Although your geyser is out of sight, it should never be out of mind. Geysers require a certain amount of low-level maintenance to prevent the progress of more serious plumbing and structural problems.
If your geyser is not maintained properly, it could be driving up your electricity bill or wasting precious water. Even worse, considering that the average overhead geyser easily packs energy equivalent to half a kilogram of dynamite, it could also pose danger to your family and precious belongings. Thus, regular geyser management is important. In this article we will show you what to look for with a few hot hints to keep your problems from overflowing.
A QUICK GEYSER TROUBLESHOOTING GUIDE:
No hot water - First step is to check your DB board to see if the geyser circuit breaker has tripped. Only reset the switch once or twice, if it keeps tripping then call an electrician. If the power supply is ok however, then this indicates that either the thermostat or the heating element has failed. Both should be replaced simultaneously, and a plumber will be able to help with this.
Water not hot enough - Either the setting on the thermostat is too low or the thermostat / element is malfunctioning. If it’s an old geyser it might have become calcified and inefficient, in which case it should be replaced. However, never set the thermostat above 70ºC, this will minimise chances of rupturing due to pressure build should the pressure valves fail.
IDEAL SETTINGS: ± 50ºC in Summer and ± 60ºC in Winter.
Poor pressure on hot water - It could be ascribed to a number of things. One cause could be that old galvanised pipes or a valve has become blocked. Some houses still have older low-pressure geysers, which do not have modern pressure balancing valves installed. This valve ensures that the cold and hot water supply is equal.
Water leaking through the ceiling - Either the geyser has burst, or a major leak has developed and the drip tray and overflow system is not coping. Immediately switch off the power supply to the geyser as well as the cold water supply, then call a plumber.
Dripping overflow - It’s not unusual for the overflow pipe to drip moderately from time to time, as the water in the geyser heats and cools. If dripping is excessive however, it means the overflow valve is faulty and needs to be replaced.
A LAST FEW HOT HINTS:
Switch off your geyser if it will go unused for extended periods of time. When going away on holiday, or won’t be using it for more than 12 hours, switch it off at the DB board and then isolate the water supply feeding the tank. This will drastically reduce your electricity bill.
Ensure that your geyser’s thermostat and element are under a protective cover, as these are often left lying next to the geyser by unprofessional installers.
Ensure that your geyser is fitted with the appropriate piping. The pipe feeding directly into and out of the geyser should be copper, but the connecting pipes can be plastic. Want to know more about plumbing pipes? Read our DIYer’s guide here.
It is advisable to have your geyser serviced every 3 - 4 years where the water supply is good quality and every 2 years where the water supply quality is bad.
Insulate your geyser with a geyser blanket, to prevent heat loss and reduce the cost of electricity in keeping the water hot. Watch our handy video on how to install a geyser blanket here
