We've had a Compliance Officer visit from Scottish Water this week and he has left us with a long list of issues that he would like rectified. Most of them relate to the tiny possibility that water will get sucked up the hosepipe/trough inlet pipe and contaminated water will get into the mains water system. He wants all the taps changed around the yard so that you can't attach a hosepipe to them, a water trough which is currently a metal bath changed to a 'proper' water trough and a none-return valve positioned next to the water meter. Can anyone advise me if a none-return valve is fitted next to the meter which supplies all the water to the farm why all the taps have to be changed as surely the valve next to the meter will stop any dirty water in the extremely unlikely event of the water going in the wrong direction up the hosepipe! Also, why is it the down to the farmer to put the none-return valve in next to the water meter and not Scottish Waters? TIA
