    Replace with MDPE , Confirm steel with magnet. Lead will scratch easily. If lead, use lead lock as coupling. If steel, best to find threaded coupling but take care when uncoupling not to unscrew any part of pipework you wish to retain.

    If you can find a joint remove and use a male or female iron or cut pipe and use a philmac trans coupling
