Got a dodgy smell coming from your drains? Yeah, right – it’s pretty grim, and we know it. Smelly drains are super common in Melbourne homes, and the good news is they’re usually fixable. Heritage Plumbing Group has been sorting out these pongy problems for over 40 years, so we reckon we know a thing or two about getting rid of those nasty whiffs.

Look, that smell wafting up from your kitchen or bathroom sink isn’t just annoying – it’s actually telling you something’s up with your plumbing. Smelly drains happen when stuff like food scraps, grease, hair, and general gunk builds up in your pipes. All that muck sits there decomposing, and the bacteria having a party in there release some pretty foul gases that travel back up through your drains.
You know that curved pipe under your sink? That’s called a P-trap, and it’s meant to hold water that blocks sewer gases from sneaking into your home. When that trap dries out or gets dodgy, those gases just waltz right through. Sometimes it’s a blocked vent pipe on your roof stopping air from moving through your drainage system properly. Whatever’s causing it, those pongs aren’t going anywhere on their own, and putting it off usually means bigger headaches later on.
Sure, the odd minor whiff might be fine to tackle with a quick clean, but some signs mean it’s time to get a pro in. If you’re copping a constant rotten egg smell, that’s hydrogen sulphide gas – basically a big flashing sign that organic stuff is breaking down deep in your pipes. Anything that smells like sewage is even worse and needs sorting straight away.
See if the smell gets worse when you turn on the taps or use certain drains. If a bunch of drains around your place are all smelling funky at once, you might have a main sewer line drama rather than just one blocked pipe. And if your drains are running slow on top of the bad smells? That’s a definite red flag – you’ve probably got a decent blockage that’s only getting nastier. Don’t wait until you’ve got water backing up everywhere. Getting professional smelly drains repair means finding out what’s actually wrong and fixing it properly.
Here’s the thing – blockages and smelly drains are basically best mates. When water can’t flow through your pipes like it should, all the gunk builds up and creates stagnant puddles where bacteria absolutely thrive. In the kitchen, cooking oils and food bits coat your pipes and trap even more stuff over time. That greasy buildup turns into a sticky, stinky nightmare that just keeps getting worse.
Bathroom drains have their own battles – hair, soap scum, and all those shampoos and body washes combine to form stubborn clogs that absolutely reek as they break down. Even your laundry and outdoor drains cop it. Lint, dirt, and leaves can create blockages that smell musty and earthy. These blockages aren’t just gross; they also slow your drainage down, put pressure on your pipes, and can end up causing leaks or even bursts. Tree roots getting into underground pipes are a pretty common issue around Melbourne too, creating blockages that trap waste and generate absolutely awful smells. Getting a professional to clear these blockages is the only real way to kill the odours and look after your plumbing.
Here’s the good bit – you can actually prevent a lot of drainage smells with some regular TLC. Start by running hot water through your drains each week to help wash away any minor buildup. For kitchen sinks, don’t pour cooking oils or grease down there; chuck them in the bin instead. Use sink strainers to catch food bits and hair before they go down your pipes.
Once a month, tip some baking soda down your drains followed by white vinegar, let it do its fizzy thing for about 15 minutes, then flush it all through with hot water. This natural trick helps break down organic gunk without harsh chemicals that can wreck older pipes. Make sure your P-traps stay filled with water – if you’ve got a spare bathroom or laundry that doesn’t get used much, run water through those drains every month or so to keep that water seal working.
Get your drains checked professionally once a year, especially if you’re in an older Melbourne home. We can use camera tech to spot potential dramas before they turn into smelly disasters, which saves you cash and hassle down the track.

Frequently Asked Questions
Smelly drains are usually down to a build-up of organic gunk in your pipes – stuff like food scraps, grease, hair, and soap scum. As all that stuff breaks down, bacteria produce some pretty nasty smells. Dry P-traps, blocked vent pipes, or tree roots in the sewer line can also let those odours drift back into your home.
For a quick fix, tip some baking soda down the drain, follow it with white vinegar, let it fizz for about 15 minutes, then flush it through with hot water. Running hot water regularly can help as well. If the smell keeps coming back though, there’s likely a deeper blockage going on, and you’ll need a plumber to take a proper look.
Bathroom drains can suddenly smell bad when hair, soap scum, and personal care products build up and create a clog. Sometimes the P-trap dries out if the drain hasn’t been used in a while, letting sewer gases through. It could also mean there’s a blockage further down your pipes that needs clearing out.
Give us a bell if the smell won’t budge after you’ve had a crack at cleaning, if it reeks like rotten eggs or sewage, if heaps of drains are whiffy at the same time, or if your drains are draining slow as. These are dead giveaways there’s a proper blockage or plumbing drama that needs a pro.
