I have dug my drive up and am trying to work out where the rain water runs? The foul waste all runs to my man hole but I cannot find where the rain water runs as the gully traps are blocked and have wet areas. It's a 1930s house. All the drain pipes are clay. Near the man hole I found a length of 1 meter clay pipe that didnt lead anywhere? Someone mentioned it could have been a vent pipe? I take it they didnt use soakaways in 1930?
Thanks
