If you’re experiencing ongoing issues with your plumbing, you may need a sewer main replacement or repair. If you’re building a new home, you may need a sewer main installed to channel wastewater to your septic tank or the city’s water treatment plant. Here are five sewer questions to prepare for talking with a pro. 

1. What best describes your sewer need?

In most cases, when you notice plumbing issues across multiple fixtures in your home, it’s an indicator of a sewer main problem, not a clogged drain. Be ready to share the list of issues you’re experiencing with your sewer system, such as overflows, foul odors, and slow drains. Other signs of sewer line problems include foundation cracks and pest infestations. 

Describing the issues can help your local sewer pro understand the problem and the tools and materials needed to fix it. For example, they might inspect the line with a sewer camera or bring a sewer auger to clean it. 

2. When do you need this work done?

You should call a professional immediately if you notice sewage backup, foul odors, or frequent slow drains and toilet backups. Contact a local sewer pro to have the issue inspected and fixed. Other signs of a sewer main problem include gurgling noises in your pipes, mold in your walls, slow drains, and basement flooding. Delaying a sewer main repair can lead to expensive water damage, sewage leakage, and foundation cracks. 

3. How can a pro help with your sewer pipe?

If you're experiencing ongoing plumbing problems, you​​ may have a blockage, tree root intrusion, or a broken or corroded sewer line. A sewer pro may inspect, clean, or repair your sewer pipe. If installing a new sewer main, a pro needs to excavate, grade the land, and install the new pipe. Contact a sewer pro early in the build process, and be sure they coordinate with your general contractor. 

4. What other plumbing do you need help with? 

If you have other plumbing needs, such as changing a fixture or fixing a bathroom leak, have a pro take a look while they’re on-site. It’s wise to capitalize on other plumbing projects at the same time to save on costs.

5. What is your budget for the sewer main?

The cost to install a sewer line ranges from $1,425 to $5,760, depending on the length, labor costs in your area, and local requirements to connect with the city’s water and sewer system. If your sewer lines are experiencing clogs or other issues, plan for sewer line replacement or repair costs between $1,400 and $4,100.
