When a sewer main clogs once, the best course of action is to call a sewer main cleaning service and have the line professionally cleared. Since there's no pattern of problems, only the immediate issue needs to be resolved. If your sewer main clogs regularly, though, you'll want to take action to address the repeated clogging. Here's what you might do.
Have Your Sewer Main Repaired or Replaced
The most expensive options is to have your sewer main repaired or replaced. This will fix the problem as a new main will be installed, but it'll cost a lot because your current sewer main will need to be dug up. If you elect to go this route, be prepared to pay for:
- The machinery and labor required to dig up your current sewer main
- The materials needed for a new sewer main
- The machinery and labor required to install the new sewer main
- The plants and labor needed to replace any landscaping that had to be dug up
All in all, you'll probably end up paying thousands of dollars. CostHelper reports that the average sewer main replacement costs between $3,000 and $6,000, and complex replacements can run much more -- as much as $25,000.
Have a Clean-Out Installed
Depending on where the clog occurs, you may be able to have a clean-out installed on your sewer main.
A clean-out is an access point that's installed on a sewer main. Its purpose is specifically to make cleaning out clogs much easier. With a clean-out, you may be able to use a plumbing snake to reach clogs in the sewer main yourself. All you need to do is open the clean-out, insert the snake and unclog the back-up. After you're done, the snake can be removed and the clean-out closed up.
This solution requires a smaller upfront investment, and it'll give you the ability to remedy future clogs yourself. In the long run, it could save you a lot on plumbing costs if your sewer main clogs frequently.
Schedule a Periodic Clean-Out
If you aren't the do-it-yourself type, you can schedule preventative clean-outs with a sewer main cleaning service.
Rather than waiting until your sewer main clogs and making an emergency call, schedule a time for them to come and clear out your sewer main. As long as they come slightly more frequently than your sewer main clogs, these preventative clean-outs should stop your sewer main from backing up.
