If you are talking about the little rod that melts causing the sprinkler to spray water, it is not an element. It is either a metal alloy or plastic that melts at a relatively low temperature. The older sprinklers all used metal alloy, but as the usual alloy contained lead as one of the metals that alloy has been phased out due to concern over toxicity. Where metal alloy is still used it has been reformulated without lead. But the preference now is to use plastic rods.

What kind of sprinklers do not need melting to set it off?

Sprinklers that do not need melting to activate are called "fusible link sprinklers." Instead of relying on heat to melt a fusible link, these sprinklers have a heat-sensitive element that responds to a certain temperature, causing the sprinkler to activate and release water.


Why is the use of overhead sprinklers for irrigation inefficiencent?

Overhead sprinklers for irrigation are inefficient primarily due to evaporation and wind drift, which can result in significant water loss before it reaches the ground. Additionally, they often lead to uneven water distribution and may overwater some areas while leaving others dry. This inefficiency can increase water waste and reduce the overall effectiveness of irrigation efforts.


Should fusible link sprinklers be used in a deluge system?

No, sprinklers in a deluge system are "open"; no valve in the sprinkler, and an automatic valve turns on the water to all open sprinklers when a fire condition is detected.


Why are overhead sprinklers inefficient?

Overhead sprinklers are often inefficient due to their tendency to distribute water unevenly, leading to both overwatering in some areas and under-watering in others. Additionally, factors like wind can cause water to drift away from the intended target, resulting in wastage. They also tend to create evaporation losses, especially during hot weather, further reducing their effectiveness in delivering water to plants.
