    Hi all,

    I have a new kitchen sink tap to install. The new tap comes with x2 servicing valves and flexible connectors.

    I've attached a picture of how the current tap is connected:


    As you can see it has two copper pipes going into some speedfit type connectors.

    My questions are as follows (no experience with speedfit stuff)

    1) can I just disconnect the copper pipes and attach the servicing valves/flexible connectors to the existing speedfit connection? or do I need a new / another connector (I see speedfit do their own flexible connectors)

    2) Do I need the servicing valves to comply with water regs? they would be useful actually since we don't appear to have an internal stoptap.

    3) Should the piping be earthed here somehow? I gather using plastic connectors means you need to earth again, I assume the sink was plumbed in professionally so not sure why it wouldn't be? I do occasionally get mild shocks around the sink /washing machine/tumble dryer area


    Thanks for any help

    You could put a small piece of copper pipe in the speed-fits and connect isolation valves to that.

    Or, put small length of pipe in isolators and push other end into speed-fits.

    Get an electrician to look at the electrical shock problem ASAP could be lethal.

  5. Your copper pipe would only be earthed if the rest of your house has been earthed. If there is an earth connection to your pipes somewhere under the sink then you need to continue it to the copper tap tails, thus bypassing all the plastic. But if it's not there, there's no need to worry.

    Thanks all,

    one more stupid question - M10 / M12 when referring to connectors; what does this mean? A size I assume, how do I know what size I have for example


    cheers

    No.

    No.

    There are one or more serious faults which could kill someone. Get this investigated and fixed immediately.
