WARNING SIGNS


Signs You Need a Drain or Sewer Plumber

Drain problems often become more noticeable over time. Recognizing the warning signs early can help reduce the risk of backups and more expensive plumbing repairs.

You may need professional drain or sewer service if you notice:

  • Slow-draining sinks or tubs
  • Frequent drain clogs
  • Multiple drains backing up at the same time
  • Gurgling sounds from drains or toilets
  • Sewage odors inside or outside the property
  • Water backing up into floor drains
  • Standing water near basement drains
  • Toilets that overflow repeatedly
  • Wet areas in your yard near the sewer line
  • Recurring plumbing issues after previous drain cleaning

If several fixtures are affected simultaneously, the issue may involve the main sewer line rather than a single drain.

OUR DIAGNOSIS

How We Diagnose Drain & Sewer Problems

Every plumbing system is different, which is why our team begins each service with a thorough evaluation before recommending repairs.

We first discuss the symptoms you have noticed and inspect the affected plumbing fixtures. Depending on the situation, additional diagnostic methods may include sewer camera inspections, drain testing, and evaluating the condition of your plumbing system.

Camera inspections provide a real-time view inside drain and sewer pipes, allowing our plumbers to identify root intrusion, grease buildup, cracked pipes, collapsed sections, or other hidden problems without unnecessary excavation.

Once the source of the issue has been identified, we explain the findings, discuss available repair options, and provide clear recommendations based on the condition of your plumbing.

Signs a Bathroom Plumbing Issue Needs Professional Attention


Some bathroom plumbing problems may appear minor but can indicate larger issues behind walls or beneath floors. Knowing when to call a professional can help prevent more extensive repairs.

You should schedule plumbing service if you notice:

  • Water leaking around a toilet or sink
  • Repeated drain clogs
  • Low water pressure affecting bathroom fixtures
  • Water stains on walls or ceilings
  • Persistent sewer odors
  • Cracked plumbing fixtures
  • Toilets that continue running after flushing
  • Faucets that drip continuously
  • Mold or mildew around plumbing fixtures
  • Unexplained increases in your water bill

Our plumbers inspect the affected plumbing system, identify the source of the issue, and recommend the most appropriate solution before repairs begin.

Hydrojetting

Hydrojetting uses high-pressure water to remove grease, sludge, mineral buildup, and debris from the inside of drain and sewer pipes. This service is often recommended for recurring clogs, commercial drain systems, and heavily obstructed sewer lines.

Sewer Pipe Replacement

When a sewer pipe has deteriorated beyond repair or has sustained significant damage, replacement may provide the most dependable long-term solution. Our plumbers evaluate the condition of the existing sewer line and explain the available replacement options.

Plumbing Sewer Repair

Not every damaged sewer line requires full replacement. We repair cracks, damaged pipe sections, leaks, and other sewer problems while helping restore reliable wastewater flow.

Sump Pump Plumbing

A properly functioning sump pump helps protect basements and lower levels from water intrusion. We install, repair, and replace sump pumps to help keep your property protected during heavy rainfall and changing groundwater conditions.

Ejector Pump Installation & Repair

Ejector pumps play an important role in properties with below-grade plumbing fixtures such as basement bathrooms or laundry rooms. Our team provides installation, repair, and replacement services to keep wastewater moving safely through your plumbing system.

What can we do for you?

  • How do I know if my problem is a single drain clog or a main sewer line issue?

    A single clogged fixture usually affects only one sink, shower, or toilet. If multiple drains throughout your property are backing up or draining slowly at the same time, the issue may involve the main sewer line.

  • What is the difference between drain cleaning and sewer repair?

    Drain cleaning removes blockages and buildup from plumbing drains. Sewer repair addresses physical damage to the sewer line itself, such as cracks, collapsed sections, leaks, or root intrusion that cannot be resolved through cleaning alone.

  • Do you offer emergency drain and sewer service in Gurnee, IL?

    Yes. C.A.B. Backflow provides emergency plumbing services for urgent drain and sewer problems, including major backups, overflowing drains, and other situations requiring prompt attention.

  • How often should sewer lines be inspected or cleaned?

    The recommended schedule depends on the age of your plumbing system, the condition of the sewer line, and how the property is used. Properties with recurring drain issues, mature trees, or high plumbing usage often benefit from periodic inspections and preventive cleaning.

  • Do you provide written estimates before starting drain or sewer work?

    Yes. After inspecting your plumbing system and identifying the source of the problem, we provide a clear written estimate and explain the recommended repairs before any work begins.
