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
* Safety and hygiene of drinking water pipes1 * Drinking water installation for a three-floor house with cellar1 * Investigations on the return of contaminated water back into the drinking water pipe
 Simulation of 3 floors and a cellar of a house  Devices to prevent the return of contaminated water into the drinking water pipe  Possible simulations: pipe fracture, pressure drop  Pipe system made of transparent material  2 risers with vent  6 outlet valves with hose connections  3 transparent water tanks  Pipe separator, backflow preventer and riser vent as safety devices  Water meter in feed pipe
