    Roger, thanks so much for this – it appeared the dat after my mate’s stop was leaking. All I did was tighten the gland nut – it stopped the leak but made the tap difficult to turn. I shall be returning in due course with my PTFE!
    Love your videos and your style – many thanks again.

    Nice clear video. I’ve tried to undo the gland nut on our stopcock, and it’s very tight. No surprises there, but the supply pipe into the house seems to be a plastic pipe. It’s a thick pipe, but I can see it flex a little as I try to turn the nut. If the pipe breaks, it will be fairly catastrophic 🙂 I know this is a difficult question to answer without seeing the thing, but have you ever known a plastic mains pipe to break as a result of trying to turn a stiff gland nut?
