Water standpipe for toilet sump tanks

Improvements in or relating to a water standpipe for toilet sump tanks, comprising in combination a hollow cylindrical standpipe body of smaller internal diameter in the upper third of its length and containing three horizontal perforations at an angle of 120.degree. from one another to permit the exit of water to the service tank through respective discharger-silencer devices of hexagonal exterior shape;

• a H-shaped plunger containing a cavity in its lower portion for receiving a seal of rubber or any other appropriate material which remains firm in said cavity because of the latter's inverted frusto-conical shape;
• a hollow valve to permit the passage of water, the nozzle of which valve has a diameter slightly less than that of the rest of its circumference, so that a chamber is formed between said nozzle and the inner surface of the body of the standpipe;
• and a rod operationally connected to said plunger by a bolt, said rod being pivotally joined to the body of the standpipe by means of a conventional bolt.
