"Came and looked at - ordered parts than returned 3 weeks later to complete the repairs.  Toilet was unusable during that time but that was our choice as we had other bathrooms. I am sure that had that been our only bathroom they would have made temporary fixes to the toilet.  I would use them again."

Sewer Cleaning questions, answered by experts

With a one-way cleanout, you can access your sewer line from one direction. Depending on the way it curves, a plumber can either access the side of the pipe that goes into your home or the side that goes to your yard. On the other hand, two-way cleanouts allow pros to access both sides of the sewer line, thanks to their dual-pipe design (they’re usually U-shaped).

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.

A two-way cleanout can help if there’s already a clog, but the best strategy to prevent one is by not rinsing grease, oil, or fat down your drains, not flushing or rinsing coffee grounds or egg shells down your drains, flushing only human waste and toilet paper (so no diapers, period products, bathroom wipes, or paper towels), and using drain guards on all of your drains.

Most commercial liquid drain cleaners work in 15 to 30 minutes. Consult the label on the bottle for additional instructions or time suggestions to prevent damage to your drainpipes. Alternative solutions such as baking soda, salt, white vinegar, and/or boiling water can take longer since they are less harsh than liquid drain cleaners.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.
