SEWER OR DRAIN DAMAGE AT YOUR PROPERTY?

Address the Problem
Before It Spreads.

A sewer backup, repeated drainage issues, or wastewater leaks may point to pipe damage. Early repair can help restore flow and reduce disruption to your business.

FIX THE PIPE CAUSING THE DRAINAGE PROBLEM

Focus the Repair on the Damaged Section

Licensed Delta technicians clear clogs at the source.

Repeated backups, slow flow, or wastewater problems can point to damage inside a commercial drain or sewer pipe. The location and size of the damage help determine the right sewer & drain repair.

These problems may affect one fixture or appear in several areas that connect to the same line. Where the signs appear can help narrow down which part of the drainage system needs attention.

A repair should address the damaged part of the pipe that is causing the problem. This helps restore a clear path for wastewater and supports normal drainage throughout the affected area.

WHAT CAN DAMAGE COMMERCIAL SEWER AND DRAIN PIPES?

Common Causes of Pipe Damage

Commercial pipes can fail for several reasons. Finding the cause helps your plumber plan the repair around the damaged section.

#1 Most Common

Cracked or Worn Pipes

Age and daily use can weaken sewer pipes over time. Cracks may cause leaks, poor flow, or repeat drainage problems.

Frequently Seen

Shifted Pipe Sections

Ground movement or worn joints can move pipes out of position. This can restrict water flow and lead to repeated backups.

We'll Diagnose It

Tree Root Intrusions

Roots can enter weak points in underground pipes. Tree root intrusions can widen cracks and place added pressure on the line.

DO NOT LET PIPE DAMAGE CAUSE MORE DISRUPTION

One Damaged Line Can Affect Several Areas

Water damage from an untreated plumbing failure

Pipe damage can lead to sewage backups, leaks, and poor drainage. Shared lines may also affect several fixtures or work areas at the same time.

Timely drain repair services or sewer repair services can help address the damaged section before the problem causes more disruption.

Wastewater may stop moving as it should when damage restricts part of a shared line. This can place added pressure on connected drains and make normal plumbing use harder across the property.

As the problem continues, a business may need to limit access to affected washrooms, kitchens, or work areas. Repairing the damaged line can help reduce this impact and return those areas to normal use.

REPAIR THE PIPE OR REPLACE IT?

Choose the Right Approach for the Damaged Pipe

Some pipe problems only affect one section, while wider damage may require a larger repair or replacement. These factors can help guide the decision.

A small damaged section may be suitable for a targeted repair.

Several damaged sections can make repeated drain repairs or sewer repairs less practical.

A pipe with limited wear may be easier to repair than one with damage across several areas.

Repeated failures in the same line may show that the problem extends beyond one section.

The pipe location and available access can affect how the repair work is completed.

REDUCE AVOIDABLE DRAINAGE PROBLEMS

Help Protect Commercial Sewer and Drain Lines

Daily use can place added pressure on a commercial drainage system. Simple practices can reduce avoidable blockages and make new problems easier to notice.

  • Control Grease and Oil: Prevent cooking grease and oil from entering sinks and floor drains. These materials can harden inside pipes and restrict flow.
  • Limit What Gets Flushed: Prevent wipes, paper towels, and other non-flushable waste from entering commercial toilets.
  • Use Drain Screens: Screens can catch food, debris, and other solids before they enter drain lines.
  • Report Clogged Drains: Ask staff to report clogged drains or slow flow before the issue begins affecting other fixtures.
  • Keep Drain Areas Clear: Keep floor drains and cleanouts free from stored items so plumbers can reach them when service is needed.
  • Watch for Sewer Odours: Report persistent sewer smells near drains or fixtures. Strong odours may signal a problem that needs attention.

These practices cannot prevent every pipe failure, but they can reduce avoidable strain and help your team notice changes sooner.

ACT WHEN WARNING SIGNS RETURN

Address Recurring Drainage Problems Early

Repeated backups, slow drainage, wastewater leaks, or sewer odours may point to a new pipe problem. Arrange an assessment when these signs return rather than waiting for several areas to develop the same issue.

Pay attention to whether the same warning signs return after normal plumbing use resumes. A pattern can help show that the issue may involve the pipe rather than a short-term change in drainage.

Early assessment of a recurring problem can help identify the source sooner. It also gives you useful information about when the problem occurs and how often it returns.

TRACK PIPE PROBLEMS OVER TIME

Use Repair History to Plan Future Service

Commercial sewer and drain lines change with age, use, and past damage. Basic records can help you see which areas continue to cause problems.

Note which drain or sewer sections needed work and where plumbers found the damage.

Check whether backups, leaks, or poor flow keep returning in the same part of the property.

Pay closer attention to older sections that have a history of cracks, movement, or repeat repairs.

Repair dates, pipe age, and past problems can give your plumber useful details during a future assessment. This history can also help you decide when another check of the line makes sense.
