Our kitchen hot tap would not work - it looked like the geyser was blocked - or the pipes.
The only way to access the geyser is to go up into the roof - an operation that requires us to bring in a long ladder - get out torches and climb around inside the roof.
My husband went up in the roof dreading what he might find.
When he investigated he found that the tap feeding water to the geyser had been firmly turned off!
No one had been in the roof and it would be impossible to turn off the tap without accessing it this way.
So who was responsible?
