Abstract
Drain pipe assemblies are provide that include a first flexible pipe having a first end, a second end, and a plurality of convolutions formed therein. A first female threaded connector is is provided that is configured to receive one of the convolutions of the first flexible pipe therein. In this way, the first female threaded connector can form a seal when the one of the convolutions received therein is proximate the first end of the first flexible pipe and the first female threaded connector is threadably coupled to a first male threaded coupling. A retainer is provided that is configured to dispose a portion of the flexible pipe therethrough to form and retain a trap in the first flexible pipe. Methods of installing and using such drain pipe assemblies are also provided.
Claims20
A drain pipe assembly comprising:
- a first flexible pipe including a first end, a second end, and a plurality of convolutions formed therein, wherein each of the plurality of the convolutions formed in the first flexible pipe is formed from an elastomeric material;
- a first female threaded connector configured to receive one of the convolutions of the first flexible pipe disposed proximate the first end of the first flexible pipe therein with a flange of the first female connector positioned behind the one of the convolutions wherein a first side of the one of the convolutions received in the first female threaded connector is directly engaged by the flange of the first female threaded connector and a second side of the one of the convolutions received in first female threaded connector is directly engaged by a male threaded coupling when the first female threaded connector is threadably coupled to the male threaded coupling with the one of the convolutions received in the first female threaded connector compressed directly between the flange of the first female threaded connector and the male threaded coupling, and wherein a fluid-tight seal is formed where the male threaded coupling directly engages and compresses the elastomeric material forming the one of the convolutions received in the first female threaded connector along the second side thereof to prevent leakage of a fluid from an interior of the first flexible pipe at a junction of the first flexible pipe and the male threaded coupling.
A drain pipe assembly comprising:
- a plurality of flexible pipes, each of the flexible pipes including a plurality of convolutions, each of the plurality of the convolutions of each of the plurality of the flexible pipes formed from an elastomeric material;
- a plurality of female threaded connectors, each of the plurality of the female threaded connectors configured to be threadably coupled to a male threaded coupling, each of the female threaded connectors configured to receive one of the convolutions of one of the flexible pipes therein with a flange of the corresponding female connector positioned behind the corresponding one of the convolutions received therein, wherein each of the convolutions received in one of the female threaded connectors includes a first side directly engaged by the flange of the corresponding female threaded connector and a second side directly engaged by the corresponding male threaded coupling that is threadably coupled to the corresponding female threaded connector with each of the convolutions received in one of the female threaded connectors compressed directly between the corresponding female threaded connector and the corresponding male threaded connector, wherein a fluid-tight seal is formed where the second side of each of the convolutions received in one of the female threaded connectors directly engages the corresponding male threaded coupling to prevent leakage of fluid from an interior of the corresponding flexible pipe at a junction of the corresponding flexible pipe and the corresponding male threaded coupling;
- a multi junction connector including a plurality of junctions, each of the junctions coupled to one of the flexible pipes;
- a retainer configured to dispose a portion of one of the flexible pipes therethrough to form and retain a trap in the one of the flexible pipes.
