  • Patent number: 10280606
    Abstract: A non-leaking toilet and retrofit base drain outlet extension apparatus for existing toilets that eliminates the use of wax rings is presented. Extension apparatus fluidly connects to existing drain outlet on a toilet to extend drain outlet further into flange thus preventing leaks. A new toilet can be manufactured with extension apparatus already connected to drain outlet or extension apparatus can be connected to an existing toilet. Extension apparatus can be angled for use in offset flange or can be straight for use in straight flange.

  • 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.
