Signs You Need a Sewer Line Repair: A Guide from A Melbourne Plumber

Your home’s sewer line is vital to keeping your plumbing system running smoothly, but over time, it can develop blockages, cracks, or even collapse.
Knowing the warning signs of sewer line trouble can help you act fast and avoid a messy health hazard and additional costs when reifying the damage.
Jet Plus Plumbing, Melbourne’s trusted plumbing experts, are here to walk you through the top signs that indicate your sewer line may need repair.

Recognising the Warning Signs of a Damaged Sewer Line

When sewer lines start to fail, they often show tell-tale signs that should never be ignored. Here’s what to look out for:

Persistent Sewage Odor Around Your Home

A lingering smell of sewage around your home is a red flag that your sewer line may be compromised. A properly functioning sewer line should be airtight, so any foul smell could indicate cracks or leaks allowing sewer gases to escape. If you detect this odor inside or around your property, call Jet Plus Plumbing for an inspection.

Slow Drains in Multiple Fixtures

One slow drain might be due to a minor blockage, but when multiple fixtures, like sinks, tubs, and toilets, start draining slowly, it often signals a problem in the main sewer line. Blockages, tree roots, or damage to the pipe can restrict water flow throughout your plumbing system. Addressing this issue early can help avoid a full blockage or water backing up and overflowing inside.

Frequent Drain Clogs and Backups

If you’re constantly dealing with drain clogs and backups, it’s more than just a plumbing inconvenience—it’s a warning sign. Recurring blockages often mean there’s a deeper issue in the sewer line. This could be due to invasive tree roots, a buildup of debris, or even a collapsed pipe section. Persistent clogs are best handled by a professional plumber to prevent sewage backup into your home.

Gurgling Noises in Your Pipes

Gurgling sounds coming from your drains, especially after flushing the toilet or running water, indicate trapped air caused by a blockage. This blockage forces air bubbles up through your pipes, creating a gurgling sound. Ignoring this sign could lead to larger issues, including complete blockages and eventual damage to the sewer line.

Super Green Lawn or Sunken Areas in the Yard

If you’ve noticed unusually green patches or sunken spots in your yard, this could indicate a sewer line leak. The additional water and the nutrient rich sewage acts as a fertilizer, causing nearby grass and plants to grow more quickly. Over time, a leak may also cause the ground above the sewer line to sink, leading to uneven areas in your yard.

Higher Water Bills with No Explanation

An unexplained spike in your water bill could mean your sewer line has a leak, causing water to escape before it reaches your fixtures. Although this could also indicate other plumbing leaks, it’s worth having your sewer line inspected if you’ve ruled out other possibilities.

Pest and Insect Infestations

Sewer line cracks or leaks can attract pests such as cockroaches, rodents, and flies, as they’re drawn to the moisture and waste. If you’re suddenly experiencing pest issues alongside other sewer line warning signs, it may be time for a professional inspection.

Causes of Sewer Line Damage

Understanding what causes sewer line problems can help you take preventive measures. Here are the most common reasons sewer lines fail:

  • Tree Root Infiltration: Roots are naturally drawn to the moisture in sewer lines, especially if there are cracks. As they grow, roots can break through pipes, causing blockages and leaks.
  • Aging Pipes: Sewer lines made from clay, cast iron, or other older materials deteriorate over time, increasing the risk of cracks and corrosion.
  • Soil Shifting: Clay soils can cause shifts in the ground, often caused by Melbourne’s weather extremes or construction, can put stress on your sewer line, leading to misalignment or fractures.
  • Grease and Debris Buildup: Over time, oils, fats, and non-flushable items can accumulate, causing clogs that put pressure on the line.

Professional Sewer Line Repair and Replacement Options

When it comes to fixing sewer line problems, Jet Plus Plumbing offers a range of professional solutions:

Frequently Asked Questions

How can I tell if my sewer line needs repair or replacement?


Signs like slow drains, sewage odors, or gurgling sounds in pipes often point to sewer line issues. Minor cracks or isolated blockages can often be repaired, but if the line has significant corrosion, root infiltration, or structural damage, a full replacement may be recommended. A professional inspection from Jet Plus Plumbing can help determine the best solution for your situation.

Is pipe relining as effective as traditional sewer line replacement?

Yes, pipe relining is an excellent, long-lasting solution for many sewer line issues. It’s less invasive than traditional replacement and seals cracks and minor breaks without the need for extensive digging. However, if there’s extensive damage, such as severe misalignment or collapse, a full replacement might be necessary.

What causes tree roots to invade sewer lines, and how can I prevent it?

Tree roots naturally seek out moisture and can infiltrate sewer lines through small cracks, eventually causing major blockages. To prevent root intrusion, have regular inspections and consider pipe relining if there’s early root activity. Jet Plus Plumbing offers preventive maintenance to protect your sewer lines from root damage.
