If a hot water cylinder starts to leak, what should be done first?

When a hot water cylinder begins to leak, the first priority must always be safety and preventing further damage. Isolating the power and water supply is crucial because it stops the flow of water, reducing the risk of flooding or additional leaks. This action also protects the electrical components of the system from potential water damage, which could pose a safety hazard if the leak is severe.

Once the power and water have been isolated, it is safe to assess the situation further, call a qualified plumber, and explore repair options. By handling the power and water supply first, one can mitigate immediate risks and avoid escalating the problem, ensuring a more controlled approach to resolving the leak.
