    Am I responsible for adding isolation valves to old installs?

    If, for example I change a pair of taps (bath, basin whatever) for a customer is it my responsibility to also fit isolation valves if there were none there before to bring it up to current standards so-to-speak?

    Isolation Valve replacement - tips, advice. warnings??

    Hi, First time poster here and not a plumber at all. I noticed a small leak, more of a weep, on the isolation valve which leads to the cistern.
