I recently bought a house and its my first with oil heat. My shower is dripping/leaking hot water. I am calling a plumber to fix the leak as I have no experience whatsoever in plumbing. Meanwhile I don't want to waste my oil by creating hot water that is just dripping out of the unused shower. There is an emergency oil burner shutoff switch at the top of the steps leading to the basement. Should I switch this off to conserve my oil and if I do will it be as easy as switching it back on to get it working again? Thanks for any help you all can give me here. It is my first post.
