Would welcome any advice on this - probably nothing, but anxious to understand if it's normal or not.
We have a corner bath - not huge, but possibly bigger than a straight tub. We can just about fill it with a mix of hot and cold water before the tap just dries up, i.e. the water stops coming. I can understand that the hot water might be all used, but would have thought that, having turned off the hot and trying to "top up" with cold, the system should be able to, I dunno, draw from the mains water supply even if the tank in the attic is empty... making any sense?
I know almost nothing about plumbing but I can say that we have one of those systems with an expansion vessel, I think they're called - red globe beside the OFCH boiler in the kitchen. Only one tank in the attic.
Thanks in advance for any wisdom/opinions.
