Sewer, Drains & Blockages

Sewer, Drain & Blockage Services

Professional sewer and drain services for blocked toilets, sinks, showers, stormwater lines, damaged pipes and recurring drainage problems.

The Plumb King provides practical drain and sewer solutions for homes, rental properties, strata buildings and commercial premises. Whether you have a slow drain, a blocked toilet, wastewater backing up or a recurring sewer problem, we can assess the symptoms, identify the likely cause and recommend the most suitable next step.

Complete Sewer, Drain & Blockage Services

Drainage systems carry wastewater away from toilets, basins, sinks, showers, baths, laundries and commercial fixtures. When a pipe becomes blocked, damaged or poorly graded, water may drain slowly, overflow, produce unpleasant odours or back up into the property.

Not every blockage has the same cause. Some are local and caused by hair, grease, soap residue or foreign objects. Others are linked to tree roots, cracked pipes, collapsed sections, poor fall, ground movement or ageing sewer infrastructure. A proper assessment helps avoid repeated short-term fixes where a larger problem is present.

Blocked Drains

A blocked drain may begin as slow water flow, gurgling or unpleasant odours before becoming a complete blockage. The affected fixture, the age of the plumbing and whether several drains are involved can help indicate where the problem is located.

Local blockages are often limited to one fixture. When several fixtures are affected, the issue may be further along the drainage system or within the main sewer line.

Blocked Toilets

A blocked toilet may be caused by excessive paper, wipes, sanitary products, foreign objects or a blockage within the downstream drain. Repeated toilet blockages can also indicate a damaged or restricted sewer line.

Avoid repeatedly flushing a toilet that is already full, as this can cause wastewater to overflow onto the floor. Stop using the fixture and arrange an assessment.

Blocked Sinks and Basins

Kitchen sinks commonly block due to grease, food particles and detergent residue. Bathroom basins may become restricted by hair, soap and personal-care products.

Slow drainage may be improved by clearing the local waste, but recurring problems can indicate a restriction deeper within the system.

Blocked Showers and Baths

Hair, soap residue and debris can collect in shower and bath wastes. Warning signs include slow drainage, water pooling around the waste and gurgling sounds.

Where several bathroom fixtures are draining poorly, the issue may involve a shared branch drain rather than the individual shower or bath.

Blocked Laundry Drains

Laundry drains can become restricted by lint, detergent residue, fibres and debris. Washing machine wastewater can quickly overwhelm a partially blocked waste and cause overflow.

Blocked Floor Wastes

Floor wastes are designed to collect water from bathrooms, laundries, commercial kitchens and other wet areas. They can block with sediment, debris, grease or material washed across the floor.

Blocked Stormwater Drains

Stormwater drains commonly block with leaves, soil, roots, silt and debris. A blocked stormwater system may cause pits to overflow, gutters to back up or water to pool around the property during rain.

Because stormwater and sewer systems serve different purposes, the correct line should be identified before cleaning or repair work begins.

Sewer Blockages

Sewer blockages can affect toilets, showers, sinks, floor wastes and external overflow points. Signs may include wastewater backing up, several fixtures draining slowly, sewage odours or gurgling through the plumbing system.

Common sewer blockage causes include:

• Tree root intrusion
• Wipes and sanitary products
• Grease and fats
• Collapsed pipe sections
• Cracked or displaced joints
• Poor pipe fall
• Ground movement
• Foreign objects
• Ageing pipework

Drain Cleaning

Drain cleaning removes restrictions and accumulated material from the pipe. The method used depends on the drain size, blockage type, access and pipe condition.

Clearing the blockage restores flow, but if the issue returns, further investigation may be needed to identify damage or another underlying cause.

High-Pressure Water Jetting

High-pressure water jetting can remove grease, roots, sediment and built-up material from many drainage lines. The equipment uses controlled water pressure to clean the internal pipe surface and move debris through the system.

The suitability of jetting depends on pipe condition and access. Fragile or badly damaged pipes may require a different approach.

CCTV Drain Inspections

A CCTV drain inspection uses a camera to view the inside of accessible sewer or drainage pipes. It can help identify tree roots, cracks, displaced joints, collapsed sections, scale, foreign objects and other defects.

CCTV footage is especially useful when blockages recur or where repair options need to be considered.

Tree Roots in Drains

Tree roots can enter drains through cracked pipes, damaged joints or small openings. Once inside, they may grow rapidly and trap paper, grease and debris, leading to repeated blockages.

Root cutting or jetting can restore flow, but the underlying pipe defect may still need repair, relining or replacement.

Drain Repairs

Drain repairs may be required where a pipe is cracked, displaced, collapsed or leaking. The repair method depends on the location, depth, access, pipe material and extent of the damage.

Possible repair options can include:

• Localised excavation and replacement
• Replacing damaged pipe sections
• Repairing joints and connections
• Installing new inspection points
• Correcting poor fall where practical
• Pipe relining where suitable
• Partial or full drain replacement

Pipe Relining

Pipe relining can sometimes repair damaged drains from inside the existing pipe without full excavation. A liner is installed to create a new internal pipe surface through the damaged section.

