Hi - first of all i should point out i'm a plumbing novice!
I need to change the temp sensor in my Ferroli Sigma 60-100. It's a wet sensor so i'm informed i need to isolate and drain the boiler first - can anyone tell me how to do this or should i call in the experts?
It's a gravity fed system (non-sealed).
Also how do i then refill / restart the boiler - any particular steps to take?
Any help / advice would be much appreciated - thanks!
