hi peolple my baxi duo-tec recently lost pressure and i couldnt get hot water so i added water using filling loop till up to recommended level and i must put bit too much as it went into red next day when heating on and water was dripping from the caseing but soon stopped after turning heating off and bleeding a rad to lower pressure, few months past and same happend but this time i the only way i can stop it was to turn heating temp down on boiler and not done it since, been told its a valve that lets air out if pressure to high but may of took water onboard,
any ideas and what should do??????
