Started work this morning to put a new drain and soakaway in for me garage. The old drain seems to be bust, I think it must have been severed when neebs had an extension built (long before we moved here) and it wasn't reinstated. Had to do the same a couple of years ago on the opposite side of the house, drain was severed when t'other neighbours built a garage .
They built (neebs) on their land and severed your drains and not noticed ?
