Slow Draining Water and Backups

Slow draining from sink shower, tub, or toilet can test your patience, signalling the early signs of a blocked drain. In some cases, drains may back up entirely - with sinks overflowing, shower water pooling around your feet, or toilets refusing to flush properly.

When you’ve got slow drainage issues, homeowners can often identify a sign blocked drain by noticing a gurgling sound as water struggles to pass through the obstructed drain pipes.

A single clog or obstruction narrowing the drain pathway is typically to blame for slow draining and backups.

A build-up from the bath, shower, and other debris of hair, grease, can also signify a blocked pathway in our drain pipes over time.

Should sinks, tubs, or toilets in your Dulwich Hill home drain more slowly than usual, take action. Contact Dulwich Hill Plumbing on 1300 349 338 for swift help with blockages, without a call out fee.

Gurgling Noises Coming from Pipes

Gurgling noises directly from your sink or shower drain are a sign to take note of and may necessitate an effort to clear blockage. These bubbling, rumbling, gurgling sounds tend to signal that there is trapped air in your drainage system due to a partial or full blockage.

When you hear gurgling, it’s a significant cue that theres blockage ready to go down, with many homeowners recognising this as a telltale sound of a clogged drain line or vent stack. When water battles to navigate past narrow, debris-clogged pipes, it’s a sign there blockage in your drains may exist, with your walls even responding with distinctive air pockets disrupting the flow. This causes bubbles and rumbling sounds more than familiar as ‘gurgling’.

The location of the blockage often determines whether gurgling noises are joined by slow drainage, foul odours, or visible water backups.

Your plumber knows that early intervention when you suspect a blockage in your home is key. Our expert team will identify blocked issues and have your pipes flowing freely again in no time.

Foul Sewer Odors

Be alert to one stark indicator of a blockage: foul, rotten smells emanating from your sinks or floor drains. Bad smells coming from your drains can be attributed to the buildup of organic waste, sewage material, grease, and food scraps decomposing within a blocked pipe.

Blockages that constrict your sewer drain opening can trap gases from decomposing solids and waste, creating a 'bottle neck’ effect. What may start as a small blockage in your sewer can rapidly evolve into a more serious mass of stagnant sewage buildup if left unchecked, releasing increasing odours into your home.

Homeowners may initially detect a 'rotten eggs’ smell after using the kitchen sink or shower.

It’s best to call plumber from Dulwich Hill’s expert team on 1300 349 338 if signs like rancid smells indicate there’s a blockage around sinks, drains or toilets.

Increased Toilet Water Levels

One sign of a blocked drain that should never be overlooked is when there’s a noticeable rise in your toilet’s water level. If you notice water sitting significantly higher than normal, barely draining between flushes, it likely indicates debris & buildup is obstructing the sewer connection.

You need make sure the under-property drainage pipes, including the sewer drain, aren’t clogged to prevent wastewater from being trapped and unable to drain away from the toilet bowl. Causing water levels to creep up over time. This backup, which is a clear indication of drain blockage, also prevents water from draining away smoothly, causing gurgling sounds as air pockets form in the obstructed pipes.

A variety of materials such as tree roots, grease, and dirt can amass to block the main drain, leading to a blocked sewer line connected to the toilet. Don’t hesitate to call Dulwich Hill Plumbing on 1300 349 338 if you notice this warning sign.

I called the experts when problems were left unaddressed, recognising that increased water levels can lead to foul odours, flooding, sewer backups, or pipe damage. We’ll diagnose the issue and clear any stubborn clogs.

Multiple Clogged Fixtures

One of the clearest signs your sewer may be blocked is when multiple plumbing fixtures start draining slowly or getting backed up simultaneously, often accompanied by a foul smell. This simultaneous clogging suggests the blockage is located further down the main sewer line, rather than small buildups in individual branch drain lines.

Major sewer clogs, which can result in bad smells coming from your drain, might be due to invasive tree roots, a collapsed/damaged drainage pipe, or substantial build up of waste, grease and debris. Call Dulwich Hill Plumbing immediately on 1300 349 338 if all fixtures exhibit blocked drain symptoms - we’ll send our drainage specialists out to diagnose the issue.

Left unchecked, these signs can indicate extensive backups leading to sewage flooding in your home.

Preventing Future Blockages

Prevent blocked drains by staying vigilant with smart habits, such as turning off water when not in use, routinely cleaning washing machine filters, and performing regular maintenance.

Here are top tips, including baking soda, to prevent blockages and maintain clear, free-flowing drains:

  • Mind your grease - Cool and solidify oils before discarding them in the bin, not the sink, to prevent grease-related clogs.
  • Use drain strainers - Fit mesh screens over sinks & tub drains to catch hair/debris before it enters pipes.
  • Flush only the 3 P’s - Toilets should only tackle human waste and toilet paper to avoid snags in the pipes.
  • Clean with care - Harsh chemical cleaners can damage pipes and disrupt helpful bacteria/enzymes.
  • Try one more monthly enzyme treatment - Pour a microbial drain cleaner down sinks & tub drains to digest buildups.

Even with diligent care, unexpected issues such as signs of blocked drains can emerge. Dulwich Hill Plumbing offers a $99 drain camera inspection to diagnose signs your drains may be in trouble before issues worsen. Stay vigilant to save future plumbing headaches - call us anytime on 1300 349 338!

Our Blocked Drain Services

At Dulwich Hill Plumbing, we provide a full spectrum of services to diagnose and repair drain issues, ensuring your pipes are functioning perfectly.

Our team of licensed drainage experts provides prompt and efficient service, effectively identifying and resolving clogs and obstructions. We possess sophisticated equipment that accurately identifies issues and employ advanced techniques to clear even persistent blockages.

Blocked Drain Inspections & Diagnostics

If you suspect a hidden clog or sewer issue churning out your peace of mind, we provide thorough blocked drain inspections using our digital drainage camera. Our plumber inserts a small flexible camera down into your pipes to pinpoint blockages, inspect integrity for cracks/damage, and assess if tree roots have invaded the line.

A precise diagnosis from our detailed inspection enables our adept team to tailor solutions specific to the type and location of the blockage. It also helps identify major problems early before they cause pipe failure or sewer flooding.

High-Pressure Water Jet Drain Cleaning

Once the blocked drain inspection has identified the obstruction, we use specialised jet drain machines to blast away any material clogging pipes. High-powered water jets exert up to 5000 PSI to scour your drains, ensuring the drain can cut through tough grease, waste buildup and even tree roots that often invade pipes.

The hydrojetting technique effectively cleans pipes for smooth, unimpeded water flow. Safe for all pipe materials too.

For preventative maintenance, we conduct chemical drain cleaning with professional-grade solutions.

CCTV Drain Inspections

For extensive, recurring clogs or suspected system-wide problems, we advocate a CCTV drain inspection. Our plumber feeds a special 360-degree rotating CCTV camera down your drain line to thoroughly assess pipes.

This creates a detailed video documentation of your underground drainage system to identify any damaged pipes, intruding tree roots, misaligned joints, or other faults allowing debris and roots to enter, leaving you very happy with the clarity of the situation. With precise diagnostics, we can find and strategically repair any vulnerabilities to prevent future headaches.

Act before sewage backups or foul smells worsen. For immediate help with any blockage, call Dulwich Hill Plumbing on 1300 349 338—our prompt 24/7 response ensures smooth plumbing operations.
