Bellied Sewer Line Repair

The belly's signature:

• Clockwork clogs. Blockages recurring at suspiciously regular intervals, because the pool refills with solids at a constant rate.
• Standing water on camera. The diagnostic proof: the camera dips into held water mid-run, and depth marks measure how long and how deep the sag runs.
• Sluggish drainage that cleaning improves only briefly. Jetting empties the pool; the geometry refills it. Improvement is measured in weeks, not years.
• Odors from held waste. A permanent wet reservoir of settling organics announces itself upstream.
• History of soil movement. New construction settling, trench backfill compacting, drought-shrunk clay: bellies have geotechnical parents.

Bellies are also the finding that exposes weak repair advice, because the popular trenchless fix does not apply: a liner follows the host pipe's shape, sag included. This page explains why, and what actually corrects a belly.

The honest repair path:

• Measure the belly first. Camera with locator maps the sag's start, end and depth below grade. The repair excavates exactly this, so precision here is money saved there.
• Excavate and rebed. The correction is physical: expose the sagged section, rebuild compacted bedding to proper slope, and relay or replace the pipe on it. The failed soil under the pipe is the real patient; pipe on bad bedding sags again.
• Why lining is not the fix. CIPP creates a new pipe inside the old geometry; a lined belly is a smoother belly that still pools. Lining earns its keep on cracks and roots elsewhere in the same line, never on the sag itself.
• Verify the grade. Post-repair camera confirms water runs through, not rests in, the corrected section. The belly's defining symptom must be visibly gone.
