Hi All, Had my old cast iron downpipe (house is from 1890's) from the room guttering replaced with PVC earlier this year. Neighbour just informed me that when it rains water is cascading down the walls (its a shared exterior wall, of which I have no view). Its raining today and the pipe is clearly not draining as water is leaking about half way up and running down the outside of the downpipe. Walls starting to go mossy etc. The guys who installed the downpipe just buried it in the soil down to a depth of a six inches or so. I suspect that the ground is not allowing the water to drain so its backing up in the pipe. How can I fix this? Thought of digging it out, putting on a shoe angled away from the house, digging down a foot or so and filling with gravel to aid drainage??? Any thoughts welcome, thanks!
