I’ve recently moved in. There is a pipe (around an inch wide) in my garden coming from the neighbours wall. Water sometimes comes out it. There’s a homemade contraption that directs the water down the hole in the ground that the down pipe goes down - this is about maybe 2/3 feet away. Which sort of connecting pipe could I use to replace the pile of bricks and bit of metal that currently directs the water? I’ve struggled to find one online.
