Siamp Optima 49 Dual Flush Valve is suitable for a variety of toilet cisterns due to it's adjustable height design. It features a 2 part design which allows easy servicing without having to remove the cistern. The overflow can be cut increments of 4mm, and its flush is adjustable. It also comes with a foam pan seal that compensates for any pan irregularity. The stirrup fixes the cistern lid, once the button is screwed down and enables a non-alignment position.
