To ensure clarity and compliance, please review the following conditions that apply to all hot water system pricing listed on this page:
✅ Residential Properties Only: Prices listed apply exclusively to domestic installations. Commercial premises may have different compliance requirements and will be quoted separately.
✅ Installation Assumptions: Prices are based on the assumption that the new hot water system is installed in the exact location and is comparable in size and type to the previous system. All installations are performed to meet current standards, including AS/NZS 3500.4:2025 Heated Water Services and the Plumbing & Drainage Act 2018 (QLD).
✅ Gas and Electrical Compliance: The existing electrical or gas infrastructure must meet current legal standards. If upgrades are required for safety or compliance, additional charges will apply.
✅ Tempering Valve Requirement: Under current regulations, tempering valves are mandatory on all replacement hot water system installations to ensure safe water temperatures.
✅ Relief and Expansion Valve Drainage Compliance: As required by QBCC and AS/NZS 3500, all installations must include relief and cold water expansion valves. These valves must discharge to a compliant stormwater system or an approved household drain. Discharging onto the ground is not legal and will not be performed under any circumstances.
✅ Power Point Installation (Instantaneous Systems): We can provide this service competitively if a new power point is needed to install an instantaneous hot water system. Please contact us for a tailored quote.
✅ Outdoor Installations Only: The pricing provided is for outdoor installations. Additional work may be necessary if an internal system requires replacement and will be quoted accordingly.
AS/NZS 3000:2023 updates the electrical rules. Your new heater must meet them.
When do the new rules apply?
✅ The unit is relocated.
✅ The element size increases, e.g. 2.4 kW to 3.6 kW.
What must be installed?
✅ Safety switch (RCD). Protects people from electric shock.
✅ Weatherproof isolator within arm’s reach. Let anyone cut power instantly.
Who does the work?
Our restricted electrical licence covers disconnecting and reconnecting the heater only. We are not responsible for supplying or fitting the mandatory safety switch or weatherproof isolator. We will advise you of your obligations under AS/NZS 3000 and can arrange a licensed electrician to complete this work. A licensed electrician fits the RCD and isolator when required.
How much will it cost?
Budget $250 – $950 for the extra electrical work. If wiring is non‑compliant, the electrician must fix it before power‑on. This can add cost.

Donna Cushen2024-06-06Trustindex verifies that the original source of the review is Google. We couldn’t have been happier, prompt service and great advice . I can highly recommend them ! David Linnegar2024-04-23Trustindex verifies that the original source of the review is Google. From the initial contact to the plumbers getting out on site the whole process to fix a leak on the propoerty side of the water meter was A plus. Gary was brilliant in answering the multitude of questions via email I sent before we got the visit locked in. Lachy and Ben arrived on site exactly when we were told they would and identified the location of the leak and had it fixed super fast. They even answered questions for me about other works I wanted done to the house so will be reaching out again in the very near future to get the guttering on the whole house replaced. Highly recommend the team! Ben Jones2024-03-12Trustindex verifies that the original source of the review is Google. It is a nice change to deal with a trade group that charges fairly, turns up when they’re supposed to and provides good advice and high quality workmanship. We had a new filter tap, replacement Insinkerator and replacement gas cooktop supplied and installed and we're very happy with the products and the installation. I would have no hesitation in recommending Whywait for your plumbing/gas fitting requirements. Scott GC2024-01-10Trustindex verifies that the original source of the review is Google. I cannot fault the service provided by Gary from Whywait Plumbing Services. He responded early on a Sunday morning to an urgent request to fix a broken tap (which turned out to be quite a complicated repair job) and worked on it until it was completely fixed. I'm extremely grateful for Gary's professionalism and expertise and wouldn't consider calling anyone else. Thank you, Gary!!

Good friendly service, did a great job thanks Keli Magerman2022-12-07Trustindex verifies that the original source of the review is Google.

I was kept up to date via email and phone. And have them booked out again at our new home to install fridge plumbing. I would not hesitate in referring Why Wait Plumbing. Gary was so friendly and efficient! Thanks Again! And see you next week! ✌🏽
