In the motor vehicle industry 30 years back most vehicles were heavy and big. The only safety precaution to help prevent serious injury was the safety belt. 30 Years down the line vehicles are lighter, smaller and they are more compact with extra safety features like airbags, traction control and ABS breaking. These safety measures are to prevent serious accidents and less fatality.
In the Plumbing Industry 30 years ago the hot water cylinders were only manufactured from copper. These units were combination (gravity feed) and later semi pressure units. The life expectancy of these geysers were anything from 10 to 30 years. The minimum safety requirement that prevented damages to the property was a drip tray. Now 30 years down the line as the industry has changed from semi pressure to high pressure geyser, the manufacturing material most commonly used is steel.
These geysers operate under high pressure, mostly 400kpa and 600kpa. It is not surprising that the pressure of the geyser together with the inferior material (steel) and construction processes eventually result into burst geysers. The average lifespan of a steel geyser is between 5 and 10 years. After 30 years, the minimum requirement to prevent damages to a clients’ property is still just a drip tray. It makes you think why 70% of claims on home owners insurance policies that gets reported are geyser related.
Leaks often occur on hot water vacuum breakers which are not directly over the drip tray. This often causes water to spray outside the drip tray thereby bypassing the overflow.
Below you will find some photos that illustrate the damage that a burst geyser can cause to a home, office or factory. In most cases there was damage to the ceiling and walls that had to be repaired. This usually involves replacing the ceiling and painting the walls and the ceiling. Often there are damages to wooden flooring, carpets as well as cupboards.
