Lying on a pile of stuff awaiting removal in the garden of the neighbour of a friend is a fairly new close coupled toilet. The neighbour was pottering about and I asked her why such a modern push button toilet had been discarded. She told me that it didn't always flush very easily and sometimes kept running. The plumber told her they couldn't be fixed and she needed a new toilet. She now needs the floor tiling fixing as the new toilet has a different "footprint" I guess it is a case of the tradesman not being bothered to look up the manual of the flush mechanism or wanting to get involved so he fitted a new bog from Screwfix.
I am also somewhat bemused by people who leave the choice of major items to the tradesman.
