One of my neighbors has his downspout disconnected from the main plumbing line to divert rainwater from the main drainage pipe and into the concrete space between our twin houses. Instead of getting a plumber to clear the blockage in the main drain he apparently years ago just cut the pipe, put in an elbow, and has the water flowing over the ground.
I approached the neighbor last Summer with my concerns and with recommendations of a good plumber (when I had plumbing and concrete work done) and he was pleasant, but it doesn't seem like the homeowner is going to have any work done. I welcome your feedback as to how I should try to address the situation. The neighbor is a long-time home-owner, has the means to get the work done, but for some reason doesn't think it's important. I think that his setup is a violation of city code (at least I hope it is). But I'm really concerned about the water drainage. My house is down-slope from his and I'm concerned that the constant seepage over time could undermine the foundation of my house. Any suggestions?
