We cover all of Wooloowin and the suburbs around it, from the interwar Queenslanders to the units east of the railway line.

Hot Water Not Working but Cold Is Fine
The checks run in a set order. We start with the cold supply and its isolation valve, then look for leaks around the unit. Next comes whether the hot water is gone at one fixture or everywhere, then the gas or power supply, and finally the delivery temperature.
Here is what each check tells us:
Cold supply
the isolation valve on the inlet side has to be open, and cold water has to be reaching the unit before anything else matters.
Leaks
we inspect the tank, the joints, every valve and the relief line for water, because a small weep often explains a big drop in supply.
One fixture or all of them
hot water missing at a single outlet usually means the fault sits at that fixture itself. Hot water missing everywhere points to the system, the water feeding it, or the valves on it.
Gas or power
on a gas unit we confirm the supply is arriving, and we shut the gas off safely at the meter if a leak is suspected.
Delivery temperature
we measure the temperature at the outlet to see whether the fault is volume, heat, or both.
Our diagnosis stays on the water side of the system: the pipes, the valves and, on a gas unit, the gas supply. Electrical fault finding sits outside a plumbing visit, and we say so plainly when we reach that line.

Signs a Hot Water System Is Past Repair
The repair-or-replace line comes down to where the water appears. Valves, fittings and joints are fixable, but a leak through the body of the storage tank means the tank is finished, and the whole system gets replaced.
A few things feed the same decision:
The unit's age and its service record
an older system with no service history gets a harder look than a recently serviced one.
Servicing guidance
the QBCC points to servicing roughly every five years by a licensed person, and sooner on bore or tank water, though that spacing is a recommendation rather than a rule.
Repeat faults
when an ageing system throws the same fault twice in one season, a replacement is usually the better call than a third repair.

Temperature Control Devices and When They Are Needed
Temperature control devices keep the water delivered to residential taps at or below 50°C, while a storage system holds its water at 60°C or hotter. That cooler delivery temperature handles household hygiene and cuts the scalding risk, and the hotter storage temperature keeps Legionella bacteria from multiplying.
A device is required in these situations:
- any new hot water system, and any replacement, including a straight like-for-like swap
- a new fixture meant mainly for washing people, such as a shower, which also brings in our bathroom plumbing work
- changing a washer or a shower head does not trigger one, because those are simple swaps at an existing fixture
A thermostatic mixing valve, one common type, is serviced only by a licensed plumber holding the right endorsement.

Who Can Replace a Hot Water System
Replacing a hot water system is work for a licensed plumber, and a gas unit also brings a licensed gasfitter onto the job for the gas side. Because water heaters are regulated work, the licence is the whole story.
For an existing building, this work sits in the notifiable class:
- no permit from council and no compulsory inspections apply
- Wooloowin Plumbing Services lodges a Form 4 with the QBCC within ten business days of completing the job
- you receive a copy of that notice for yourself

Hot Water in a Suburb of Mixed Vintages
At the last census this suburb counted 784 separate houses against 816 flats and apartments, and that split shapes the hot water work we do. The interwar Queenslanders mostly run tanks that have been swapped two or three times in the same spot beside the house. When the cool season arrives, those older units are the calls we take first.
Dual dwellings have replaced some of the old houses, and those blocks carry water heaters from mixed generations. A single street off Dickson Street or Bridge Street can hold one unit at the end of its life next to another barely run in, so we never assume age before we look.
A cold shower before work counts as urgent for plenty of households, and our emergency plumber page sets out what qualifies. Gas units bring their own rules, which our gas fitting page covers in full.

Hot Water Questions From Wooloowin Homes
Call (07) 3523 7172Why have I got cold water but no hot water in my Wooloowin home?
Where the hot water has disappeared to tells us where to look. One cold tap points to a fault at that fixture or its mixer. Every tap running cold points back to the system, the water feeding it, or the valves on it, so we work through the checks in order.
What temperature should hot water be at the tap?
In a home, no more than 50°C. A temperature control device holds delivery at that ceiling, while storage water is held at 60°C or above to keep Legionella bacteria in check.
How often should a hot water system be serviced?
The QBCC recommends servicing roughly every five years by a licensed person, and sooner where the supply is bore or tank water. That interval is a recommendation, not a legal limit.
Is no hot water an emergency for a tenant?
Yes, Queensland tenancy law treats a failed hot water service as an emergency repair. The tenant contacts the emergency contact listed on the tenancy agreement, and the fault gets handled as an urgent job.
What decides the cost of hot water repairs in Wooloowin?
The price comes down to two drivers, namely the part that has failed and whether the job involves a gas system or a temperature control device. Your fixed quote confirms the figure before any work starts.
