Sewer Cleaning questions, answered by experts

Sometimes, the drain is just too clogged—thanks, stubborn hair and soap scum. In this case, you’ll need a more powerful drain cleaner than you can DIY safely at home. But this doesn’t mean you have to choose a traditional drain cleaner. 

You can find biodegradable drain cleaners at your local home improvement store or online for those drains that need a little more oomph. 

While on the hunt for a formidable drain cleaner, the best options are non-chemical clog solutions that combine enzymes and bacteria.

It can take anywhere from half an hour to a few hours to fix a main line clog, depending on the cause and severity of it. The job should not take more than a day to complete. Keep in mind that the main line is not the same as your home’s sewer lines (which connect to the main line and run to your house). Your city is responsible for any clogs or damage to the main line itself.

It is safe to flush small amounts of bleach down the toilet. Don’t flush more than ¼ cup of bleach. Instead, consider diluting it and pouring it down the sink drain.

If used correctly and sparingly, root killer shouldn’t damage your pipes. Make sure to follow the instructions on the back of the bottle or the company’s website to avoid any unintended damages. However, when it comes to copper sulfate, it’s better to avoid it. This type of root killer can damage your plumbing and the surrounding environment.

DIY is not recommended due to safety risks and specialized equipment requirements. Hire professionals for effective clearing.
