Double check valve arrangement
The shut-off valve has a cut-off valve having two parts 108 with an inlet for connection to a water supply 112 and an outlet (122, Fig. 2) releasably connectable to an inlet 104 housing of a float valve 106, the cut-off valve being sealing securable in an aperture in a wall 111 of a cistern 102. The cut-off valve is biased towards a closed, shut-off position and is openable by engagement of the outlet (122) with an inlet 104 of a fill valve assembly. Also claimed is a fill valve assemble 100 for a cistern 102 having an inlet 104 connected to the shut-off valve and a float valve 106 connected to an outlet. The cut-off valve is shown in Fig. 2 and has an isolating member (150) biased by spring (156). When engaged with the inlet 104 of the float valve the member is forced downwards, against the bias, opening the valve. The assembly includes a quick release mechanism 114 having spring biased push button (144) operating sliding locking plate (140, Figs. 2-3b), to maintain engagement of the two parts of the cut-off valve.
