How far does a perf pipe soakaway have to be from any buildings?
On an aside - the concrete I shoved down the old bog pipe hasn't visibly shrunk and seems to exhibit no movement when I jump up and down on it :)
Now, leading on from that, having blocked 2 redundant entries to a manhole outside, I am left with one - that is blocked upstream but appears to be for a gutter downpipe nearby.
As it is blocked, said gutter downpipe is doing lord knows what underground.
So it's soakaway conversion time if possible...
As I have 1.5-2.5' earth on top of clay, I'm considering running it out via a 110 bottle trap, into solid pipe, then when far enough from everyone's houses, convert into a perforated pipe sitting about a foot-foot/half down on top of the clay.
This firstly depends on gradients permitting. It also depends on clearences required.
If I don't go far enough I will affect the conservatory I have plans for. If I go too far, I get close to teh neighbour's house.
If it all becomes impractical, I will have to connect to the main drain which is 3ft away - but I'd like to move to soakaways all round and get a reduction in my water-waste bill.
