The cleanout is usually a 4-inch-diameter pipe with a screw cap that has a square knob or indentation on the top. It's most likely going to be popping up from the ground outside your home between the foundation and the street. The cleanout might also be on the side of the home, closest to the bathroom.,
When you flush the toilet, water backs up into or comes up in the tub or shower. When your sewer line is clogged, the water can't go down the drain. Instead, it flows back up the pipes and comes out at the lowest point — usually the shower drain.
If you see used water from the toilet backing up into shower or tub drains though, that's a sign of a clogged sewer main. Since something is blocking the wastewater, it has no other choice but to back up. Since your toilet is set higher, the water is more likely to rise out of the lower tub or shower drain.Jul 10, 2020
If more than one of these drains is slow-moving, is gurgling, has a foul smell, or has water backing up, that is signs of a clogged sewer line. Slow-flowing water is an indication that your main sewer line may have become clogged.
For indoor main drains, you will likely find the cleanout in a bathroom or utility area. When dealing with a bathroom location, check the floor near the toilet. In this scenario, it might be a pipe protruding from the floor or it might be flush mounted into the floor. These main drains tend to have a threaded plug.
If you have a home that was built before 1978, you may not have a sewer line cleanout. Once you find the cleanout, screw off or pull off the cap. If the sewer water is flowing up and out of the pipe or standing in the pipe, this confirms you have a sewer line clog.
Driving a screwdriver at an angle into the outer edge of the cap. Then tapping it with a hammer to pry it open little by little. Directly tapping the fitting on top of the cap with small sledgehammer to get a little bit of movement. Again, if you accidentally break the cap, they are cheap to replace.May 31, 2016
