover over the drain opening. Wait 15 minutes to allow the vinegar and baking soda to unclog your drain, Then take out the drain cover and run hot tap water down the drain to clear the clog.
Water Backing Up: Water coming back up from the shower, tub, or sink drains, especially when you flush the toilet, is a clear indicator of a clog in your sewer line. Wet Floor Drains: If the floor drain in your laundry room or basement is wet or overflowing, this could be an early sign of a sewer backup.
Slow drains may not always be due to clogs.
Plumbing vents, soap buildup, and garbage disposal malfunctions are among the most common culprits.
Blocked Main Drain Line
This line is what connects your home to either the septic system or the city sewer line. If too much sludge or debris makes its way into the main drain line, it can affect plumbing throughout your entire home, including the kitchen sink.
The first thing you should do is turn off the water supply to the main line. Next, remove all debris from the drain. Then, pour hot water down the drain until the clog is loosened. If the clog still won't budge, call a professional.
Backflow occurs for one of two reasons, either back pressure or back siphonage. Back pressure is the result of a higher pressure in the system than in its supply, i.e. the system pressure has been increased by some means. This may occur in unvented heating systems, where thermal expansion increases the pressure.
You will likely pay around $350 to $650 to have a plumber unclog a main sewer line unless you have complications like serious damage to the line.
all you need to do is mix around 1/3 cup of baking soda with 1/3 cup of vinegar in a cup. You'll have to immediately pour this solution down the drain to be effective. Rinse with hot water after about an hour.
If your sink won't hold water, chances are the stopper isn't seating securely over the drain hole, or there could be leakage due to a bad stopper gasket.
The P-trap is the U-shaped pipe under your sink that generally contains water to block odors and gases from your sewage. It also serves as a catch tray for items that may fall into your sink that should not have. Your kitchen sink will start to gurgle when your pipes are clogged, causing the P-trap to trap air.
This blockage can cause water to back up into the sink when the disposal is turned on. Installation and Alignment Issues: Improper installation or misalignment of the garbage disposal and drain line can disrupt the smooth flow of water and waste, leading to drainage problems and backups.

Leaking from the Backflow Prevention Device
Backflow prevention devices rely on seals to create a watertight barrier. Over time, these seals can wear out, crack, or become damaged, leading to leaks.
What can cause a backflow? There are two main causes of backflow: backsiphonage and backpressure. Backsiphonage can occur when there is a loss of water pressure in the system due to a break in the main line or a heavy demand such as a firefighting effort.
Clogs, clogs, clogs: Recurring clogs can be one reason that sewer lines keep backing up. You'll experience persistent clogs if things like oil, grease, hair, “flushable” wipes, or other items keep entering your drains and sewer line. The good news is that this is one of the easiest problems to fix.
So, when you notice water backing up through the plug hole instead of smoothly draining away, it's a cause for concern. This unexpected issue is a clear sign of a problem in your drainage system, most likely a stubborn blockage.
No, Drano® is not recommended to clear a clogged sewer line. Bottle unclogging solutions are designed for minor clogs and are not strong enough to break up more extensive sewer line blockages.
Turn Off the Water.
Turn off the water at the main valve to prevent any more water from filling up the already backed-up pipes. Turning off the water is also the best way to stop sewage from coming up the shower drain.
Fixes for Low or No Water Pressure in Bathroom Sink
Remove and clean the faucet aerator thoroughly, or replace it with a new one. Remove and clean the flow restrictor, increase the size of the flow restrictor hole, or remove it entirely and replace the aerator without replacing the flow restrictor.
