PISCINA DRAIN PIPE SYSTEM ABSTRACT OF THE DISCLOSURE A piscina drain pipe system is disclosed having a tailpiece disposed in a casing within a piscina and controlled by a float-controlled valve stopper assembly for carrying away dirts and the water from the piscina through a drain pipe. The valve stopper assembly opens the top opening of the tailpiece as the water of the piscina reaches a predetermined high-water level, or closes it as the water drops below a predetermined low-water level. The effect of water pressure difference casues dirts to be carried with the water into the casing through bottom through holes thereof as the water drops below the low-water level, so that the dirts are further carried away from the piscina as the water reaches the high-water level again.
