I notice that our front drain pipe, overflows all over the front of the granite and is culturing quiet a garden of moss etc. Now it over flows, because the pipe that is soposed to lead it under the pavement is blocked. its blocked due to road re-serfaceing, the road is now at least 4" higher than it ought to be. Now looking at all other houses in the street, they have had the same problem and almost universally have chopped the pipe off and put a "turn out" on it, discharging over the pavement. i might do the same (probably will).... but im wondering if the council will object. And is it just a question of angle grinder it off and push on a fitting?.... (its a narrow 3"? and appears to be cast iron.
