few videos and reading the instructions figured replacing the innards on the old flush system we had/ just broke was within my means but I've hit a roadblock.
Currently having a leak from the inlet. Have got all new parts more or less apart from the pipework into the cistern.
Basically I cannot seem to get the seal to be watertight so with water in the cistern there is a drip.
Add to this when connected to the water in pipe at the yellow 15mm connector there is now water leaking from that joint too it seems.
