Great replacement dual flush valve
I purchased this to replace an old model as the toilet kept flushing. It was easy to twist the old flush valve out and replace with new. Now no flushing issues and works well. Only point i would make is that the cord is slightly shorter that the old one. In addition, I had to use a hack saw to reduce the height of the overflow due to the size of my cistern. I have attached a photo of the old version to help.

Good replacement
Easy to fit in a very confined space. A lot cheaper than calling out the plumber. Website provides fitting videos which helped a lot.

Siamp 32500007 Optima 50 Flushing Mechanism
An excellent product that seals the cistern outlet completely and the flushing mechanism works perfectly. A very good purchase which I installed as a direct replacement of the original.

Great item for a direct replacement
Great item for a direct replacement. No need to keep the carrier (bottom section) as if you have a previous one fitted, just quarter turn to inlock the top section and swap over with the new section. No instructions so was a little confused as the water level was lower than the central overflow tube but you have to cut the centre tube with a fine tooth saw/hacksaw when you have determined the correct overflow height. The graduation son the side of the central tube give you a guide. Easy fit, ten mins plus sawing time. Reconnect up the push button and all good.

Great value swap. Reusing old close couple kit as it just unscrews.
Seems great, 5 minute swap for dodgy old one. Comes with long collar for low bogs.
