Bathtub waste and overflow assembly

Abstract

A bathtub waste and overflow drain assembly comprises a fitting-T with at least two telescoping joints that do not require tightening to stop leaks. Telescoping sections are provided in a T-fitting that allow joint type connections with the drain and overflow assemblies. The drain and overflow fittings need only be roughly placed before or after the tub is set down. The joints allow the installer to pull the fittings below into place through the drain and overflow holes in the tub. The finish covers, gaskets, putty, and drain basket can then be installed from above to complete the job.

1 . A bathtub waste and overflow drain assembly, comprising:
 a waste-T with a horizontal telescoping section and a vertical telescoping section for attachment above a drain pipe for a bathtub;   a drain assembly for insertion into said horizontal telescoping section and providing for a joint attachment that requires no pipe cinching to complete a water-tight seal between cooperating telescoping members; and   an overflow assembly for insertion into said vertical telescoping section and providing for a joint attachment that requires no pipe cinching to complete a water-tight seal between cooperating telescoping members;   wherein, each drain and overflow assembly provides for simple adjustment of its extension and rotation by pressure that can be applied by an installer through respective drain and overflow ports in said bathtub.   
   
   
       2 . The assembly of  claim 1 , further comprising:
 O-ring seals in at least one of the vertical and horizontal telescoping sections providing for a water-tight seal.   
   
   
       3 . The assembly of  claim 1 , further comprising:
 expansion rings in at least one of the vertical and horizontal telescoping sections providing for a water-tight seal.   
   
   
       4 . The assembly of  claim 1 , further comprising:
 an accordion-type bellows coupling in at least one of the vertical and horizontal telescoping sections providing for a water-tight seal.   
   
   
       5 . A bathtub waste and overflow drain assembly method, comprising:
 installing a bathtub waste and overflow drain assembly having:
 a waste-T with a horizontal telescoping section and a vertical telescoping section for attachment above a drain pipe for a bathtub; 
 a drain assembly for insertion into said horizontal telescoping section and providing for a joint attachment that requires no pipe cinching to complete a water-tight seal between cooperating telescoping members; and 
 an overflow assembly for insertion into said vertical telescoping section and providing for a joint attachment that requires no pipe cinching to complete a water-tight seal between cooperating telescoping members; 
 wherein, each drain and overflow assembly provides for simple adjustment of its extension and rotation by pressure that can be applied by an installer through respective drain and overflow ports in said bathtub; 
   roughly setting the twist and extension of said drain and overflow assembles to suit a bathtub being installed;   reaching through drain and overflow ports in said bathtub to manipulate said drain and overflow assembles into position; and   attaching a drain and overflow cover plate from inside the bathtub to their respective drain and overflow assemblies behind the bathtub walls in order to seal and finalize the installation.
