What is the most effective way to prevent blocked drains in Melbourne?

The most effective prevention measures are: never pour fat or grease down kitchen drains, use hair catchers in shower drains and clean them after every use, never flush wipes or cotton products, and have your sewer drain CCTV inspected every 3-5 years if you have large trees within 10m of your sewer line.

Are chemical drain cleaners effective for blocked drains?

Chemical drain cleaners (caustic soda, sulphuric acid products) can clear minor grease blockages in kitchen drains but are ineffective against hair blockages, tree roots, or structural issues. They also damage older PVC and rubber fittings. A drain machine or hydro-jet is more effective and less harmful to your pipes.

How often should I get my drains professionally cleaned?

Most Melbourne homes don't need scheduled drain cleaning. If you have large trees near your sewer line, a 3-5 year hydro-jet clean can prevent root build-up. If you've had a blockage due to grease or debris, an annual clean may be worthwhile until habits change. Your plumber can advise based on your specific drain inspection results.

Drain Maintenance Tips for Melbourne Homeowners — Prevent Blockages Before They Happen

Most blocked drains aren’t random events — they’re the result of gradual build-up that could have been prevented with simple maintenance habits. Melbourne homeowners who maintain their drains spend significantly less on emergency plumbing over time.

Kitchen Drain Maintenance

The #1 rule: no fat or grease down the drain

Fat and grease are liquid when hot but solidify as they cool in your drain pipe. Over time, grease coating the inside of your drain pipe accumulates other debris — food scraps, soap, hair — until the pipe is blocked. This is the primary cause of kitchen drain blockages in Melbourne homes and restaurants.

Dispose of cooking fat in the bin (let it solidify in the pan first, wipe out with a paper towel). If you pour fat down the drain, chase it with boiling water and dish soap — not a guaranteed fix, but better than nothing.

Use a sink strainer to catch food scraps
Run boiling water down the kitchen drain weekly
Monthly: pour half a cup of bicarb soda followed by half a cup of white vinegar, wait 30 minutes, flush with hot water

Bathroom Drain Maintenance

Hair is the primary cause of bathroom drain blockages. It accumulates at the drain cover and in the P-trap below.

Use a hair catcher on every shower drain
Clean the hair catcher after every shower — takes 5 seconds and prevents 90% of bathroom blockages
Monthly: remove the drain cover and use a drain snake or bent wire to clear any hair build-up below the cover
Never flush wet wipes, cotton balls, or facial wipes — even “flushable” wipes don’t break down and will block your sewer

Outdoor and Stormwater Drain Maintenance

Clear leaf litter from drain grates before autumn and winter (Melbourne’s plane trees drop significant leaf debris)
Check downpipe connections at ground level — a blocked connection means stormwater backs up against the house
Garden beds adjacent to drains: keep soil levels below the drain grate to prevent soil ingress

What Not to Put Down Any Drain

Wet wipes (including “flushable”)
Cotton buds or cotton wool
Cooking fat, oil, or grease
Coffee grounds
Feminine hygiene products
Paper towel or tissues
Paint or chemical solvents

When Maintenance Isn’t Enough

If you have recurring blockages despite good drain habits, the problem is structural: tree roots, a collapsed joint, offset pipe, or build-up that requires hydro-jet cleaning to remove completely. No amount of bicarb soda will fix a root intrusion.
