FAQs | BLOCKED DRAINS & SLOW DRAINS
How Do I Unblock a Kitchen Sink?
What might you be experiencing?
The sink may drain slowly, stop draining completely or make gurgling noises. Water might also return through the second sink bowl or produce an unpleasant smell.
What is likely causing the problem?
Common causes include:
- Grease, oil and food scraps
- Soap and detergent buildup
- A blocked sink trap
- Debris lodged inside the waste pipe
- A blockage further along the household drain
- Damaged or incorrectly installed pipework
What can you do to fix it?
Remove visible debris from the waste opening and use a sink plunger to loosen minor blockages. If accessible, the removable sink trap can be cleaned after the water has been contained. Avoid chemical drain cleaners, as they can be hazardous and may damage some pipework.
If the blockage returns, affects other fixtures or cannot be cleared safely, MAS Plumbing Solutions can clean the waste pipe and inspect the drainage system for further problems.
Why Is Water Coming Back Up Through the Floor Waste?
What might you be experiencing?
Water or wastewater may rise through a bathroom, laundry or kitchen floor waste when another fixture is used. You may also notice slow drainage, gurgling sounds, unpleasant smells or an overflow across the floor.
What is likely causing the problem?
Common causes include:
- A blockage further along the drainage pipe
- Grease, hair, soap or other debris
- Tree roots inside underground sewer pipes
- Cracked, collapsed or displaced drainage
- An incorrectly installed or restricted drain
- A blocked main sewer line
What can you do to fix it?
Stop using nearby sinks, showers, toilets and appliances to prevent further overflow. Avoid chemical drain cleaners and keep people away from wastewater because it may contain harmful contaminants.
MAS Plumbing Solutions can clear the blockage, inspect the drain with a CCTV camera and identify any damaged pipework causing the floor waste to overflow.
Why Does My Drain Smell?
What might you be experiencing?
You may notice musty, rotten or sewage-like odours coming from a sink, shower, bath or floor waste. The smell may be constant or become stronger after using nearby fixtures.
What is likely causing the problem?
Common causes include:
- Hair, soap, grease or food buildup
- A dry or faulty water trap
- A partial drain blockage
- A blocked or damaged drainage vent
- Leaking or incorrectly connected pipework
- A problem within the sewer drainage system
What can you do to fix it?
Remove visible debris, clean the waste opening and run water into drains that are rarely used to refill their traps. Avoid using harsh chemical drain cleaners or simply covering the smell without finding its source.
If the odour persists or is accompanied by gurgling, slow drainage or wastewater backups, MAS Plumbing Solutions can inspect and clean the drainage system and repair the underlying fault.
Why Are My Drains Making Gurgling Noises?
What might you be experiencing?
You may hear bubbling or gurgling sounds from a sink, shower, floor waste or toilet when water drains or another fixture is used. You might also notice slow drainage, unpleasant smells or changing water levels.
What is likely causing the problem?
Common causes include:
- A partial drain blockage
- Trapped air within the drainage system
- A blocked or faulty drainage vent
- Grease, hair, soap or debris buildup
- Tree roots inside underground pipes
- Damaged or incorrectly installed drainage
What can you do to fix it?
Remove visible debris and check whether several fixtures are affected. Avoid repeatedly flushing toilets or running large amounts of water if drains are slow or backing up.
If the noise continues, MAS Plumbing Solutions can clear the blockage, inspect the drainage and identify any ventilation or damaged-pipe issues.
Is It Safe to Use Chemical Drain Cleaner?
What might you be experiencing?
You may have a slow or blocked sink, shower, bath or floor waste and be considering a chemical cleaner as a quick solution. These products may sometimes move minor buildup, but they often fail to clear the full blockage.
What are the potential risks?
Chemical drain cleaners can:
- Cause burns and release harmful fumes
- Damage some pipes, seals and fixtures
- React dangerously with other cleaning products
- Remain trapped inside a completely blocked drain
- Make the drain hazardous for anyone repairing it
- Temporarily open a drain without fixing the underlying cause
What should you do instead?
Remove visible debris and use a suitable plunger for a minor blockage. Never mix drain cleaner with bleach, acids or another chemical, and avoid using it in toilets unless the product specifically allows it.
For persistent or recurring blockages, contact MAS Plumbing Solutions.
How Do I Know if Tree Roots Are Blocking My Sewer?
What might you be experiencing?
Common warning signs include:
- Drains that repeatedly block or drain slowly
- Toilets that gurgle or change water level
- Several fixtures backing up at once
- Sewage smells inside or outside
- Wastewater overflowing from an outdoor drain
- Blockages returning after previously being cleared
What is likely causing the problem?
Tree roots can enter sewer pipes through cracks, displaced joints or deteriorated seals. This is particularly common in older earthenware or clay drainage. Once inside, the roots grow and collect waste, eventually restricting or completely blocking the pipe.
What can you do to fix it?
Tree-root intrusion cannot be confirmed from symptoms alone. The drain should be cleared using suitable equipment and inspected with a CCTV drain camera to locate the roots and assess the pipe’s condition.
MAS Plumbing Solutions can remove tree roots, complete a CCTV inspection and recommend pipe repairs, replacement or drain relining where appropriate.
Why Does My Sewer Overflow After Heavy Rain?
What might you be experiencing?
Wastewater may overflow from an outdoor drain, toilet or floor waste during or shortly after heavy rain. You might also notice slow drainage, gurgling fixtures, sewage smells or water backing up inside the property.
What is likely causing the problem?
Common causes include:
- A partially blocked sewer pipe
- Tree roots restricting the drainage
- Cracked or displaced sewer pipes allowing groundwater to enter
- Stormwater incorrectly connected to the sewer
- A damaged boundary trap or inspection opening
- An overloaded local sewer network
What can you do to fix it?
Minimise water use, avoid contact with wastewater and keep children and pets away from the affected area. Do not open drain covers or use chemical drain cleaners.
MAS Plumbing Solutions can clear and inspect the sewer with professional equipment, identify damaged pipework or incorrect connections and recommend appropriate repairs.
