Who's Responsible for Blocked Drains?

Here's the Aussie Breakdown

Before you ring a plumber, it’s important to know where the issue lies — and who’s actually responsible for clearing those blocked drains. Read on to find out.

Blocked drains — they’re a real hassle. Whether you’re a homeowner or renting a place, when the water starts backing up or the smell hits, the first thing you ask is: “Do I have to fix this?”

Let’s clear the air, mate. In this guide, we break down who’s actually responsible for sorting out blocked drains in Aussie households — tenants, landlords, or the local council.

The Basics: What Causes Blocked Drains?

Blocked drains can strike anyone, anywhere — from tree roots invading pipes to built-up grease, food scraps, or even kids’ toys flushed down the loo (don’t ask).

When it happens, the key is figuring out where the blockage is.

Step 1: Is It a Private or Public Drain?

🔹 Private Drains
If the blockage is on your property — say, under your backyard or inside your home — it’s generally your responsibility to sort it.

🔹 Public Drains
If the issue lies beyond your property line — like under the footpath or road — then it’s likely the local council or water authority’s problem.

Step 2: How to Locate the Issue

You don’t need to dig up your whole yard to find the problem. Plumbers use CCTV drain cameras to pinpoint where the blockage is.

Knowing the exact location helps you figure out whether it’s your job or someone else’s. Plus, it speeds up getting it sorted.

Tenants vs. Landlords: Who Cops the Bill?

If you’re renting:

  • The landlord is usually responsible for maintenance like blocked drains — especially if it’s due to ageing pipes or tree roots.
  • If the blockage is caused by misuse (e.g. flushing wipes or pouring oil down the sink), the tenant may be liable.

Pro Tip: Check your lease agreement and contact your property manager straight away. Document everything.

Common Scenarios

1. Blocked kitchen sink from grease build-up?

  • Likely tenant responsibility (preventable misuse).

    • 2. Tree roots in the backyard sewer line?

  • Landlord’s responsibility (age-related maintenance).

    • 3. Overflowing stormwater drain near the road?

  • Likely a council issue (public infrastructure).

    • Homeowners: It’s On You (Mostly)

    If you own the property, then you’re on the hook for blockages within your boundary. That includes stormwater, sewer, and internal drains.

    The exception? If the blockage is clearly in a public main or beyond your property line — that’s when your local council or utility provider steps in.

    How to Avoid Drama

    • Don’t flush wipes, nappies, or hygiene products
    • Avoid tipping grease and food scraps down the sink
    • Install drain guards in showers and sinks
    • Trim trees near underground pipes
    • Get regular drain inspections with a camera (especially in older homes)

    Final Thoughts

    Blocked drains are annoying, but knowing your responsibilities makes things heaps easier. Whether you’re a tenant, landlord, or homeowner, the key is location. If it’s on your turf, you’re likely responsible — but when in doubt, get it inspected.
