Margate sits between Woody Point and Redcliffe, with the beach at one end of the street and the Oxley Avenue shops at the other. Most of the housing is mid-century lowset brick and fibro on modest blocks, with a steady run of unit and townhouse infill. Moreton Bay Hot Water is a free referral service that connects you with QBCC-licensed hot water plumbers covering Margate. We are not plumbers ourselves and the referral never costs you anything.
Old tanks in a salt-air suburb
A lot of Margate homes were built between the 1950s and the 1970s, which means the hot water system is often not the original but still not new, sitting on an external wall or in a small laundry with pipework of unknown age. Storage tanks typically last 8 to 12 years, and tanks exposed to salt-laden air near the beach tend to sit at the shorter end of that.
The valves and fittings usually fail before the cylinder does. A weeping relief valve, a rusty base or water marks on the slab are the warning signs worth acting on before the tank splits.
In the newer townhouses and small unit blocks, each lot typically runs its own tank in a cupboard or external nook. Space dictates the size, so a like-for-like swap is the usual path, and anything on common property normally needs body corporate sign-off.
Repair it or replace it
A leaking tank is a replacement. A split cylinder cannot be patched. Elements, thermostats and relief valves on a younger system are often worth fixing, with repairs roughly $150 to $600 depending on the part. See hot water repairs and hot water replacement.
As a guide, electric storage like-for-like swaps run from around $800 to $2,500 installed. Gas storage and continuous flow sit around $1,200 to $3,500 installed where gas is connected, and availability varies street by street. Heat pumps run around $3,000 to $6,000 installed before incentives, with federal certificates taking a chunk off the net price. The cost guide has the full breakdown.
Frequently asked questions
How old is too old for a repair?
Past about ten years on a storage tank, a significant repair is usually money spent on borrowed time. The plumber will give you both numbers, the repair and the replacement, so you can decide.
Can I move the tank to a more sheltered spot?
Often yes, but relocating a unit adds plumbing and sometimes electrical work to the job, so get it priced as part of the quote rather than assumed.
What is the sacrificial anode and does it matter?
It is a rod inside the tank that corrodes instead of the cylinder. Having it checked around year five can extend tank life, and it matters more in a salt-air suburb than inland.
