Help ! The overflow pipe that runs from the expansion tank in my loft to outside the house is constantly overflowing (2 bucket fulls a day).
The float has been replaced twice in the expansion tank AND had the emersion water cylinder replaced as my plumber initially thought the coil may be broken in it.
However, the overflow is still dripping constantly even when the heating, hot water and emersion tank are switched off.
I have emptied a bucket full of water out of the expansion tank but within a couple of hours the water level had risen above the overflow outlet and the dripping started again.
Any ideas ? My plumber is flummoxed !
