Tenant vs Landlord: Who Pays for Water Leak Damage in a Perth Rental?

A $2,000 water bill lands on a rental property. The pipe is leaking under the lawn, or inside a wall. The property manager forwards the bill to the tenant, and the tenant says it isn’t theirs.

This guide sets out who pays for what under WA law, when a tenant can end up liable, and how to sort it out without a fight. It’s written for tenants, landlords and property managers.

The short answer

For a leak caused by the plumbing itself, the landlord pays for the repair and the water lost. The tenant pays for the water they actually use. This is the default position under the Residential Tenancies Act 1987 (WA) and Water Corporation’s own guidance.

The tenant pays only if they, their guests or their pets caused the damage.

A leak creates four separate costs

Most arguments happen because these costs get lumped together. Separate them and the answer usually becomes clear.

When the tenant can end up paying

The tenant is responsible when they, their guests or pets cause the damage (section 38). Fair wear and tear doesn’t count.

Warning: A tenant also has a duty to tell the landlord about damage. If you knew about a leak and sat on it for weeks, expect the landlord to argue that the extra water lost is on you. Report it the day you notice it, and do it in writing.

Retic leaks: the grey area

Retic is where most Perth rental disputes start. Many leases make the tenant responsible for garden watering, so the tenant pays the water the retic uses.

A broken pipe buried under the lawn is different. It’s part of the property’s plumbing, so repairing it sits with the landlord. A visibly broken sprinkler head that the tenant never reported is harder to argue. Check what your lease says about gardens and retic, and read underground pipe leak vs retic leak to work out which one you have.

A burst or leaking pipe is an urgent repair

Water supply is an essential service under WA tenancy law. Once the tenant reports it, the landlord has 24 hours to organise a repairer. Other urgent repairs, such as a leak that could damage the home, must be organised within 48 hours.

If the landlord or property manager doesn’t respond, the tenant can organise the repair themselves:

The landlord must reimburse reasonable costs. If they don’t, the tenant can apply to the Magistrates Court. Tenants must keep paying rent while waiting for a repair.

What about the Water Corp leak allowance?

The Water Corporation Leak Allowance can credit up to 50% of the estimated water lost from a hidden leak. In a rental, the property owner or property manager usually applies, because the account is in the owner’s name. The repair must be done by a licensed plumber within 60 days, and the application lodged within 6 months of the repair.

Important for tenants: the allowance is a matter between the owner and Water Corporation. If the landlord’s application is refused, or they never apply, the leak’s water doesn’t shift onto you. Water Corporation’s position is that the owner bears the cost of water lost through a leak.

For landlords, the allowance depends on paperwork. You need an itemised invoice from a licensed plumber stating what the leak was and where. Our Water Corporation Leak Allowance guide covers every requirement.

The bill notice rule landlords often miss

Warning: If the landlord passes on water use charges themselves, they must send the tenant a written notice within 30 days of receiving the bill. It must show the meter reading, the charge per unit and the total. If the notice is late, the tenant doesn’t have to pay it.

How we help with rental leaks

Rental leaks go badly when they drag on. A property manager books one trade to find the leak and another to fix it. Weeks go by, and the water bill keeps climbing.

We find and fix the leak in one visit, at a fixed price agreed before we start. Every job comes with an itemised invoice that states the location and nature of the leak, plus photos. That’s the documentation Water Corporation asks for, and it gives both sides a clear record of what failed and why.

Frequently asked questions

My landlord wants me to pay the whole water bill after a leak. Do I have to?

Not for the leak itself. You’re responsible for the water you use. The water lost through a leak in the property’s plumbing is the owner’s cost, unless you caused it. Pay your normal usage and dispute the rest in writing.

Who pays the plumber if I organise an urgent leak repair myself?

The landlord, provided you tried to contact them first, used a licensed plumber and kept the repair to what was needed. Send them the itemised invoice. If they refuse, you can apply to the Magistrates Court.

Does the landlord’s insurance cover my belongings?

No. Landlord insurance covers the building and the landlord’s own contents. Your belongings need your own contents insurance. Our guide to water leak damage insurance claims explains what to document.

Can a tenant apply for the Water Corp leak allowance?

In most rentals the owner or property manager applies, as the account is in the owner’s name. The allowance is credited to that account. Either way, the leak’s water is the owner’s cost.

I didn’t notice the leak for two months. Am I liable?

Not simply for failing to notice a hidden leak. Hidden leaks are hidden, and many only show up on the bill. The risk comes if you knew about a problem and didn’t report it.
