We have a number of toilets with the new dual flushing mechanisms. I think they are Jollyfill.
Occasionally the flushing mechanism jams open at the bottom, so that water is continuously flushing the toilet. The cistern never fills so the inlet valve does not close off.
Are there simple adjustments that can be made to fix this.Knowing our builder they were probably very cheap (I have had to replace the inlet mechanism on one of them. If the advice is to replace them, how easy is the task - I do not fancy disassembling the cistern from the toilet bowl.
Any advice/help would be much appreciated.
