Abstract
A joint device for drain pipes comprises a structural tube made of a rigid material and providing structural integrity to the joint device. The structural tube defines at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for complementary sealing engagement with a pipe of a drain network. An annular seal of resilient sealing material is integrally connected to an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions for sealing engagement with a tailpiece slid downwardly into engagement with the joint device.
Claims20
An assembly comprising:
- a joint device including
- a structural tube made of a rigid material and providing structural integrity to the joint device, the structural tube defining at least part of a drain passage of the joint device, a bottom portion of the structural tube having diametrical dimensions for direct complementary abutment sealing engagement with a pipe of a drain network, and
- an annular seal of resilient sealing material inseparably connected to an inner diameter of an upper portion of the structural tube to define at least an inner surface of a portion of the drain passage of the joint device, the annular seal having inner diametrical dimensions configured for sealing engagement with a tailpiece slid downwardly into engagement with the joint device;
- and
- a drain base having a support portion for being attached to a periphery of a drain hole, a tube portion for receiving and supporting the joint device and blocking the joint device from moving downwardly.
A method for installing a drain assembly, the method comprising:
- sliding a structural tube of a joint device into sealing engagement over a top end portion of a drain pipe aligned with a drain hole in a floor, the joint device being a removable insert within a support tube of a drain base and having a structural tube and an annular seal of resilient sealing material integral to and inseparably joined to a top end portion of the structural tube, whereby the support tube of the drain base is received in the drain hole, and a flange of the drain base rests on the floor around the drain hole;
- securing the flange of the drain base to the floor;
- and
- sliding a tailpiece by downward force through the drain hole into the joint device to form a sealing engagement between the annular seal of the joint device and an outer diameter of the tailpiece.
