Signs Your Sewer Line Needs Repair

Sewer line problems start small and escalate fast — from slow drains to full sewage backup, foundation damage, and yard flooding. Here are the warning signs every Texas homeowner should know.

Top Warning Signs of Sewer Line Problems

• Multiple slow drains — When every drain in the home is slow simultaneously, the problem is in the main sewer line, not individual drains.
• Sewage odors — Sewer gas has a distinct sulfur smell. If you detect it inside the home or in the yard, the sewer line is cracked or compromised.
• Wet patches in the lawn — Unusually lush, green, or wet areas of the yard above the sewer line path indicate a leak feeding the soil.
• Rodents or insects — Rats and cockroaches enter homes through cracked sewer lines. A sudden infestation can indicate a sewer break underground.
• Foundation cracks — Persistent sewer leaks beneath a slab foundation can wash away soil and cause cracking or settling.
• Sewage backup — Sewage backing up into the lowest drains in the home (floor drain, basement toilet) is a clear sign of a main line blockage or collapse.

Common Causes of Sewer Line Damage in Texas

• Tree root intrusion — the #1 cause in Texas neighborhoods with mature trees
• Grease buildup from years of cooking oil poured down drains
• Pipe corrosion in older homes with clay or cast iron sewer pipes
• Ground shifting and settling common in Texas clay soil
• High-pressure flushing of non-flushable wipes and products
