also, any good spanner (size etc) to access and undo the nut as it's at the back a bit!... or will a normal wrench do? cheers for your help I really appreciate it all.
Hello everybody I have a boiler question I'd love help with if possible?
My pressure relief valve is dripping, constantly, and I need to replace it.
My concern is if I shut off the boiler isdolation valves, when I re open them I will get a leak which will be bad!
Is there any good way...
