I've sheared the top off it. It's a single hole with 2 copper pipes going into it. On the copper pipes are those slotted on/off valves. Now if I turn them off and undo the nuts holding the copper pipe and pull the tap assembly up out of the hole, will I be able to use the copper pipe again or will I need new pipe. Also, do I just wrap gas tape/PTFE tape round the thread? I'm thinking TolishAPurd may be able to help.
