Repair Sewer Line questions, answered by experts

Depending on the issue and materials, costs range from $150 to $500.

A two-way cleanout in the sewer line offers access to the sewer line from both directions, which makes it easier to inspect the pipes and clear clogs in the line. Most homes already have a cleanout, but you may want to install a two-way cleanout in your sewer line if your home has frequent plumbing problems, you have an older home that doesn’t already have a cleanout, or you have older pipes and feel like you need more frequent maintenance.

This depends on the location of the blockage. If the blockage is in your home’s system, anywhere in the system, it is your responsibility as a homeowner. Blockages seldom happen because of items or buildup coming from the city, which means it originates in the home. It becomes the city’s responsibility at the exact point your home’s line distributes waste into the city’s system. The exception is if the problem in your home damages the city lines.  

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

In an emergency plumbing situation, taking the time to vet a plumber properly might not be feasible. Instead, it’s helpful to ask the following questions to gauge the experience and expertise of the plumber you’re considering quickly:

  • How many years of experience do you have?

  • Are you licensed and insured?

  • How quickly are you able to get to my property?

You can quickly check some online reviews and the Better Business Bureau (BBB) page for the plumber to get a sense of the quality of service they provide.
