Water Heater Servicing

Most storage water heaters, whether it be gas or electric storage systems need to be serviced to keep your hot water running and to mainly prevent a system from shutting down unexpectedly.


A systematic service for residential heaters can range between twelve months to four years for optimal running performance.

Commercial water heaters should generally be serviced annually for peak operation.

Temperature Pressure Relief Valve (TPRV) 

Temperature pressure relief valves are located on a storage water system and are one of the most important parts of a water heater. They are specially designed to relieve the storage water tank of excessive pressure build up during heating cycles. Most manufactures recommend that a TPRV be opened for a few seconds every six months to prevent the valve from seizing or failing. It is important to follow manufactures’ instructions which can be found written on a label near the top of tank.     

Tempering Valves (Hot water mixing valve)

A tempering mixing valve is specially designed to mix the hot water from a hot water heater with cold water, to supply hot water at a consistent temperature.   


These type of valves by law have to be installed on all new hot water heaters that supply hot water to a bathroom to prevent extreme water temperatures that can cause severe scalding. All hot water installations are required to comply with the Plumbing code of Australia. 


By having this valve installed at the hot water system will reduce the chance of scalding in the bathroom at the shower, bath and hand basin.