Relining is not suitable for every drain. The pipe condition, shape, access and extent of collapse need to be assessed before it can be recommended.

Drain Replacement

Replacement may be required where the pipe is badly collapsed, extensively damaged, poorly graded or unsuitable for relining. New pipework can also provide better access and future maintenance points.

Repair, Relining or Replacement?

Clearing May Be Enough When:

• The blockage is localised
• The pipe is structurally sound
• The problem has not been recurring
• There is no evidence of major damage

Repair or Relining May Be Better When:

• Roots keep entering the same section
• There is a localised crack or damaged joint
• Excavation access is difficult
• The pipe shape and condition are suitable

Replacement May Be Better When:

• The pipe has collapsed
• There are widespread defects
• The fall is inadequate
• The pipe is undersized or badly deteriorated
• Repeated clearing does not provide a lasting result

Common Signs of a Drainage Problem

• Slow-draining sinks, showers or baths
• Toilets that rise before draining
• Gurgling sounds
• Sewage or drain odours
• Water backing up through floor wastes
• Several fixtures affected at once
• Overflowing external drains
• Recurring blockages
• Wet or sunken ground over buried pipes
• Stormwater pits overflowing during rain

What Not to Put Down Drains

• Cooking oil and grease
• Wet wipes
• Sanitary products
• Paper towel
• Nappies
• Food scraps
• Paint and chemicals
• Coffee grounds
• Building debris
• Garden soil and leaves

Preventative Drain Maintenance

• Keep grease and food scraps out of kitchen drains
• Use suitable strainers in sinks and showers
• Do not flush wipes or sanitary products
• Keep stormwater pits and grates clear
• Investigate recurring slow drainage
• Maintain accessible inspection points
• Address tree root intrusion early
• Avoid planting large trees over known sewer lines
• Repair damaged pipes before defects worsen
• Keep records of recurring blockage locations

Residential Drainage Services

We assist homeowners with blocked toilets, sinks, showers, floor wastes, sewer lines and stormwater drains. Early assessment can help limit damage and reduce inconvenience.

Rental Property Drainage

Drainage faults can quickly disrupt tenants and damage the property. When booking, provide access details, tenant information, approval limits and any previous blockage history.

Strata Drainage

Strata drainage can involve private lots, common property and shared sewer lines. Responsibility may depend on the location and cause of the blockage or damage.

Commercial Drainage Services

Commercial drainage systems may serve offices, hospitality venues, retail premises, warehouses and managed buildings. Higher usage can make planned maintenance and prompt blockage response especially important.

Frequently Asked Questions

What causes blocked drains?

Common causes include grease, hair, wipes, roots, foreign objects, damaged pipes and poor fall.

Why do my drains keep blocking?

Recurring blockages can indicate tree roots, cracks, displaced joints, collapse or another structural problem.

Can you clear a blocked toilet?

Yes. The blockage may be within the toilet, branch drain or main sewer line.

What is high-pressure water jetting?

It uses controlled water pressure to remove grease, roots, sediment and debris from drainage pipes.

What is a CCTV drain inspection?

It uses a camera to inspect the internal condition of accessible drains and identify defects.

Can tree roots damage sewer pipes?

Yes. Roots can enter damaged joints, grow inside the pipe and contribute to cracking or collapse.

Can blocked stormwater drains be cleared?

Yes. The line may need cleaning, inspection or repair depending on the cause.

Can pipes be repaired without excavation?

Sometimes. Pipe relining may be suitable where the pipe condition and access allow.

When does a drain need replacing?

Replacement may be needed where the pipe is collapsed, badly damaged, poorly graded or unsuitable for relining.

Why does my toilet gurgle?

Gurgling can indicate restricted airflow or a blockage within the drainage system.

Why does water come up through the floor waste?

This can happen when a downstream drain is blocked and wastewater backs up through the lowest outlet.

Can grease block kitchen drains?

Yes. Grease can cool and build up inside pipes, trapping food and debris.

Should wet wipes be flushed?

No. Even products labelled flushable can contribute to blockages.

Can you inspect drains before buying a property?

A CCTV inspection may help identify accessible drainage defects, subject to access and scope.

Can several blocked drains be connected?

Yes. When multiple fixtures are affected, the blockage may be in a shared branch or main line.

How can I prevent blocked drains?

Avoid putting grease, wipes, food scraps and foreign objects into drains, and investigate recurring slow drainage early.

Do you provide commercial drain services?

Yes. We can assess blocked drains, recurring issues and damaged drainage systems in commercial properties.

Can blocked drains cause property damage?

Yes. Wastewater or stormwater overflow can damage floors, walls, cabinetry and landscaping.

What information helps with a drain quote?

Provide the affected fixtures, blockage history, photos, access details and any previous CCTV or repair information.

Can you assess several drainage problems at once?

Yes. Providing the complete list can help determine whether the issues are connected.
