Annual Drain Maintenance Sutherland Shire

Some of the most common signs of a blocked drain include:

• Water draining slowly from sinks, showers or baths.
• Toilets that are slow to flush or rise higher than normal before emptying.
• Gurgling sounds coming from drains or toilets.
• Unpleasant smells coming from sinks, floor wastes or outside drains.
• Water backing up into showers, sinks or outdoor drains.
• Overflow Relief Gullies (ORGs) outside the home overflowing during use.

A blockage usually starts small and worsens over time. Having it inspected early can often prevent more extensive damage and costly repairs.

It depends on the severity of the blockage.

A blocked drain should be treated as an emergency if:

• Sewage is backing up inside your home.
  Toilets cannot be used.
• Wastewater is overflowing outside the property.
• Multiple fixtures throughout the home are blocked at the same time.
• The blockage is creating a health or safety risk.

If only one fixture is draining slowly, it may not be an emergency, but it should still be inspected before it becomes a complete blockage.

In the Sutherland Shire, the most common causes include:

• Tree roots entering cracked or ageing pipes.
• Wet wipes and sanitary products being flushed down toilets.
• Cooking fats, oils and grease building up inside kitchen drains.
• Hair and soap residue in bathroom wastes.
• Broken, collapsed or misaligned pipes.
• Leaf litter and stormwater debris after heavy rain.
• Older earthenware drains found in many established homes.

Many blocked drains are caused by more than one issue, which is why identifying the underlying cause is just as important as removing the blockage.

The best method depends on what is causing the blockage.

A professional blocked drain service typically includes:

• Locating the blockage.
  Clearing it using specialised equipment such as a high-pressure water jetter.
• Inspecting the entire drain with a CCTV drain camera.
• Identifying the cause of the blockage.
• Advising whether any repairs or preventative maintenance are recommended.

Simply making the water flow again isn’t enough. A proper inspection helps ensure the blockage doesn’t return because the real cause was missed.

Chemical drain cleaners are generally not recommended.

While they may temporarily clear very minor build-ups, they often:

• Don’t remove the actual blockage.
• Can damage certain types of pipework and seals.
• May create safety risks for anyone working on the drain later.
• Can make diagnosing the real problem more difficult.

If your drain continues to block after using a chemical cleaner, it’s usually a sign that professional investigation is required.

A few simple habits can greatly reduce the chance of future blockages:

• Never pour fats, oils or grease down the sink.
• Avoid flushing wet wipes, paper towels or hygiene products.
• Use strainers to catch hair and food scraps.
• Keep trees and large shrubs away from underground sewer pipes where practical.
• Arrange regular CCTV drain inspections if you’ve experienced previous blockages or tree root problems.
• Have older drains professionally maintained before they become completely blocked.

Preventative maintenance is almost always less expensive than dealing with an emergency blockage.

If the same drain blocks repeatedly, there is usually an underlying issue rather than just a simple blockage.

Common causes include

• Tree roots.
• Damaged pipes.
• A sag in the drain (where water pools), grease build-up.
• An incorrectly graded pipe.

A CCTV drain camera inspection can identify the cause so the correct long-term solution can be recommended.

Yes. Left untreated, blocked drains can lead to overflowing wastewater, water damage, unpleasant odours, mould growth and even damage to your home’s foundations or landscaping. Prompt attention can help minimise both repair costs and inconvenience.

Not necessarily. Tree roots can often be removed using specialised equipment such as a high-pressure water jetter. After the roots are cleared, a CCTV inspection allows the plumber to assess the condition of the pipe. Depending on the extent of the damage, the drain may only require ongoing maintenance, pipe relining or, in more severe cases, replacement.

Most straightforward blockages can be cleared within one to two hours. However, more complex problems involving tree roots, collapsed pipes or multiple blockages may require additional investigation and repairs. A CCTV inspection provides a clear picture of the condition of the drain and any further work that may be required.

It depends on your policy and the cause of the blockage. While most insurers won’t cover routine maintenance or wear and tear, some policies may cover damage resulting from a sudden pipe collapse or an insured event. It’s always worth checking with your insurer.

Yes. CCTV drain cameras allow our plumbers to inspect the inside of the pipe after clearing the blockage. This helps identify the exact cause, confirms the drain is flowing correctly and provides recommendations if repairs or ongoing maintenance are required.

Not always, but in most cases it’s highly recommended. A CCTV drain camera inspection allows us to confirm the blockage has been completely cleared, identify what caused it and check for cracked pipes, tree root intrusion or other hidden damage. Without inspecting the drain, there’s a higher risk of the blockage returning because the underlying problem hasn’t been identified. For many homeowners, the camera inspection provides valuable peace of mind and helps avoid unnecessary future callouts.
