A2Z Plumbing Gas And Hotwater
Graham shows up within the hour — including after his last job of the day — to replace failed hot water systems.
Every sample review is five stars, which aligns with the 5-star lifetime average across the full 109, though the small slice we analysed limits how much we can say about consistency across different job types. If your priority is emergency hot water replacement and you want someone who'll explain your choices plainly rather than steer you toward the priciest option, the sample strongly suggests Graham fits that profile — but it's worth asking him directly about his availability in your specific area and any lead times on parts for your preferred system.

About A2Z Plumbing Gas And Hotwater
Graham — the sole operator behind A2Z Plumbing Gas And Hotwater — stands out for his rapid emergency response, showing up within an hour of a call in multiple documented cases and continuing to take jobs into the evening when hot water systems fail outside business hours. His core niche is hot water system replacement: he's fluent in both gas and heat pump options, and reviewers note he walks through the trade-offs between different systems before letting the customer decide, rather than pushing a single solution. He's particularly familiar with the iStore heat pump range, having recommended and installed it across several jobs, and he coordinates the follow-up electrical work through a separate electrician to complete the install cleanly. Beyond hot water, he handles general plumbing repairs — shower pipework and rail installation came up in one job — suggesting he covers the broader residential plumbing scope, not just hot water. He tidies up after himself, including careful removal of rusted or aged systems, which reviewers specifically called out. For homeowners in the northern Perth corridor around Currambine, Graham is a practical first call for after-hours hot water emergencies or situations where you want someone who'll explain your options rather than just sell you the most expensive fix.
Best for: same-day emergency hot water system replacement, homeowners who want options explained before committing to a product, and after-hours plumbing callouts in Perth's northern suburbs.

Does A2Z Plumbing Gas And Hotwater do emergency after-hours callouts?+
Yes — multiple reviewers describe Graham arriving within an hour of being called, including jobs that ran into the evening after his regular last appointment. One customer had their hot water system replaced starting at around 4:30pm on a weekday evening. It's worth calling directly to confirm availability on weekends or public holidays, as that data isn't in the reviews we reviewed.
What hot water systems does Graham install?+
Reviews specifically mention the iStore heat pump hot water system, which Graham has recommended and installed across several jobs. He also works with gas instantaneous systems and electric storage systems, and reviewers note he explains the differences between options — including running costs and suitability — before leaving the choice to the customer. If you have a preference or want a comparison, he appears comfortable advising on it.
Is A2Z Plumbing a solo operator or does he have a team?+
Graham runs A2Z as a sole trader, so you're dealing with the same person from the initial call through to the completed install. Reviews consistently reference Graham by name as the person who attends, advises, and completes the work. For jobs requiring electrical connections — such as heat pump installations — he coordinates a separate licensed electrician to handle that component.
What areas does A2Z Plumbing Gas And Hotwater service?+
The business is based in Currambine in Perth's northern suburbs. Reviews don't detail the exact service radius, so if you're outside the immediate northern corridor — Joondalup, Clarkson, Butler and nearby suburbs — it's worth confirming with Graham directly whether he covers your area before booking.
What do customers say about Graham's communication and workmanship?+
Across the reviews we analysed, customers specifically praise Graham for explaining their options clearly without pushing a particular product, arriving promptly, and leaving the job site clean — including careful removal of old, rusted systems. One reviewer noted the follow-up electrician arrived the next day without any fuss, suggesting the coordination between tradespeople is smooth. No concerns about communication or workmanship appeared in the sample we reviewed.
