What Causes Sewer Smell In Bathroom Sink
A bathroom sink that smells like sewer is a common problem, but it can be easily fixed. Here are the top causes of the problem and how to fix them.
Dry P-Trap
The P-trap is a curved pipe under the sink that holds water to create a seal between the sink and the sewer. If the P-trap loses its water, it can let sewer gases escape into the sink. You can fix this problem by running water into the sink until the P-trap is full of water again. You can also try pouring a cup of water down the drain.
Clogged Sink Drain
A clogged sink drain can also cause sewer gases to escape into the sink. The clogging can be caused by hair, soap scum, or other debris. You can fix this problem by using a plunger or drain snake to clear the clog. Once the clog is clear, flush the drain with hot water.
Leaking Sink Drain
A leaking sink drain can allow sewer gases to escape into the sink. Check the drain for any cracks or leaks. If you find a leak, you can use a sealant to fix it. You can also try replacing the drain if it is cracked or damaged. You may need to hire a plumber to install it.
Damaged Sewer Line
A damaged sewer line can also cause sewer gases to escape into the bathroom sink. If you suspect the sewer line is damaged, you should call a plumber to inspect it and make repairs.
Conclusion
If you have a bathroom sink that smells like sewer, try fixing the problem by running water into the sink, checking for clogs, looking for leaks, and inspecting the sewer line. If you can't fix the problem yourself, you should call a plumber.
