Leaking Water Heater Emergency Guide

Stay Calm. Protect Your Home.

A leaking water heater can quickly cause water damage and may indicate a fault that requires professional attention.

This guide explains how to make the situation safe, reduce water damage and know when to call a qualified plumber.

Step-by-Step Guide

Step 1 – Switch Off the Water Heater

If it is safe to do so, switch off the water heater using its power controls.

Do not attempt to dismantle or repair the appliance yourself.

Step 2 – Turn Off the Water Supply

Turn off the water supply to the water heater. If you are unsure, turn off your property's main stop valve.

Step 3 – Contain the Water

Place towels, buckets or FloodFort flood bags around the leak to help prevent water spreading across the floor.

Protect nearby flooring, cupboards and belongings where possible.

Step 4 – Check for Obvious Leaks

Look for water leaking from pipe connections, valves or the base of the water heater.

Do not remove any covers or attempt repairs.

Step 5 – Contact a Qualified Plumber

Arrange for a qualified plumber to inspect and repair the water heater before using it again.

FloodFort Tip

Keep your FloodFort Kit somewhere easy to access so you can respond quickly to unexpected water emergencies.

Using FloodFort flood bags early can help minimise water damage while you wait for repairs.

Need More Help?

If water has reached electrical wiring or fittings, switch off the electricity at the consumer unit if it is safe to do so.

If the leak is severe or you cannot stop the water supply, contact an emergency plumber immediately.
