    Cold and hot water pipes


    Why must hot and cold water pipes never touch? How can it be ensured that they won't if work is taking place?

    "Hot and cold pipes should be clipped anyway ,this stops them vibrating and .also if the hot pipes are getting to hot and there right next to cold then it also causes alot of condensation which then can cause mould and damp"

    "The main reason it to prevent condensation if your in doubt an installation then get your contractor to provide pictures or chose a different contractor"

    "Because the cold pipe will cool down the hot water before it reaches the sink. Or the hot water can warm up the cold water before it reaches the sink."

    "They can be fitted with double clips to separate them, cold pipe on the bottom, heat rises, , legionnaires disease can occur at certain temp, and its on your drinking water, if work is going on and there touching temporarily its ok, touching pipes can also be noisy"

    "They usually are only a few mm apart as one can buy double clips for 15mm pipes and you can google search image these double clips .They keep the pipes a cm plus apart .
    The main reasoning is Legionnaire,s disease .
    Cold water should stay cold and if warmed up by a hot pipe then this raises the temperature of the water in the pipe .
    One often hears about this problem in hospitals and bigger buildings .
    Seldom heard of in domestic dwellings ."
