Shower Drainage

Abstract

A pump for use with a shower base includes a pump chamber ( 12 ) having an inlet for receiving water from a shower base and an outlet ( 14 ) through which the water is pumped; such that the inlet can be connected to the shower base such that the water drains directly into the pump chamber ( 12 ) from the shower base. A wet floor former ( 55 ) for supporting a water resistant floor covering material, comprises a base having a predetermined fall, and a trap towards which the fall is directed, the trap comprising a sump which is provided on the base, a shower water inlet through which water from the floor covering material can enter the sump, and a waste water outlet, the sump acting as the pump chamber ( 12 ) when a pump is installed.

1 . A pump for use with a shower base, comprising a pump chamber having an inlet for receiving water from the shower base and an outlet through which the water is pumped; characterised in that the inlet can be connected to the shower base such that the water drains directly into the pump chamber from the shower base.  
   
   
       2 . A pump as claimed in  claim 1 , further comprising a filter cover mounted over the pump inlet.  
   
   
       3 . A pump as claimed in  claim 2 , further comprising a motor mounted above the pump chamber and below the filter cover.  
   
   
       4 . A pump as claimed in  claim 3 , wherein the motor is located above the level of the shower base.  
   
   
       5 . A pump as claimed in  claim 4 , wherein the motor drives an impeller positioned in the pump chamber by means of a drive shaft which passes thorough a waste opening in the shower base through which water also drains into the pump chamber.  
   
   
       6 . A pump as claimed in  claim 1 , further comprising a motor mounted below the pump chamber.  
   
   
       7 . A pump as claimed in  claim 1 , further comprising sensors for detecting the presence of water in the pump, output from the sensors being used to operate the pump.  
   
   
       8 . A pump as claimed in  claim 1 , comprising a non-return valve in the pump chamber.  
   
   
       9 . A shower base unit having a drain opening and comprising the pump of  claim 1  connected directly to the drain opening.  
   
   
       10 . A shower base unit as claimed in  claim 9 , wherein a filter cover is mounted over the drain opening, the pump being located below the drain cover.  
   
   
       11 . A shower base unit as claimed in  claim 9 , comprising a tray.  
   
   
       12 . A shower base unit as claimed in  claim 11 , wherein the pump chamber is formed integrally with the tray.  
   
   
       13 . A shower base unit as claimed in  claim 9  comprising a former having an upper waterproof layer which is clamped around the pump inlet.  
   
   
       14 . A wet floor former for supporting a water resistant floor covering material, the former comprising a base having a predetermined fall, and a trap towards which the fall is directed, the trap comprising a sump which is provided on the base, a shower water inlet through which water from the floor covering material can enter the sump, and a waste water outlet, the sump being configured as a pump chamber for receiving a pump mechanism for pumping water from the sump through the waste water outlet.  
   
   
       15 . A wet floor former as claimed in  claim 14 , wherein the sump is formed integrally with the base.  
   
   
       16 . A wet floor former as claimed in  claim 14 , further comprising a clamp surrounding the shower water inlet and by which the floor covering material can be clamped to the base.  
   
   
       17 . A wet floor former as claimed in  claim 16 , wherein the clamp attaches directly to the sump.  
   
   
       18 . A shower base comprising a wet floor former as claimed in any of claims  claim 14  and including a waterproof covering secured to the base.  
   
   
       19 . A shower base as claimed in  claim 18 , further comprising a pump mechanism mounted in the sump.  
   
   
       20 . A shower base comprising a wet floor former for supporting a water resistant floor covering material, the former comprising a base having a predetermined fall, and a trap towards which the fall is directed, the trap comprising a sump which is provided on the base, a shower water inlet through which water from the floor covering material can enter the sump, and a waste water outlet, the sump being configured as a pump chamber for receiving a pump mechanism for pumping water from the sump through the waste water outlet, wherein said shower base includes a covering secured to the base and the pump mechanism is mounted in the sump as claimed in  claim 19 , wherein the pump mechanism is a pump as claimed in  claim 1.
