Blocked drains are one of the most common — and most avoidable — plumbing problems in Melbourne homes. A blocked drain left untreated can quickly turn into a backed-up toilet, a flooded laundry, or a cracked pipe that costs thousands to repair.
The good news? Most blocked drains are caused by the same handful of things — and with a few simple habits, you can prevent the majority of them entirely. As a Craigieburn-based plumber working across northern Melbourne every day, here are the 10 tips I give to every homeowner.
Tip 1: Put a Drain Strainer in Every Sink and Shower
Hair, soap scum, and food scraps are the number one cause of blocked drains inside the home. A simple mesh drain strainer catches debris before it enters your pipes. They cost a few dollars at any hardware store and take seconds to empty. It's the single easiest thing you can do to prevent blockages.
Tip 2: Never Pour Grease or Oil Down the Drain
Fat, oil, and grease solidify inside your pipes as they cool, building up over time until flow is restricted or stopped completely. Always let cooking oil cool and pour it into a container, then throw it in the bin. Wipe greasy pans with paper towel before washing. This one habit can add years to the life of your kitchen drain.
Tip 3: Be Careful What You Flush
Toilets are designed to handle human waste and toilet paper — nothing else. Wet wipes (even those labelled 'flushable'), cotton pads, nappies, and paper towels do not break down in the pipe system and are a leading cause of serious sewer blockages. Keep a bin in the bathroom and use it.
Tip 4: Run Hot Water Down the Sink After Every Use
After washing up or using the kitchen sink, run hot water for 30 seconds. This helps flush any small grease deposits or food particles through the pipe before they have a chance to accumulate. A small habit that makes a real difference over time.
Tip 5: Know Where Your Trees Are
Tree roots are the number one cause of underground drain damage in northern Melbourne's newer and established suburbs alike. Roots naturally grow toward moisture and will infiltrate any small crack or joint in your drainage pipes. If you have large trees — especially gums, willows, or figs — close to your drain lines, have them inspected every 2–3 years.
If your drains are backing up repeatedly and you have large trees nearby, tree root infiltration is the most likely cause. A CCTV drain inspection will confirm the location and extent of root intrusion before any repair work begins — saving you money on guesswork. Learn more on our Services page.
Tip 6: Clean Your Drain Stoppers Regularly
Bathroom basin and bath drain stoppers collect hair and soap residue underneath them, even if the surface looks clean. Pull them out monthly, clean off any buildup, and rinse with hot water. It takes two minutes and prevents slow-draining sinks from becoming fully blocked ones.
Tip 7: Use Baking Soda and Vinegar — Not Chemical Drain Cleaners
Liquid chemical drain cleaners are corrosive and can damage pipe joints and seals over time, particularly in older homes. For minor slow drains, a monthly flush of baking soda followed by white vinegar and then hot water is a far gentler and surprisingly effective alternative. It won't fix a serious blockage, but it keeps pipes flowing freely.
Tip 8: Don't Plant Water-Loving Trees Near Drainage Lines
If you're landscaping a new home in Craigieburn, Mickleham, or Kalkallo, be strategic about where you plant trees. Willows, poplars, bamboo, and some native gums have aggressive root systems that seek out underground water sources — including your drain pipes. Ask your plumber where your drainage lines run before you plant anything large near the boundary or back fence.
Tip 9: Schedule a Preventive Drain Inspection Every Few Years
You don't need to wait for something to go wrong before checking your drains. A CCTV drain inspection every 2–3 years — or when you move into a new property — gives you a clear picture of your pipe condition and catches small issues before they become expensive ones. This is especially important in homes over 15 years old or properties with large established trees. Consider a SmartCare Maintenance Plan to stay ahead of it.
Tip 10: Act Early When You Notice Warning Signs
The single biggest mistake homeowners make is ignoring early warning signs and hoping the problem resolves itself. It rarely does. If you notice slow draining, gurgling sounds, foul smells near drains, or water backing up in unusual places — call a plumber early. A minor blockage cleared promptly costs a fraction of what a burst or collapsed pipe costs to repair.
Warning Signs Your Drains Are Heading for a Blockage
Keep an eye out for these early indicators — catching them early saves money and stress:
If more than one drain is backing up simultaneously, this is a strong sign of a blockage in your main sewer line — not just a single pipe. This needs urgent attention. Call Momentum Plumbing on 0400 362 044 for same-day service across Craigieburn and northern Melbourne.
When Prevention Isn't Enough — Call a Local Plumber
Even with the best habits, blockages sometimes happen — particularly in older homes, properties with large trees, or newly built estates where construction debris has been left in drainage lines. When they do, it's important to call a licensed plumber rather than reaching for a chemical drain cleaner or a hire-shop drain snake.
