Hi i have ive taken apart my cistern to replace the syphon, prior to doing this i purchased a Fluidmaster syphon 1 1/2- 2" complete with inlet valve i thought this would do fine anyway ive taken it all apart only to find the hole at the bottom is 2 1/2" i cant find one anywhere or a reducer washer has anyone got any ideas on this.
