Underground plumbing drain lines are responsible for carrying wastewater and sewage away from your home safely and efficiently. They run beneath your foundation and slab, working constantly to keep your plumbing system flowing the way it should. When these lines become cracked, clogged, or misaligned, waste can no longer move through the system as intended.
Backed-up drain lines can create pressure on your plumbing system, allow sewage to seep into the surrounding soil, and cause persistent odors and moisture issues inside your home. Left unaddressed, a failing underground drain line puts your foundation, your indoor air quality, and your overall plumbing system at risk.
