Hot water system repairs and fault finding
Repairs and replacements for gas, electric, and instantaneous hot water systems.
Overview
About our hot water system repairs service
Most hot water problems are a failed component rather than a failed system. An element, thermostat, pilot assembly or pressure relief valve can often be replaced for a fraction of the cost of a new unit.
We diagnose and repair gas, electric and instantaneous hot water systems, and we will tell you honestly when a unit has reached the point where replacing it makes more sense than repairing it again.
If a hot water unit is actively leaking, venting continuously, or the water is running dangerously hot, switch it off and treat it as urgent.

When to call us
The signs that point to this service.
No hot water at all
A pilot light that will not stay lit, a tripped element, or a failed thermostat are the usual culprits.
Hot water runs out quickly
Often a failing element or thermostat in a storage system, or sediment reducing the usable tank volume.
Water is rusty or discoloured
Discoloured hot water can indicate corrosion inside the tank, which usually points to replacement rather than repair.
The unit is leaking or constantly venting
Some discharge from the relief valve is normal. A steady stream, or water pooling under the unit, is not.
