Hot Water System Replacement in Sydney
There's a rust stain and a wet patch under the tank in the garage, and once a cylinder starts weeping at the seam, no part will stop it.

Questions and answers
Most like-for-like swaps are finished the same day, with the water off for a few hours while the old tank drains and the new one goes in. A change of fuel or position can take longer, and we'll tell you before the day.
The type and size of the new unit, how easy the spot is to reach, what the code needs fitted and whether gas or power has to change all move the figure. You get it in writing before any work starts.
No. We supply the unit as part of the job, so the tank, the fitting, the valves and the removal of the old one come as one written price, with one number to ring if anything isn't right.
Under the NSW Energy Savings Scheme, eligible heat pump and solar upgrades can attract a discount, and the scheme says it is provided upfront in the installation quote. Eligibility is set by the scheme's rules, not by the plumber, so check whether your upgrade qualifies before you count on it.
NSW guidance is clear that a temperature control device, meaning a tempering valve or a thermostatic mixing valve, goes in when a hot water heater is replaced, unless the new unit is a factory pre-set type. We check the existing one and fit a new one where it's needed.
We drain it, disconnect it and take it away on the day. We take the mess with us when we go.
