Sewer Lines

Main sewer lines and water lines aren’t usually something homeowners think about unless they’re having problems. If you’re researching issues with either of these two less than glamorous but necessary systems, chances are you’re trying to resolve something before the going gets worse. For 90 years, thousands of Northern Virginia residents have chosen Dwyer Plumbing to identify and repair their sewer and water line problems. We’ve seen it all, including century-old terra cotta sewer pipe that read ‘Made in the City of Alexandria.’

Master Plumber Dan Cochran, who has been in the trade since 1978, was a Plumbing Apprenticeship Instructor in Fairfax County for 24 years.

We know our trade. We’re here to help you.

Sewer Line Repair and Replacement

If your sewer line is backing up, draining slowly, or leaking, we can perform a video inspection to identify the cause and the location(s) of the issue(s). More than likely, tree roots have cracked through the line, allowing debris to build up, causing backup. It’s also possible that items washed down the sink or flushed down the toilet have heaped together. Other factors include how well the type of material used (e.g., terra cotta, cast iron, Orangeburg, transite, ABS, PVC) has held up to constant water and roughage, and how well the original installation was performed.

When a relatively young sewer has failed, it was almost certainly improperly installed. Dwyer Plumbing has replaced sewers in many relatively new neighborhoods that had their sewers built incorrectly. In old sewers deterioration or tree roots are the likely cause. Usually located around ten feet below the ground, repairing or replacing a sewer requires serious knowledge, skill, patience, and brawn. Dwyer Plumbing will explain the issues, present you with a DVD of the inspection, answer all of your questions, and send you a written proposal of the work to be performed. Your repair or replacement will be backed by our warranty.

It may be possible to repair or replace your sewer using a trenchless technology known as pipe bursting, which minimizes the amount of digging involved. Dwyer Plumbing provides trenchless solutions in Northern Virginia.
