The device according to the invention may reduce the total height of the trap along the vertical axis in the direction of gravity while at the same time having a total trap seal height (G1) (G2) and (GN) of at least 50 mm in order to prevent unpleasant smells from travelling back up the pipe and good resistance to the flow of waste water from the pipe (1) towards the tank (2) and ensuring a correct flowrate with an overall height along the vertical axis in the direction of gravity that may even be less than 50 mm. This innovation obeys a very simple mathematical rule: number x height of trap seals = 50 mm. What this means is that we can create one or more traps (fig 1) (fig 2) (fig 3) (fig 4) and (fig 38) comprising independent trap seals (G1) (G2) and (GN) with different heights, namely the total number of these heights of trap seal meeting the standards in force in each country (namely, in the case of the French standard NF : 50 mm). |
