Our worchester boiler over the last couple of days has no pressure we had been able to put pressure into the boiler but then it goes down to zero again, we're checked everywhere and they are no leaks etc. Please could someone help as we've got no heating and no hot water. Thanks
look outside at the presure releief valve overflow pipe - if it's dribbling you have to replace the valve or, if you are carefull, clean the crud out - good luck
