I have a hole (caused by corrosion) half up the expansion tank. Has been there for months and water has never leaked out because the water level is below the hole. Until this morning that is when I noticed water dripping out......

I done a temporary fix but I wanted to know why the water level in the expansion tank has all of a sudden risen. Could it be because of the cold weather we are having and therefore the heating been on more than usual?

Maybe your ballcock froze open overnight?
