  • Patent number: 8955172
    Abstract: An improved method of installing a closet flange allows installation of plumbing fixtures with a reduced likelihood of leaks. The method involves telescopically fitting an inner or outer surface of a drainpipe to a surface of a cylindrical portion of a hub of a closet flange, where the hub has a base flange extending therefrom; and securing the base flange against the upper surface of a subfloor. A first layer of sealant is applied to an upper surface of the base flange; and a flooring membrane is secured to the upper surface of the base flange by the first layer of sealant. A second layer of sealant is applied to an upper surface of the flooring membrane; and the upper surface of the flooring membrane is clamped between the base flange and a clamping ring. The method may be performed using a two-part closet flange for connection to a drain pipe for a toilet.

  • Patent number: 8607368
    Abstract: This is a type of connection device between a toilet and a drainpipe, including a trap with an inlet connected to a toilet flush port and an outlet connected to the drainpipe. The trap has a bend part and a horizontal lower pipe connected to it. Upper and lower inner pipe walls of the horizontal lower pipe have different declination angles. There is a containing part in the inlet; and in the containing part there is a sealing part forming a sealing structure between the flush port and the inlet. This simplifies the complex structure of existing toilet drainage parts for on-site installation and for reliable use. The separated trap design includes structure that can generate a siphon phenomenon. At the time of sale, wash-down drainage can be easily transformed to siphon wash-down drainage just by changing parts, such as the trap of the toilet, thus improving the drainage effect.
