Supply, installation, replacement and repair of hot water cylinders across every Hamilton suburb. Same-day replacement on common sizes. PGDB-licensed plumbers and gasfitters.
A failed hot water cylinder is the kind of plumbing problem that goes from inconvenient to flooding-the-cupboard fast. Most Hamilton homeowners only think about their cylinder when it stops working — which is usually when it’s leaking, the recovery is so slow that showers are cold by 7am, or there’s rust water coming out of the hot taps.
Plumbway Ltd is based in Hamilton and carries out hot water cylinder work as a regular part of our service. We hold the common sizes and brands in stock, so for most failed cylinders we can do a same-day replacement if you call early enough. We’re PGDB-licensed plumbers and gasfitters, so we handle both electric cylinders and gas-fed systems (storage or continuous flow) under one licence.
If you’re seeing any of these on an older cylinder, don’t wait for it to flood the house:
Recovery time is degrading — usually a failing element on an electric cylinder, or burner/sensor issues on gas.
Sign the internal tank is corroding. Generally a cylinder past this point should be replaced, not patched.
The tank is leaking — usually terminal. Call us before it becomes a flooded cupboard or ceiling.
Sediment buildup inside the tank, or pressure issues. May be serviceable, may indicate replacement is near.
An aging cylinder runs less efficiently. A modern replacement often pays back the upgrade in reduced power use.
Many Hamilton homes still have original cylinders well past warranty. Replacing proactively beats an emergency callout.

Call 022 453 5783For most failed cylinders in Hamilton we can carry out a same-day or next-day replacement. We hold common cylinder sizes and brands in stock on our vans, and being Hamilton-based means we can attend quickly. Call us as early in the day as possible — we'll confirm what's available and book you in.
We install electric storage cylinders (mains and low-pressure), gas storage cylinders, gas continuous flow (instantaneous) units, and solar-compatible cylinders. Common brands we work with include Rheem, Rinnai, Bosch, Bradford and others. The right choice depends on your hot water demand, gas availability at your Hamilton address, and the existing pipework — we'll talk you through the options before you commit.
A typical electric storage cylinder lasts 15–25 years, depending on water quality and maintenance. Hamilton's town water is generally good quality, but older Hamilton homes (Hamilton East, Frankton, Claudelands) often still have original cylinders well past their warranty period. If your cylinder is over 15 years old and showing signs of failure — rust at the base, fluctuating temperature, slow recovery, weeping fittings — replacement is usually more cost-effective than repair.
Yes. As well as hot water cylinders, we install rainwater storage tanks, header tanks and pressure-fed water tank systems for both town and lifestyle properties. For rural Hamilton-fringe properties without reticulated water, this often includes pump installation and pressure system setup.
Insurance typically covers the consequential water damage from a burst cylinder — flooring, walls, ceiling — but doesn't usually cover the replacement cylinder itself, which is treated as a wear-and-tear item. Worth checking your specific policy. We can provide an itemised invoice for any insurance claim relating to the water damage.
Same-day replacement available on common sizes. Call us as early as you can.
