Terminology
You will need to understand your:
- water system
- associated equipment, and
- be familiar with its constituent parts, such as:
-
Dead/blind end – a redundant length of pipe, closed at one end, through which water cannot flow. -
Dead leg – a pipe leading to an outlet through which water flows but the outlet is unused/rarely used. -
Sentinel outlets – the nearest and furthest/last outlets from hot and cold water cylinders and tanks.
-
Thermostatic Mixer Valves (TMVs) – these blend hot and cold water to reduce the temperature where a scald risk is present.
