Automatic Top-Up Tap For Pools

Abstract

A pool top-up tap comprises a conduit from a rain water supply which tops up the pool and a valve assembly which closes off the conduit when the water in the pool reaches a predetermined level. The conduit may supply rain water to an intermediate pool side reservoir which tops up the pool and has an integrated valve assembly which shuts off the water from the reservoir when the water in the pool reaches a predetermined level.

1 . A pool top-up tap, comprising:
 a conduit from a rain water supply which tops up the pool; and,   a valve assembly which closes off the conduit when the water in the pool reaches a predetermined level.   
   
   
       2 . The tap of  claim 1  in which the conduit supplies rain water to a pool side reservoir which tops up the pool and has an integrated valve assembly which shuts off the water from the reservoir when the water in the pool reaches a predetermined level. 
   
   
       3 . The tap of  claim 1  in which the valve assembly comprises a float attached to an arm pivoted to the conduit and a stopper mounted on the arm which closes off the conduit when the float rises. 
   
   
       4 . The tap of  claim 2  in which the valve assembly comprises a float attached to an arm pivoted on the reservoir which operates a valve to close off the water entering the pool when the water in the pool reaches a predetermined level. 
   
   
       5 . The tap of  claim 1  in which the conduit has a tee section upstream from the valve assembly which allows the flow to be diverted to an overflow.
