Hi I have a valiant boiler with separate storage tank upstairs. Every few days the boiler spills out about a pint of water and then pressure drops so I have to top up water in the system and place a bucket underneath the boiler.
I als0 bleed the very top rad as full of air, but not always. Any help much appreciated as over weekend whilst we were away the system went to BMU error but as soon as I topped up the water it was fine???
