FAQs
Why do I need a licensed plumber to work on my tank water heater in Mascot?
Under NSW Fair Trading regulations, any installation, replacement or major repair of a storage tank water heater must be carried out by a licensed plumber. A licensed technician ensures the work meets Australian Standards (AS/NZS 3500 for plumbing and AS/NZS 5601 for gas), protects your manufacturer’s warranty, and guarantees the compliance certificate you’ll need if you ever sell or rent the property. Our Mascot-based plumbers hold current NSW plumbing, gas-fitting and electrical disconnect/reconnect licences and carry $20 million public-liability insurance for your peace of mind.
What signs indicate my tank water heater needs repair or replacement?
Common warning signs include: (1) rusty-coloured or metallic-tasting hot water, (2) rumbling or popping noises caused by sediment buildup, (3) water pooling around the base of the cylinder, (4) inconsistent or rapidly cooling hot-water supply and (5) visible corrosion on fittings or the tank shell. If your unit is over 8–10 years old and showing any of these symptoms, call our Mascot team for an inspection. We can often flush the tank, replace sacrificial anodes or thermostats, but if the cylinder itself is leaking, replacement is the safest and most economical option.
How long should a storage tank water heater last?
With regular maintenance, a quality glass-lined steel tank typically lasts 8–12 years in Sydney’s water conditions. Stainless-steel models can reach 15 years. Factors that shorten lifespan include high sediment levels, skipped anode replacement, and water pressure above 500 kPa. We offer annual servicing that includes temperature-pressure relief (TPR) valve testing, anode inspection, and a full system flush, which can add several years to your heater’s service life.
What does a new tank water heater installation cost in Mascot?
Prices vary with capacity (25 L to 400 L), energy source (electric, gas, heat-pump hybrid) and site requirements. As a guide: replacing a like-for-like 50 L electric indoor unit starts from $980 fully installed, while a 135 L external gas storage system typically ranges $1,650–$2,100. Costs include the new cylinder, labor by a licensed plumber-gasfitter, valves, pipework, tempering valve, disposal of the old unit and a Compliance Certificate. We provide fixed-price quotes after a free on-site assessment in Mascot and surrounding suburbs.
Can you convert my existing electric tank heater to gas, and what is involved?
Yes. Converting to natural gas can lower running costs by up to 60 % and free up off-peak electricity for other appliances. The process involves (1) checking gas supply capacity and meter location, (2) running new copper gas lines with isolation valves, (3) installing a flue or ensuring outdoor positioning for ventilation, (4) fitting the new gas storage tank, and (5) lodging a gas compliance certificate. Average turnaround is one day, and our team handles all excavation, trenching and concrete coring if required.
How can I improve the energy efficiency of my existing tank water heater?
Simple upgrades include lowering the thermostat to 60 °C (the minimum safe legionella-control temperature), insulating the first 2 m of hot-water piping, and scheduling a six-monthly sediment flush to improve heat transfer. Replacing a worn sacrificial anode reduces corrosion and heat loss, and fitting a timer to electric models allows charging during off-peak hours. Ask our Mascot plumbers about installing a tempering valve and mixing cold water at the outlet—this lets you store water hotter for efficiency while delivering safe 50 °C water to taps.
