ST 330 Protection of Drinking Water Training Panel
Education / GUNT Hamburg / Thermal Engineering and HVAC / Sanitary Systems /

An open pipe system that simulates a domestic installation for drinking water with four different levels is mounted on the panel of the trainer. The levels represent the cellar (drinking water connection level) and three floors. It is possible to simulate a pipe fracture or a pressure drop. During this process the return of contaminated water into the drinking water pipe can be observed.

Learning Objectives / Experiments

- Function of various safety devices
  * pipe separator
  * backflow preventer
  * pipe vents
- Prevention of the return of contaminated water

  back into the drinking water pipe
