Why service your Perth hot water system?

Perth’s water is high in mineral content which has a negative effect on your hot water system. The water causes build-ups of corrosion and rust which cause the relief valves, anodes, pressure limiting valve, tempering valve, isolation non-return valve, thermostat, thermocouple or the element to fail.

The longevity of the storage tank is highly dependent on a sacrificial anode, the anode is a metal rod constructed from aluminium or magnesium, and coated in zinc. The anode is inside your hot water tank, it attracts impurities and minerals in the water which can potentially cause rusting and/or deterioration to the tank which can lead to the tank rupturing.

When a storage hot water system is heating – the water expands and turns to steam which increases the pressure in the tank and must be relieved through the relief valve. The two relief valves found on storage hot water system including solar systems are the PTR (Pressure Temperature Relief Valve) and ECV (Expansion Control Valve). These valves must be opened every 6 months to ensure the valves are not ceased.
