    摘要： A waste water disposal system for a building which saves and recycles the grey waste water for lawn and plant irrigation. The system includes interconnected waste water pipes containing two separate passageways, one for reusable grey water and the other for sewer water, and three different types of T-fittings used with the two passageway waste water pipes, each T-fitting designed to interconnect two axially aligned waste water pipes and having an offset opening to one of the waste water passageways in the fitting, one type of T-fitting designed to discharge sewer water into the sewer water passageway in the fitting, the second type designed to discharge grey water into the grey water passageway of the fitting, and the third type designed to vent to the atmosphere both passageways in the fitting. The system also includes a fourth T-fitting designed to divert the reusable grey water flowing in one of the aforesaid two passageway pipes into a storage tank and also to channel the sewer water flowing in the other passageway of the pipe into a public sewer line or septic system.

    摘要： Device in a waste water installation in a building, comprising a connection box (10, 11) with a flow connection (12) having circular cross section, at one end of the connection box, which is connected to a receiving conduit, and at the other end has a flow connection (12) to be connected to a connection conduit from a sanitary device having a large water discharge, e.g. a closet bowl. The connection box includes a bowl-­or trough-shaped lower portion (10), the lowermost location of the flow connections being substantially in alignment with the lowermost location of the lower portion, and a flat upper portion (11). The connection box is widened in relation to the flow connections, the flat upper portion being countersunk in relation to the flow connections and having one or more connections (15) for connecting conduits and/or air hoods, and has a transition from each flow connection to the widened and countersunk portion of the connection box, said transition having reduced and then again enlarged cross-sectional area for initial damming-up of the flow and following speed reduction of the flow at water discharge from the sanitary device, which reduces the negative pressure so that no supply of air at atmospheric pressure from specific air supply means to the water seals connected to the connection box is necessary.

    摘要： L'invention concerne un dispositif de raccordement (1) d'un équipement sanitaire (2) à une canalisation (3), le dispositif (1) comprenant une tubulure (4) en forme de T, présentant :
    - un premier orifice (41) ;
    - un deuxième orifice (42) ;
    - un troisième orifice (43).
    Le dispositif (1) comprend un organe déflecteur (5) comprenant :
    - une partie de butée (51) destinée à être montée dans le premier orifice (41) ou le troisième orifice (43),
    - une paroi déflectrice (52) prolongeant la partie de butée (51) et pénétrant dans la tubulure (4), la paroi déflectrice (52) formant un guide d'écoulement d'eau provenant de l'équipement sanitaire (2) depuis le premier orifice (41) uniquement, vers le troisième orifice (43).
    Selon l'invention l'organe déflecteur (5) présente un jambage (56) faisant saillie de la paroi déflectrice (52) et venant en appui contre une paroi de la tubulure (4).
