What to Do While You Wait for Emergency Sewer Help

  • Stop using water: Pause toilets, showers, sinks, laundry, and dishwashers to reduce backup pressure.
  • Keep people and pets away: Sewage exposure can be unsafe. Keep kids and pets out of the affected area.
  • Avoid electrical hazards: If water is near outlets or electrical equipment, avoid the area and shut off power only if it’s safe.
  • Ventilate if possible: Open windows in the affected area when it’s safe to do so.
  • Use protective gear if cleanup is unavoidable: Rubber gloves, rubber boots, and eye protection reduce exposure risk.

Important: If you smell gas or suspect a gas leak, leave the building and call your gas utility or 911 first.

Common Emergency Sewer Problems We Handle in Denver

Sewage Backing Up Into a Shower, Tub, or Floor Drain

This often points to a deeper main line restriction and needs urgent attention to reduce damage and exposure risk.

Multiple Drains Clogged at the Same Time

When more than one fixture is affected, the blockage is often deeper than a single drain line.

Basement Backups After Laundry or Dishwasher Use

If wastewater rises when other fixtures drain, the system may be operating against a restriction.

Gurgling Toilets and Bubbling Drains

Gurgling can happen when air is trapped by a restriction and the system cannot drain normally.

Recurring Main Line Backups

If the line clears but backs up again, the root cause is often still in the pipe and needs proof-based diagnosis.

What Causes Emergency Sewer Backups

Root intrusion: Roots can enter aging sewer lines and create repeat blockages.

Heavy buildup: Grease, sludge, soap residue, and mineral buildup can narrow the pipe and catch debris.

Non-flushables: Wipes and other debris can create tough clogs that return quickly.

Pipe damage: Cracks, offsets, low spots, or collapsed sections can trap waste and cause chronic backups.

Emergency Sewer Service Should Be Fast, Calm, and Proof-based

In a sewer emergency, you need three things:

  • Stop the backup and reduce damage risk
  • Identify the real cause (not just the symptom)
  • Fix it in a way that reduces repeat backups

We stabilize the situation first, then confirm whether the line needs clearing, jetting, repair, trenchless work, or replacement planning.

Before Any Excavation: Call 811 for Utility Locates
