Waste Outlet

Abstract

A waste outlet for a plumbing fixture comprises a body adapted to be located in the fixture outlet. The body defines a throughbore, and a portion of the throughbore includes a trough surrounding a flow opening.

1 . A waste outlet for a plumbing fixture, the waste outlet comprising a body adapted to be located in the fixture outlet, the body defining a throughbore, and a portion of the throughbore including a trough surrounding a flow opening. 
     
     
         2 . A waste outlet as claimed in  claim 1 , wherein the trough is a circumferential trough. 
     
     
         3 . A waste outlet as claimed in  claim 1 , wherein the flow opening is axially aligned with the throughbore. 
     
     
         4 . A waste outlet as claimed in  claim 1 , wherein the trough is U-shaped. 
     
     
         5 . A waste outlet as claimed in  claim 1 , wherein a wall of the trough defines at least a part of a wall of the opening. 
     
     
         6 . A waste outlet as claimed in  claim 5 , wherein a sidewall of the opening is substantially axially aligned with the main throughbore axis. 
     
     
         7 . A waste outlet as claimed in  claim 1 , wherein the waste outlet is adapted to be connected to a waste pipe. 
     
     
         8 . A waste outlet as claimed in preceding  claim 7 , wherein a sidewall of the flow opening is adapted to be substantially aligned with an internal surface of the waste pipe. 
     
     
         9 . A waste outlet as claimed in  claim 1 , wherein at least one of the trough and opening is defined, at least in part, by a member located in the body. 
     
     
         10 . A waste outlet as claimed in  claim 1 , wherein the body throughbore accommodates an internal strainer. 
     
     
         11 . A waste outlet as claimed in  claim 10 , wherein the strainer is adapted to be removable from the throughbore. 
     
     
         12 . A waste outlet as claimed in  claim 1 , including a cover for location over an inlet to the throughbore, the cover being adapted to permit water to flow into the throughbore. 
     
     
         13 . A waste outlet as claimed in  claim 12 , wherein the cover is adapted to provide a filter. 
     
     
         14 . A waste outlet as claimed in  claim 13 , wherein the cover acts as a coarse filter and a strainer provided below the cover acts as a fine filter. 
     
     
         15 . A waste outlet as claimed in  claim 12 , wherein an edge portion of the cover may be spaced from the body to permit water to flow between the cover and the body. 
     
     
         16 . A waste outlet as claimed in  claim 1 , wherein an element of the body includes a mounting flange extending transverse to the throughbore. 
     
     
         17 . A waste outlet as claimed in  claim 16 , wherein the waste outlet is securable to a shower outlet by sandwiching a portion of the shower base between the underside of the mounting flange and another element of the outlet for location below the base. 
     
     
         18 . A waste outlet as claimed in  claim 17 , wherein the body elements define corresponding screw threads. 
     
     
         19 . A waste outlet as claimed in  claim 1 , further including a non-return valve. 
     
     
         20 . A waste outlet as claimed in  claim 1 , wherein the body defines a water-receiving volume extending transversely of the throughbore. 
     
     
         21 . A waste outlet for a plumbing fixture for directing waste water from the plumbing fixture to a waste pipe, the waste outlet comprising:
 a body adapted to be located in the fixture outlet, the body defining a bore through which waste water flows in use and having a wall portion configured to direct at least part of the flow of waste water radially inwardly to eliminate an air core in the waste water flow.   
     
     
         22 . A waste fitting for a shower outlet, the waste fitting comprising:
 a body adapted to be secured in the shower outlet, the body defining a throughbore; and   a filter releasably mounted within the throughbore.   
     
     
         23 . A waste fitting as claimed in  claim 22 , wherein the filter comprises a grid. 
     
     
         24 . A waste fitting as claimed in  claim 23 , wherein the filter comprises an annular body surrounding and supporting a filter member. 
     
     
         25 . A waste fitting as claimed in  claim 22 , wherein the filter is removable via a body inlet. 
     
     
         26 . A waste fitting as claimed in  claim 22 , wherein the filter is located below a removable cover. 
     
     
         27 . A waste fitting as claimed in  claim 26 , wherein the cover serves as a coarse filter and serves to conceal the filter, such that material caught by the filter is not normally visible to a user. 
     
     
         28 . A waste fitting as claimed in  claim 26 , wherein an edge portion of the cover may be spaced from the body to permit water to flow between the cover and the body.
