About hot water system work
Hot water issues occur in homes and commercial sites across greater Melbourne. Whether a system is not heating, a cylinder is leaking or a tenancy has no hot water, you need a licensed plumber who can assess the issue, explain the options and quote the repair or replacement.
Plumstar repairs and replaces domestic and commercial hot water systems. We confirm the address, inspect the unit and surrounding pipework, and explain what is required and what it will cost before additional work starts. If there is a leaking unit, isolating the issue and making the property safe comes first. Any further repair or replacement is discussed and priced before proceeding.
Private owners, real estates, body corporates and facility managers work with the same licensed team. Planned replacements are scheduled around the property requirements and builder’s program.
Call (03) 9408 8664 if your hot water system needs repair, replacement or assessment. All completed work is backed by our guarantee

What to expect
You get a licensed plumber, a clear explanation of the issue and pricing before parts are ordered or additional work begins. Nothing proceeds with a repair or replacement until you understand the options and agree on the next step.
We discuss the issue over the phone
Tell us whether there is a leak, no hot water, inconsistent heating or unusual noises from the unit. We’ll arrange a suitable time to attend based on the property requirements. If water is escaping from the tank or system, let us know during the call so we can prioritise the leak.
We diagnose on site
The plumber inspects the unit, isolation valves and connections, then explains what they have found in plain English. You understand whether a repair is suitable or whether replacement may be the better option before any new system is ordered.
You choose repair or replace
We provide repair and replacement options where both are suitable, with clear pricing so you can decide how to proceed. If there is a leaking tank, isolating the issue and making the property safe comes first. Once the approach is agreed, the work proceeds based on the scope discussed on site.
We restore hot water and guarantee the work
Once approved, we complete the work, test the system and confirm everything is operating as expected. All work completed by Plumstar is backed by our guarantee. If an issue arises with a repair or replacement we have carried out that is covered under the guarantee, we return to assess the problem and complete the required repairs.
