We have this problem in our block of flats but cant figure out the
problem. its an old victorian conversion with 4 flats. Only the flat on
the first floor has no cold water in the bathroom, theyre having to
fill the toilet from the kitchen sink.
some cold water does flow into the toilet cistern if you turn on the
hot water tap in the bathroom!
About the same time as as this an overflow pipe started dripping (this
is not the toilet overflow).
They do have an old water tank (waiting to be removed) in their kitchen
cupboard, he assures me this has been emptied as they have a combi
boiler in the bedroom for all the heating. The overflow is next to the
waste pipe from their kitchen but its impossible to trace the pipe
leads from under the communal hallway.
Anyone have a clue what these two problems could be?
thanks in advance
Perhaps the empty tank in the kitchen is still connected to the bathroom
The plumber probably thought that the tank was only used for the hot water,
so drained it down and fit the combi onto the mains. However, if the same
tank supplied the cold taps, these would now stop working.
This might happen with a mixer tap in the above situation. The mixer
probably back feeds the hot water up the empty cold supply pipe until it
comes out of the toilet valve.
