My next door neighbour had a plumber round today to break into what he thought was his incoming supply . Very annoying as I was in the shower at the time and thought something had gone wrong with it not realising the cold supply had been cut off for quite some time after I had checked out the electrics. The mains passes up his drive then tees of to mine, the plumber said he thought it was just an old supply that went to an outside toilet so broke into and fitted a stop cock then connected up to my neighbours garage supply pipe leaving me with no water. It took me a while to convince them that it was too much of a coincidence that my water had gone off at the same time as as the were cutting pipes that they had no idea where they were going. After finally reconnecting my supply the pressure is not as good as it was. I guess it could be that the extra stop cock that has now been fitted is causing a restriction. Another thing I'm not happy about is I think they plan to bury this stop cock which may lead to problems later. what are my rights with my mains supply that passes through my neighbours property. Should I ask my neighbour to get the plumber back and replace this stopcock with a straight coupler.
