What to Do If Your Geyser Bursts

When faced with a burst geyser that requires emergency service, please contact us without delay. Here are some practical steps to take to avoid consequential damage:


  • Switch off the geyser isolator switch on the main electrical distribution board.
  • Open a hot water tap for a few minutes as it will relieve the pressure from the geyser
  • Turn off the water supply at the water mains.

Malfunctioning Geyser Components

A few typical symptoms of malfunctioning geysers are –

The geyser overflow pipe:

A geyser is fitted with a pressure control valve which often drips on the overflow pipe. An
intermittent drip, caused by water in the geyser heating and cooling, is normal. However, if the
drip becomes continuous, it is a sign that the geyser, or one of its components, is malfunctioning.

Geyser overheating or steam issuing from the overflow pipe:

When a geyser’s thermostat fails, it may cause the water to boil and result in the temperature safety valve opening to prevent the geyser from bursting. This is potentially dangerous and requires the immediate attention of a competent geyser plumber. Switch the geyser off at the electrical main distribution board. Open a hot water tap to allow for the hot water to drain from the geyser while letting in cold water.

No hot water or geyser tripping the electricity:

This is often the result of the geyser thermostat or element malfunctioning.
