Ferroli Combi Boiler’s out of order expansion tank

Hello Guys,

Someone please guide me concerning a problem, which is my three years old Ferroli combi boiler is facing since last night. The boiler overflows a lot. I am unable to fix this problem. What is the matter? Is something serious?



Hello, when the boiler’s expansion tank drips the water on the way to outside then, you should check the ballcock because, I am suspecting that the ballcock is damaged & needs the seal replacement. However, before this, check the current state of the water like the water is either cold or hot. In case, it is very hot then do take it seriously. You have to call a Ferroli boiler and ask him to replace a ballcock seal.
