The signs are repeat backups, multiple fixtures draining slowly at once, sewer odor indoors or in the yard, unusually lush or soggy patches of grass over the line’s path, and ground settling or sinkholes above it.
Inside the House
- Multiple fixtures slow or backing up together. A single slow sink is a local clog. When a tub, toilet, and floor drain all misbehave, the shared main is the problem.
- Gurgling from a tub or floor drain when a toilet flushes — air pulled past a partial blockage.
- Sewage backing up into the lowest fixture. That is an emergency and a health hazard.
- Sewer odor indoors that returns after drains are cleaned.
- Repeat clogs — clearing the same line more than once a year means something structural.
Outside — The Signs People Miss
- Unusually green, lush grass in a strip across the yard. That is wastewater fertilizing the lawn, which means the pipe is broken. In a desert climate, a suspiciously healthy patch stands out.
- Soggy ground or standing water along the line’s route.
- Sewer smell outdoors over the lateral.
- Depressions, settling, or sinkholes in the yard or driveway — soil washing into a collapsed section.
- Rodents or insects appearing, which find their way in through broken lines.
What Usually Causes It in Albuquerque
Tree roots. The dominant cause in established neighborhoods. Roots seek moisture and enter at joints or cracks, then grow until they block the line.
Aging pipe. Cast iron and clay, common in pre-1980 housing stock, corrode and separate at joints. Some mid-century homes have Orangeburg pipe, which deforms and collapses.
Ground movement. Soil shifting creates sags and joint separations.
Diagnose Before Repairing
A camera inspection shows the cause and its exact location, which determines whether you need hydrojetting, a spot repair, or replacement.
