Occasional clogs in the sink, tub, or shower drains are a fact of life. They are usually caused by localized clogs in the drain trap or branch drain for a single fixture. However, if you have several fixtures that are draining slowly or not draining at all, the problem may be in the main drain or sewer line in your home.
Here’s how to unclog a sink using several methods:
- Use a plunger.
- Try a sink auger.
- Remove the drain trap to auger the branch drain.
- Use a mild, non-toxic, and biodegradable drain cleaner.
- Try a baking soda and vinegar solution.
Read on for details and tips for each method.
Try Using Boiling Water to Fix a Clogged Sink
Most clogs in sinks and tubs are due to a combination of hair, grease, soap residue, and tepid water that are trapped in the drain trap right below the drain opening. If you have metal pipes, you can try to loosen the clog with hot waterโvery hot. Pouring a pot of boiling water directly down the drain into the trap may dissolve the clog, especially if it consists of soap scum or grease. Hot tap water won’t do the trickโit has to be boiling water.
Boil a gallon of water in a large pot or tea kettle. Something that will allow you to pour directly into the drain, such as a tea kettle, is best. When it’s at a rolling boil, carefully carry it over to the clogged sink. Pour the water slowly into the drain. Be careful not to splash the water, as this can lead to burns. Give it a few minutes to dissolve the clog. If it doesn’t work, proceed to the steps below.
Warning
Do not pour the boiling water directly into a porcelain sink, but only down the drain. And do not use boiling water if you have plastic (PVC) pipes since water hotter than 140 degrees Fahrenheit can soften some types of PVC pipe. For plastic pipes, attempt to clear the clog using a plunger.
