Right.. after almost a year we now have a free ish flowing drain.
I installed a manhole, and 2 rodding points and have had dyno-rod in to jet the whole lot out and its now flowing.
What I want to do now is stop it getting blocked up again.
The main culprit is silt im guessing from leaves and the like. but there was also some gravel and a teaspoon in there!
id like to construct some kind of sieve at the upstream end where the pipe enters our property. i think it would be a silt trap.
is there a commercial product that will do the job? or should i dig a simple hole, concrete and brick sides? then perhaps a mesh guard over the outlet pipe?
the only other complication being that the pipe is quite close to the house. so would having a hole be problematic for the foundations?
its under half a meter away.. maybe more like 250mm.
refer to the diagram in the OP. im talking about the bottom left of the image where the pipe goes under the fence.
cheers.
