There are a number of different things that can cause the smell of sewer gas to enter your home. It can be caused by drain buildup, sewer blockage, and a number of other factors. You may only be experiencing the smell of sewer gas, or actual sewer gas may be entering your home. Whatever the problem is, there are a number of ways that it can be fixed. Having your drain repaired or cleaned or replacing damaged parts will allow you to get rid of the smell and get your drain back to normal. If these fixes don’t help, talk to a plumber.
The first thing you should try is pouring between one and two quarts of water down your drain. This is often enough to clean out the drain and get rid of the smell.
Use a scrub brush with nylon bristles to clean out the inside of the pipe. After you’ve scrubbed it throughout, pour clean water down the drain to wash everything away.
Once the strainer has soaked, take it out and scrub any remaining grime away. Rinse it off, and put it back on the drain.
If that doesn’t fix the problem, go up on your roof and take a look at your vent pipes. Something like a bird’s nest could be clogging the pipe and blocking sewer gasses in your drain. If you remove it, the gasses will be able to escape.
If the smell is coming from your toilet, you may also want to try shutting off your toilet’s water supply. This can be done with the valve that’s under the water tank. Flush out the tank, and then turn the water back on.
If that isn’t enough to address the problem, there are some additional things you could try. You could shut the water back off and remove the supply line from your tank. You could remove the flange and wax ring and replace any parts that are badly damaged. Take a look at your toilet and see if anything looks like it’s in need of repair.
Even if you’re not a plumber, getting rid of a sewer drain smell can be an very easy task. Try these simple steps and see if they help to resolve the problem. If they don’t, you’ll be able to bring in a professional knowing that you tried everything that you possibly could.
