I ve been to see a customer today who has a well supply private water supply. It's pumped from a field about 250 yds from the house. The 25mm blue mdpe pipe is literally run along the top of a boundary fence, through the woods, and down the hill to the house. Obviously it freezes during the winter. The people have just bought the house and said the previous owner just used bottled water for a bit in the winter!! They re not up for that! I ve never come across this before so my two questions are, what can I do to replace if with something less likely to freeze and where do they go for a water test? From what I ve read the local council should be a blue to help with that. And also what is necessary in terms of filters etc for the supply to comply with current regs? Thanks for your help.
