Help, i have been flooded out of my house because the flow valve on my Ferroli combie boiler blew the blanking plug out of the valve. Ferroli have replaced the valve and the system is up and running, my problem is that i have now heard through the grape vine that this is not a one off. Has any one had the same experiance and is it a design problem, it could happen again and i am concidering replaceing my boiler for an other make.
