Getting the most out of your Geyser
Most manufacturers recommend regular service of geysers in order to prolong the life of the geyser and to prevent scalding. Recommended service is as follows:
- The tempering valve requires replacement every 5 years
- Temperature Pressure Relief valve requires replacement every 5 years
- Anode requires inspection or replacement every 5 years
One aspect of geyser maintenance that you should carry out yourself is checking the correct operation of the Temperature Pressure Relief Valve every 6 months. Correctly operating TPR valves should prevent geysers failing or exploding.
To check the TPR valve (located at top of geyser – check the side of your geyser or user manual for more details), lift the lever for 10 seconds. Water should flow from relief pipe at the bottom of the tank. When you release the lever water flow should stop. This indicates correct operation of the TPR valve. During heating cycles the valve should only release a small amount of water, however continued leaking water in use indicates a fault with the TPR valve. You should contact a qualified professional as soon as possible to investigate and resolve the problem to avoid further damage to your geyser.
Going on Holiday?
If you are going away from home for more than 2 days we suggest you turn off the power and water to your geyser to conserve energy and also to prevent hydrogen gas accumulating in the top of the geyser. Hydrogen gas is a highly flammable gas which if not vented from the system can cause explosions from any appliance connected to the hot water service (for example, washing machines etc).How to prevent a burst water pipe or a burst gas pipe.
As per manufactures guidelines, all stainless steel, rubber flexible pipe connections need to be replaced every 10 years.They are found on basins, toilet cisterns, mixer taps, washing machines, dishwashers, hot water systems, bidets, drinking water systems, gas cook tops, gas ovens, upright gas stoves, and gas room heaters.
