    WRAS water supply to allotments. As far as my knowledge goes and it is not extensive, ALL outside water tops MUST have backflow valves fitted to stop virus or is it viri getting back up the pipe and into the water supply. As we have been told each tap must have two fitted , one at the front one at the rear of each tap. Many on our sites have said why not just have a non return valve at the stop cock, but no it has to be two valves at every tap. What light can any of you shine on this subject, what are your sites doing about this and how is it being implemented. We have already spent a couple of thousand on this and with many failures that is set to rise considerably.

    Please could you let us know if your reply to this is an official comment or just opinion. Many thanks.

    Hi,

    Am not up to speed on current regulations, but thought each outside tap had to have a double check valve fitted either as part of the tap itself on in the pipe just before the tap.

    Think the best people to ask for the advice in your area is your local water company as they may have special rules and regulations for such allotments.

      The regs require double check valves at each tap point. The biggest risk on an allotment would be backflow from a hose left connected to a tap and the tap still left switched on. Contaminated water could then reach other taps which may not be a problem if everyone is just watering their plants, but will be a risk if someone uses it as drinking water or you have an onsite toilet/washbasin.
