Hot Water Cylinder Leaking? Steps to Take Right Now
First, turn off the power to your hot water cylinder at the switchboard. This matters even before you touch anything else, because water and electricity together are dangerous. Next, turn off the water supply to the cylinder if you can safely reach the valve. From there, try to work out roughly where the water is coming from. A leak from the pressure relief valve is common. In addition, it’s often less serious than a leak from the tank itself. Once you’ve done this, call a plumber. Don’t wait, because a small drip can turn into a bigger problem quickly.

Common Causes of a Hot Water Cylinder Leaking
A few things typically cause this. The pressure relief valve can wear out over time, and it’s designed to release water if pressure builds up too high. In addition, the cylinder tank itself can corrode or crack with age, particularly in older systems. Loose fittings and connections are another common cause, and these are often straightforward to fix. Occasionally, the issue isn’t the cylinder at all. Instead, it’s a nearby pipe or fitting that just looks like it’s coming from the tank. For a full breakdown of our plumbing services, visit our plumbing services page.
Repair or Replace?
Not every leak means you need a new cylinder. A loose fitting or a faulty valve is often a simple, affordable repair. However, if the tank itself is corroded or cracked, replacement is usually the safer option long term. We’ll assess your cylinder honestly, and let you know which option makes the most sense for your situation and your budget.
Hot Water Cylinder FAQs for South Waikato 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 assess the leak properly.
How much water leaking is considered normal? A small amount of dripping from the pressure relief valve can be normal, especially after the cylinder heats water. However, a steady leak or pooling water isn’t normal, and it’s worth getting checked.
How long does a hot water cylinder replacement take? Most replacements finish within a day, depending on your existing setup. We’ll give you a clear timeframe once we’ve assessed your cylinder.
Do you offer emergency callouts for leaking cylinders? Yes. We provide after-hours emergency plumbing services across Tokoroa, Putāruru, Tirau and the wider South Waikato district.
How old is too old for a hot water cylinder? Most cylinders last around 10 to 15 years, though this varies by type and usage. If yours is approaching that age and leaking, replacement is often the more practical choice.
