We have had loads of docs/report back from solicitors now. One of note is this map of the waste water set up.
Looks like the red poo poo pipe goes through our boundary/garden (81). Looks like it serves 2 houses behind ours, then ours and our to the main stretch.
The man hole covers are one in the parking area, and another on the road outside our garden wall.
Am I silly to find issue with this? Obviously not ideal but I'm guessing it's fairly common and a non issue really.
Any issue with the drains would be the responsibility of the water company anyway I imagine. I guess it just means if there is ever an issue, they would need access etc and can't build above it etc (we have no intention of such work)

Funnily enough, out current neighbours are selling too and have just bought 73! I jokingly told them no curry nights going forward
