On departing front door of building noticed drip from celling. Uh oh! Leak from kitchen above communal hallway. Uh Oh ! That is my Kitchen!
So far have learnt that kitchen installers use novel methods of wedging my dishwasher in. Including two saw cuts into metal work and some reshaping with a hammer to avoid an intruding bit of pipework at rear. Oh and they didn't know how to use the rear leveller so had just rested it on a plank and for some reason left a couple of tiles stuck to back of machine as well. Anyway leak is in the drain hose and fitting replacement look like it will be a bit of a pig. Joy.
