What Causes Smelly Drains in Sydney?
Drain odours are never normal. Here are the most common causes our plumbers find across Sydney homes.
How We Fix It
We don’t just mask the smell — we find and fix the source permanently.
How We Fix Smelly Drains
From your call to a fresh-smelling home — here’s how we get it done.
Tell us about the smell — which drains, how long, how bad. We’ll book a same-day visit. Available 24/7 including weekends. $0 call out fee*.
Our plumber runs a HD CCTV camera through your drains to find the exact cause — blocked pipe, dry trap, tree roots, cracked sewer vent, or bacteria buildup. No guesswork.
We show you the CCTV footage, explain the problem, and give you an upfront fixed price. Most smelly drain jobs are completed within 1–2 hours. Lifetime guarantee on workmanship.
Why DIY Drain Cleaners Won’t Fix Smelly Drains
Pouring bleach or baking soda down a smelly drain might mask the odour for a few hours — but it never fixes the real problem. Supermarket drain cleaners can actually corrode your pipes, making things worse.
- Chemical cleaners damage pipes — they eat away at older clay and PVC
- The smell always comes back — because the cause is still there
- Sewer gas is a health hazard — hydrogen sulphide can cause headaches and nausea
- A CCTV camera finds the real cause — so we fix it permanently, the first time
Don’t Ignore Smelly Drains — It Gets Worse
A smelly drain is your plumbing system telling you something is wrong. Left untreated, the problem escalates — from a bad smell to sewage backup, water damage, or a health hazard.
- Sewage backup — blocked sewers can overflow into your home
- Structural damage — leaking pipes erode foundations and flooring
- Health risks — mould, bacteria, and sewer gas exposure
- Higher repair costs — small fixes become major pipe replacements

FAQS
Answer:
Smelly drains in Sydney are usually caused by blocked pipes, dry P-traps (common in unused bathrooms), cracked sewer vents, tree root intrusions, or bacteria buildup in the drain line. Sydney’s clay soil and older pipe systems make root intrusion particularly common. A CCTV drain camera inspection finds the exact cause.
Answer:
Drain clearing starts from $49* with Mr Splash Plumbing. The total cost depends on the cause — a simple P-trap fix or jet blast may be under $200, while a cracked sewer line or tree root removal typically ranges from $200–$600. We always provide an upfront fixed price before starting work. $0 call out fee*.
Answer:
Pouring boiling water or baking soda down the drain may temporarily reduce odour, but it won’t fix the underlying cause. Supermarket drain cleaners can actually corrode your pipes. A licensed plumber uses a CCTV drain camera to find the real problem and fix it permanently.
Answer:
We offer same-day service for smelly drain repairs across Sydney. Most jobs are completed within 1–2 hours. For emergencies, we’re available 24/7 — call 1300 677 752.
Answer:
A rotten egg smell from your shower drain is usually hydrogen sulphide gas produced by bacteria in the drain line, or sewer gas coming through a dry or broken P-trap. If you haven’t used the shower in a while, try running water for 30 seconds to refill the trap. If the smell persists, you need a professional diagnosis.
Answer:
Kitchen sink smells are most commonly caused by grease, food scraps and biofilm buildup inside the drain pipe. Over time these decompose and produce foul odours. High-pressure jet blasting clears the buildup completely. We also check for blocked or damaged vents that can trap odour.
Answer:
Yes, it can be. Sewer gas contains hydrogen sulphide and methane — exposure can cause headaches, nausea, dizziness, and in severe cases is flammable. If you smell sewage inside your home, you should call a licensed plumber promptly.
Answer:
Yes. We offer a lifetime guarantee on workmanship for all drain repairs. If the smell comes back due to our work, we’ll fix it at no charge. We’re licensed (#306457C) and fully insured.
