If you’re like most homeowners, you rarely think about your water heater…… “Until there’s a problem”

MOST COMMON GEYSER PROBLEMS AND THEIR CAUSES

1. A Dripping Geyser.

The geyser pressure control valve regulates the pressure inside the geyser so that it stays at a safe level, because a faulty one can cause big problems. Geysers often drip or leak water through the pressure control valve overflow pipe. If you notice that there appears to be a constant stream or that it is dripping very often, it may be a sign that there is a problem. The last sign that there may be trouble includes sudden changes in water pressure, meaning more or less pressure than usual. This often indicates that the pressure valve is not functioning as it should and, if left unchecked, could lead to a geyser burst.

2. Overheating Geyser.

(Steam or hot water escaping from the overflow)

Geyser thermostats are made to fault in the open or “off” position. If the thermostat does this, the geyser stops heating water. Sometimes the thermostat stops functioning in the “on” position, in which case the water will eventually boil, and the geyser may explode. Signs that this is occurring is when hot water and steam is observed coming out of an overflow pipe. The escaping hot water and steam shows that the temperature and pressure valve is releasing hot water because excessive temperature and pressure is building up in the geyser.

The main cause of overheating is a faulty thermostat. This is very dangerous and must be repaired immediately. Switch off the geyser and call a plumber.

3. Water not hot enough or no hot water at all.

Check whether the geyser circuit breaker on the main distribution board has tripped. Only reset the circuit breaker once or twice. If it continues to trip, then call an electrician. If the power supply is stable, but there is still no hot water, this indicates that either the thermostat or the heating element has failed.

GEYSER MAINTENANCE

Regular servicing will increase the lifespan of your geyser. It is suggested that geysers are serviced every three to four years in areas where the water quality is good, and every two years if you have poor quality or hard water. A service involves draining the geyser, checking the magnesium sacrificial anode element and thermostat, and replacing the element and anode if necessary. Lime scale and sludge will be removed from the tank and the entire installation checked for any leaks.

The question is often asked, “at what temperature should I set my geyser?” You can vary your geyser temperature according to the season:

  • 50° to 55°C for summer.
  • 60° to 65°C for winter.
