Tub overflow assembly

Abstract

The tub overflow assembly comprising an inlet, and outlet and a fluid flow path. The inlet having a lowest point adapted to admit overflow water. The outlet adapted to be connected to a soil or waste pipe. The fluid flow path between the inlet and the outlet. The fluid flow path defines a minimum fluid flow level, the minimum fluid flow level being higher than the lowest point of the inlet.

What is claimed is: 
     
         1 . A tub overflow assembly, the tub overflow assembly comprising;
 an assembly inlet, the assembly inlet having a lowest point adapted to admit overflow water,   an assembly outlet adapted to be connected to a soil or waste pipe; and   a fluid flow path between the assembly inlet and the assembly outlet, the fluid flow path defining a minimum fluid flow level, the minimum fluid flow level being higher than the lowest point of the assembly inlet.   
     
     
         2 . The tub overflow assembly of  claim 1 , further comprising a housing, the housing defining the fluid flow path. 
     
     
         3 . The tub overflow assembly of  claim 2 , wherein the fluid flow path comprises a first portion in communication with the assembly inlet and a second portion in communication with the assembly outlet. 
     
     
         4 . The tub overflow assembly of  claim 2 , wherein the housing includes a structural element, the structural element defining the fluid flow path minimum fluid flow level. 
     
     
         5 . The tub overflow assembly of  claim 4 , wherein the structural element separates the first fluid flow path portion and the second fluid flow path portion. 
     
     
         6 . The tub overflow assembly of  claim 4 , wherein the structural element defines an edge having a length, wherein the second flow path portion is substantially vertical, and wherein the length of the structural member edge is more than 25% of the perimeter of the outlet assembly. 
     
     
         7 . The tub overflow assembly of  claim 2 , further comprising an inlet shroud, the inlet shroud adapted to be connected to the housing, the housing and the inlet shroud, in use, sandwiching a portion of a tub wall defining a tub opening therebetween. 
     
     
         8 . The tub overflow assembly of  claim 7 , wherein the inlet shroud defines the assembly inlet. 
     
     
         9 . The tub overflow assembly of  claim 8 , wherein the assembly inlet comprises a lowest point, wherein said lowest point is defined by the inlet shroud and wherein said lowest point is vertically displaced from the assembly outlet. 
     
     
         10 . The tub overflow assembly of  claim 7 , further comprising an inlet cover. 
     
     
         11 . The tub overflow assembly of  claim 10 , wherein the inlet cover is locatable within the inlet shroud. 
     
     
         12 . The tub overflow assembly of  claim 11 , wherein the inlet cover defines an inlet cover surface, the inlet cover being locatable such that the inlet cover surface is flush with at least a portion of an inlet shroud surface. 
     
     
         13 . The tub overflow assembly of  claim 12 , wherein where the inlet cover is locatable within the inlet shroud, the inlet cover and the inlet shroud define a gap therebetween to allow water to flow into the assembly inlet. 
     
     
         14 . The tub overflow assembly of  claim 13 , wherein the gap defined by the inlet cover and the inlet shroud extends around the perimeter of the inlet cover. 
     
     
         15 . The tub overflow assembly of  claim 7 , wherein the inlet shroud defines an inlet shroud flange adapted to be located in a tub opening and having a complementary profile to a tub opening profile. 
     
     
         16 . The tub overflow assembly of  claim 15 , wherein the inlet shroud defines a lip adapted to engage an internal tub surface, the lip defining an external perimeter of the inlet shroud, the inlet shroud perimeter having a different geometrical shape to the inlet shroud flange and the tub opening. 
     
     
         17 . The tub overflow assembly of  claim 1 , further comprising a one-way valve. 
     
     
         18 . The tub overflow assembly of  claim 17 , wherein the one-way valve is located adjacent the assembly outlet. 
     
     
         19 . The tub overflow assembly of  claim 17 , wherein the one-way valve is a duck bill valve. 
     
     
         20 . A tub overflow assembly, the tub overflow assembly comprising:
 an inlet having an inlet lowest point, the inlet being adapted to admit overflow water; and   an outlet having an outlet lowest point, the outlet being adapted to be connected to a soil stack, the outlet lowest point being higher than the inlet lowest point.
