Blocked Drains in a Rental: Tenant or Landlord?

Updated July 2026 · 7 min read · Geelong Emergency Plumbing

A blocked drain in a rental property is one of those situations that exposes the gap between what the Residential Tenancies Act says and what everyone assumes. The short answer — it depends on the cause — sounds unhelpful until you understand the framework, at which point most disputes become straightforward. Here's the rule set, the urgent-repair escalation path, and what documentation protects both sides.

The Core Principle: Cause Determines Responsibility

Under Victorian tenancy law (and broadly across Australian jurisdictions), landlords are responsible for maintaining the property in good repair — including functional drainage. Tenants are responsible for damage they cause or that results from their use of the property. Applied to blocked drains, this means:

• Landlord's problem: tree roots in ageing clay pipes (wear and tear), a collapsed or failing drain (structural), a drain that was already compromised before the tenancy began, and anything below ground that isn't connected to how the tenant used the property.
• Tenant's problem: a blockage demonstrably caused by what the tenant flushed, poured or put down the drain — wipes, grease build-up from heavy cooking without basic maintenance, foreign objects, improper disposal.
• Grey zone: a grease blockage in a property where the pipes were already marginal and a moderate amount of normal cooking created a problem. Plumber's written report on the cause matters here.

Victorian Urgent Repair Rules

Under the Residential Tenancies Act 1997 (Victoria), blocked or broken toilets and failure of essential services are listed as urgent repairs. The procedure:

1. Contact the agent or landlord first. Use the emergency contact number on your tenancy agreement. Try both a call and a written message (text or email) and document the time.
2. If no response after a reasonable attempt, tenants can arrange and pay for urgent repairs up to the threshold set in the Act (confirm current amount, as it adjusts — the Consumer Affairs Victoria website carries the current figure).
3. Give written notice within 24 hours of arranging the repair, and keep all receipts.
4. The landlord must reimburse within 7 days for valid urgent repairs by a licensed tradesperson (which is why DIY doesn't qualify for reimbursement).

Licensed plumber, documented contact attempts, written notice, receipts: these four elements make reimbursement a procedure rather than a dispute.

The Plumber's Report Is the Evidence

Whether you're a tenant seeking reimbursement or a landlord disputing a charge, the plumber's written report on the cause of the blockage is the critical document. "Tree roots in 1970s earthenware pipe at 3.5 metres" is a landlord issue. "Foreign object consistent with baby wipes in the first metre of drain" is a tenant-use issue. CCTV footage as evidence is stronger again. Request a written cause-and-location report from whoever does the work — it costs nothing extra and is the difference between a clear resolution and an argument.

For Landlords: The Practical Calculus

Older rental properties in established Geelong suburbs with mature trees are virtually certain to develop root intrusion in the drainage over time — it's property maintenance, not tenant misuse. Arguing root-blockage costs with tenants is a dispute that typically costs more in time and tribunal fees than the plumber's bill. Where root intrusion is recurring, a CCTV inspection and pipe reline is the landlord investment that ends the cycle: no more quarterly emergency calls, no more tenant complaints, no more tribunal risk. Our inspection guide and relining cost guide cover the numbers.

For Tenants: Protecting Yourself

Document the blockage with photos and video before any clearing happens — the condition before work is your evidence. Follow the contact-document-notify procedure before paying for repairs, because verbal "we'll sort it out" promises disappear. And if the cause is genuinely ambiguous — old pipes plus your use — the plumber's honest assessment in writing is your best route to a fair outcome rather than a disputed one.

And a closing note for both parties: most landlord-tenant blocked-drain disputes are resolved by the plumber's report, not by tribunal. A clear written cause finding from a licensed plumber — especially with CCTV footage — makes the responsible party's position factual rather than argued. The cost of obtaining that report is trivial compared to the cost of a VCAT hearing, and both sides benefit from a resolved dispute rather than an extended one. Getting the camera run and the written report is the investment that prevents the argument rather than losing it.
