Signs your cylinder needs replacing, not repairing

Cylinders don't usually fail without warning. Watch for:

Rusty or discoloured water coming from the hot tap
A cylinder older than 10 to 15 years, especially an original unlined steel tank
Water pooling around the base of the cylinder
A popping or rumbling sound from the cylinder as it heats
Hot water running out faster than it used to, even with normal use

A repair can fix a faulty element or thermostat. It can't fix a tank that's rusting from the inside, and once that starts, replacement is the only real option before it fails completely, usually at the worst possible time.

Why replace with Rheem

As an accredited Rheem Service Centre, we install and service Rheem cylinders to the manufacturer's own standard, which keeps the warranty valid and gives you a direct line to Rheem support if anything goes wrong later. Rheem's New Zealand-built cylinders are designed for local water conditions, and the range covers most Wellington homes:

Mains pressure cylinders for standard household use, in a range of sizes
Low pressure cylinders for older villas and homes without mains pressure plumbing
Continuous flow gas systems for homes wanting hot water on demand rather than a stored tank
Heat pump cylinders for households prioritising running cost over upfront price

We'll size and recommend based on your household, not just swap in whatever's closest to the old cylinder's dimensions.

The 3-Step Success Plan

Our streamlined process ensures your Rheem hot water system is repaired or replaced with minimal disruption to your day.

Assessment. We check your current cylinder, pipework and pressure type on-site, and confirm mains pressure or low pressure.
Sizing. Cylinder size is based on your household size and hot water use, not guesswork. A cylinder that's too small means cold showers by evening. Too large wastes energy.
Same-day install. Most straight swaps, same fuel type and similar size, are completed in a single visit. Conversions between gas, electric or heat pump may need a second visit for additional pipework or wiring.

All work meets current Building Code and Rheem installation standards, and we'll leave you with the paperwork your warranty needs.

Frequently Asked Questions

How do I know if my cylinder needs replacing or just repairing?

Rust in the hot water, popping sounds, or water pooling at the base usually mean the tank itself is failing, which repair can't fix. A faulty element, thermostat or valve can often be repaired instead. We'll tell you honestly which one it is before recommending a replacement.

Can you replace my cylinder the same day?

Yes, for most straight swaps where the new cylinder matches the existing fuel type and size. Conversions between fuel types or a change in pressure system may need a second visit.

Does using an accredited Rheem Service Centre matter for my warranty?

Yes. Installation by an accredited Rheem Service Centre keeps your manufacturer's warranty valid and gives you direct access to Rheem's own support and parts network if an issue comes up later.

What size cylinder do I need?

It depends on your household size, number of bathrooms and hot water habits. We'll size it properly on-site rather than matching the old cylinder's dimensions, since the original may have been undersized to begin with.

Do you handle gas and electric conversions, not just like-for-like swaps?

Yes. We can convert between electric, gas and heat pump systems, though these typically need a second visit for additional pipework, wiring or venting.
