"The provider came and unclogged the toilet but left me with a toilet that would not stop running. After contacting the provider to let them know they texted me a YouTube video. They said that they were going to come back to complete the repair but did not. I ended up having to hire another company to complete the job."

Sewer Cleaning questions, answered by experts

If the toilet is overflowing but there’s no clog, that’s a sign that the issue is deeper in the system, and plunging may not help. A blockage in your home’s plumbing, the plumbing vent, or even city sewer lines can cause toilets to overflow. The issue could also be the toilet itself if the filler float isn’t set to the correct height or if parts are damaged or worn out.

Bleach isn’t likely to help unclog a sewer line. Bleach isn’t useful in this situation because it won’t dissolve the grime and debris in the clog. Instead, you want to use ingredients that will have a chemical reaction to clear out the buildup, like vinegar or salt and baking soda.

There are a few things that can happen to your sewer system if you don’t fix it. These include rainwater entering it and causing rust and corrosion, dirt and debris leading to blockages, small animals getting stuck inside and clogging your sewer line or entering your home, and shortening the sewer system’s life span. 

Without a cap, nothing prevents toxic and non-toxic gasses like methane and hydrogen sulfide from slowly escaping your sewer system and entering your home and the surrounding atmosphere, resulting in a foul sewer odor throughout your house.

One way to save money on sewer lines is to install a sewer cleanout since it makes sewer line maintenance easier. Keeping up with maintenance is key to reducing the cost of repairs, so be sure to schedule annual plumbing inspections, install drain guards to stop objects from accidentally falling down drains, and only flush human waste and toilet paper to protect your pipes.

In the majority of cases, homeowners insurance will not cover a main sewer line root clog. The reason is that most insurance companies consider tree root damage to sewer lines as common wear and tear, which is also preventable. However, you may be able to buy optional add-on coverage, such as "service line coverage" or "sewer line endorsements," that would protect against root damage to your sewer line.
