You step away for just a minute. Suddenly, you hear gurgling noises. When you look back into the room, you know you’re in trouble. The kitchen sink is filling up with water. What do you do first?
If you’re lucky, you catch the sink overflowing before it floods the entire kitchen. Still, you need to stop the water, drain the sink and get things cleaned up. We can help.
Taking Control of a Flooded Kitchen Sink
Different appliances and all the sinks, showers and toilets in your home operate on one interconnected plumbing system. A clog in this network is the most common reason for water backing up in the kitchen sink.
Quickly figure out what might be draining somewhere in the house. If it’s the dishwasher or washing machine, turn it off. If there aren’t any appliances running, shut off your home’s main water valve.
5 Steps to Unclog a Kitchen Sink Filled With Standing Water
Bail as much water as you can from the sink, and assess the damage. If things look bad, call your insurance agent and start the water damage claims process. Try one of these five tips for unclogging the kitchen sink, but be patient. It might take several tries or a combination of techniques to get the job done.
1. Check the Disposal
Run enough water down the disposal to allow for safe operation. Turn it on, and let the water and disposal run for a few minutes. If the flooded sink begins to drain, you know you’ve dislodged a clog in the disposal line.
2. Try Boiling Water
Bring a large pot of water to a full boil. Wear oven mitts to protect your hands as you pour the hot water directly into the clogged sink drain. If you don’t get results right away, let standing water in the sink cool, and then try again.
Power Tip: Pour half a cup of table salt into the drain before dousing it with boiling water.
3. Use Simple Chemistry
Fizz out the clog by pouring a cup of baking soda down the drain followed by a cup of white vinegar. After the mixture bubbles up and settles down, top it off with a pot of hot water.
4. Grab the Plunger
If none of the above tricks work, it’s time to use the plunger. Make sure there’s enough water in the sink to cover the plunger bell and ensure a tight seal. Minimize splashing by working the plunger with a firm, steady action.
Power Tip: If you’re unclogging a double kitchen sink, seal off the drain that’s clear before plunging the clogged side.
5. Clean the P-Trap
Put a bucket under the curved P-trap pipe below the clogged sink. Detach the trap by removing its coupling nuts, and clean it out with a stiff bottle brush or wire coat hanger.
Power Tip: After cleaning the P-trap, run a plumber’s snake through the exposed stub pipe to clear any clogs that might be further down in the system.
Cleaning Up After Kitchen Sink Flooding
Once you unclog the overflowing sink, water damage needs to taken care of as quickly as possible. Otherwise, you risk long-term damage to floors, walls and cabinets as well as a mold outbreak under the kitchen sink.
• Thoroughly mop floors, pantries and cabinets.
• Clean all surfaces with a mild detergent.
• Position fans to cross-ventilate and dry out the room.
• Leave cabinet and pantry doors open during the drying process.
The Dangers of Sewage Backing Up in the Kitchen Sink
While most kitchen sink flooding results from clogs in your home’s plumbing system, damaged sewer lines can cause serious problems. If you think you’re dealing with sewage backing up in the kitchen sink, locate the sewer clean-out line behind the house.
Using an adjustable wrench, remove the line’s clean-out cap to release water pressure. Be careful because this will send sewage out of the pipe and into the yard. Never try to handle dangerous sewage cleanup by yourself. Bring in a restoration contractor who specializes in biohazard-certified cleanup.
