Sink Not Draining: Air Lock in Drainpipe
When a sink is not draining properly, it can be a major inconvenience. One of the possible causes of a clogged sink is an air lock in the drainpipe. An air lock occurs when air gets trapped in the drainpipe, creating a blockage that prevents water from flowing through.
There are a few things that can cause an air lock in a drainpipe. One common cause is a clog in the drainpipe. When a clog forms, it can block the flow of water and air, creating an air lock. Another common cause of an air lock is a faulty vent pipe. The vent pipe is a pipe that allows air to enter the drainpipe, which helps to prevent air locks from forming. If the vent pipe is clogged or damaged, it can prevent air from entering the drainpipe, which can lead to an air lock.
There are a few things that you can do to try to fix an air lock in a drainpipe. One simple solution is to try pouring a pot of boiling water down the drain. The boiling water can help to break up the clog and dissolve any buildup that may be causing the air lock. Another option is to use a plunger to try to dislodge the clog. If you are using a plunger, be sure to cover the overflow hole with a wet rag to create a seal. You can also try using a drain snake to try to clear the clog. If you are unable to clear the clog yourself, you may need to call a plumber for assistance.
Once the air lock has been cleared, you should be able to use your sink normally again. However, it is important to note that air locks can sometimes reoccur, especially if the clog that caused the air lock was not completely removed. If you find that your sink is not draining properly again, you may need to repeat the steps above to clear the air lock.
Here are some additional tips for preventing air locks from forming in your drainpipes:
- Keep your drains free of debris. This means regularly removing hair, soap scum, and other buildup from your drains.
- Make sure that your vent pipe is clear and unobstructed. If you have any trees or shrubs near your home, be sure to trim them back so that they do not block the vent pipe.
- If you have a garbage disposal, be sure to run it regularly to keep it clear of clogs.
By following these tips, you can help to prevent air locks from forming in your drainpipes and keep your sink draining properly.
