During the lifespan of your loo it will definitely fail on at least one occasion. It is also never at the right time is it lets face it. If this should happen, then, the first action to take is to look at the WC closely just to see if there is anything really obvious. That will probably not be the case so you should remove the cistern lid and look inside. Charlton Plumbers can replace diaphragm washers. Should it look ok with the handle mechanism and its parts look to be in order, then, it is likely to be due to a failure of something closer to the water outlet. There is a thing called a diaphragm washer that is probably to blame.Next: Isolate the water supply to the cistern and empty it by using a small bowl and some old rags or cloths. Draw out every remaining drop of water. The siphon should be lifted from the body of the cistern (if you have any doubts take a photo as you take it apart). You will need unhook the linkage to the lever arm, if the arm of the float operated valve gets in the way, you may need to remove this also. Now having removed the siphon you should now be able to see beneath the base and place where the old perished diaphragm washer sits. A Charlton Plumber can do any plumbing job. Remove the hook on the shaft that pulls the diaphragm, this will allow the diaphragm housing to drop from the siphon base. Fit the new washer, re-fit the parts in a reverse order. Switch the water supply back on and check for leaks. Every jointing washer needs to be in a good condition, if not, wrap some PTFE tape around the joining parts.
