I have a tub faucet, and it is supposed to thread onto my copper pipe that juts out of the wall, however my pipe hasn't got a thread on it, to screw the faucet on! My mum told me there is a tool you can get that makes a thread in your copper pipe, do any of you know if I would be able to get this tool at Home Depot? or a plumbing store in the Oshawa Ontario region? Help! it's extremely important that I find a tool like this.
