If so how?** A: if you are replacing a Siamp Dual Flush Cistern Valve Siphon with the same model its easy. It comes apart near the bottom and you can replace the top part whilst keeping the old connector in the bottom of the cistern (see Siamp online how to video ). If the existing valve is a different make then its best to replace everything. the cistern may have to be taken off the wall but only if you have limited access to the underside. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A top product, without disturbing the cistern or any ... *by A***R on 22 September 2014* A top product, without disturbing the cistern or any other pipe work the flush valve can be changed when it wears thanks to a bayonet system. ### ⭐⭐⭐⭐⭐ Five Stars *by M***N on 12 December 2017* first class ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on 29 June 2015* Did the job and saved on plumbers fee.
