Checking a few things tonight, it appears that most of the useful stop cocks in my house are seized! I recall freeing one of them off before but have left it alone tonight rather than cause a leak!
One (On the rising main) is in a rather inaccessible place to replace the whole thing but I wondered if I could leave the body in place and replace the internals (tap, stuffing box, shaft and valve)? Are these bits fairly standard and interchangeable? Or will it be scale in the body and around the valve and seat that has caused it to seize so no point changing the internals?
