Hot water cylinder leaking problems tend to get more calls in Dunedin during the colder months, when cylinders are working harder than usual. If yours has sprung a leak, a few quick steps can limit the damage before help arrives. GoFox Plumbing Dunedin South repairs and replaces hot water cylinders for homes and businesses across Dunedin, Mosgiel and the surrounding area.
What to Do the Moment You Notice a Hot Water Cylinder Leaking
Switch off the power to the cylinder at your switchboard straight away. This comes first, because water and electricity together are genuinely hazardous. Next, turn off the water supply at the isolation valve if it’s safe to reach. Look closely at where the water is actually coming from, whether that’s the pressure relief valve, a fitting, or the cylinder itself. A drip from the relief valve is common. In addition, it’s usually a lower priority than water coming from the tank. Once the area is safe, call a plumber to assess it properly.

Why Dunedin Homes See a Hot Water Cylinder Leaking More Often
Dunedin’s colder climate means hot water cylinders work harder here than in warmer parts of the country. In addition, much of the city’s housing stock is older, including plenty of character villas around Caversham and South Dunedin. As a result, ageing cylinders and original pipework are more prone to wear, corrosion and loose fittings over time. Dan Clarke, who owns GoFox Plumbing Dunedin South, has worked across the South Island for over 20 years. He’s seen this pattern play out in older homes throughout the region.

Repair or Replace?
Not every leak means a full cylinder replacement. For example, a loose fitting or a failing valve is often a straightforward, affordable fix. However, once the tank itself has corroded or cracked, replacement is usually the safer long-term choice. We’ll give you an honest assessment based on your cylinder’s age and condition, not just push for the bigger job.
Hot Water Cylinder FAQs for Dunedin Homeowners
Is a leaking hot water cylinder dangerous? It can be, particularly if water reaches electrical wiring or fittings. Turn off the power at the switchboard first, then call a plumber to check the leak properly.
Is some dripping from the cylinder normal? A small amount from the pressure relief valve can be normal now and then. However, a steady leak or pooling water underneath the cylinder isn’t normal, and it’s worth getting checked.
How long does a hot water cylinder replacement take? Most replacements are completed within a day, depending on your existing setup. We’ll confirm a clear timeframe once we’ve assessed your system.
Do you offer emergency callouts across Dunedin? Yes. We provide after-hours emergency plumbing across Dunedin, Mosgiel and the surrounding districts.
How long do hot water cylinders typically last? Most cylinders last around 10 to 15 years. If yours is approaching that age and starting to leak, replacement is usually the more practical option.
