The rear corner of my guttering overflows, sent my lad up but he can't get it any higher, the downpipe is the other side and between next doors, my lad said it was dry at the downpipe but the rear guttering was nearly full, so I think the downpipe needs lowering, problem is it's hard to get to and would need us to go on next doors car port, but that is old and would probably break.
Now what I'm thinking is at the rear where it leaks there is the big pipe that goes from the toilet and up past the guttering, (I'm thinking this is for ventilation?), could I put a join in the guttering and this pipe so the rain water goes down that pipe?
