hi, i do hope you can solve this for me we have a potterton 80 combi boiler,its 10 years old now.
when you turn a tap on to high,then turn it off you can hear the boiler still running, the pressure seems to build up , then the boiler makes a real heavy noise,bangs,clunks then cuts out,it sounds like there is air trapped.
if you only turn a tap on half way its fine,same as the shower turn it full on then off the same happens ,it a gainsbough power shower.
i then have to keep pressing the reset button,everytime this happens,as the boiler cuts out,unless you reset it theres no hot water.
it only used to happen maybe once aweek,now its everytime i use the tap,
just recently my husband changed the pipework from the boiler running upstairs to the bathroom because it was an old lead pipe,which we came across through gutting our kitchen,
it seems to be a build up of pressure,the funny thing is i can hear the boiler building up sometimes so i rush to the tap turn it on the water then pours out with such a pressure behind it and dangerously hot,then its cold where its cut out,then i reset it again.
it seems so odd,we have blead the rads,which we do quite often, the bathroom one holds air sometimes,each one has its own thermostat.
please advise
thanks
