Blocked drain in a rental: landlord or tenant pays?

Updated October 2026

In NSW the landlord is generally responsible for blocked drains caused by wear and tear, tree roots or broken pipes. The tenant usually pays if they caused it, for example by flushing wipes or putting fat down the sink.

Urgent repairs

Under the NSW Residential Tenancies Act 2010, a blocked or broken toilet system is an urgent repair. If the landlord or agent can't be reached, a tenant can arrange the repair and claim reasonable costs back, within the limits the law sets.

Who caused it decides who pays

  • Tree roots, cracked pipes and old clay lines: landlord.
  • Wipes, sanitary items, fat or objects flushed by the tenant: tenant.
  • A CCTV report showing the cause is the simplest way to settle it.

Check the current rules

Limits and processes change. Check the NSW Fair Trading website for the current urgent repair rules before you pay.
