Bursting of a geyser might be referred to as breaking or causing the geyser to break open abruptly and loudly, particularly due to increase in internal pressure. Geysers do not generally burst or explode. They, in due course of time, give in due to corrosion. Let us have a look at various causes of burst geyser.
* One of the causes might be due to the increase in pressure or temperature in the geyser by a large margin beyond its specifications. This would generally happen due to the failure in the thermostat leading to the heating up of the geyser up to the boiling point.
* When the geyser pressure vessel gives in due to the absence of maintenance, it might cause geyser burst. Normally, a sacrificial anode is fitted inside a mild steel geyser. In order to inhibit corrosion, this sacrificial anode has to be replaced at regular intervals. When this regular maintenance is not carried out, the hot water will speed up the rate of corrosion, particularly in the areas surrounding the element and the hot water vent.

* The use of inferior quality materials to ensure a cost effective product might result in leaks due to poor construction and substandard materials used. At times, when you add multiple outlets and valves and several connection points, leaks seem unavoidable.
* Generally, contraction and expansion of the geyser tank and its related structure occur during normal usage as the used hot water is replaced by cold water. During the winter, the temperature of cold water might be considerably lower. So, the temperature difference between the hot water leaving the geyser and the entering cold water is much greater as compared to that during summer. This might lead to metal fatigue due to increase in the rate of expansion and contraction.
* Sometimes, there might be a vacuum collapse in which case the vacuum breakers inside the geyser fail due to the creation of a vacuum. This might not be considered as a burst but a collapse.
The major causes for geyser failures might be listed as follows:
* Very high temperatures
* Corrosion due to absence of maintenance
* The use of low-cost materials in geysers as opposed to using more corrosion-resistant materials like copper and stainless steel options
The most common areas where leaks occur are:
* The geyser hot and cold water inlets
* At the vacuum and safety valve breakers
* At the geyser fittings
* Around the pressure reducing valve
* The joints and layers of the geyser
In case your geyser bursts, you must immediately turn off the water mains and switch of the electricity, and contact your plumber.
