Hi,
We have a large semi about 100 years old, one of the drainpipes from the roof gutter is at the boundary of the two houses and takes water from the roof valleys of both properties.
I have noticed a small damp patch on the wall behind where the drain pipe runs and decided to investigate. The down pipe is plastic and undamaged but I found that the gully that the pipe runs into was completely blocked with soil and stones etc.
Dug as much out as I could get to and am now left with standing water in the gully which is still very slow to drain.
I tried to find where the drain ends up and it appears that the pipe runs under the garden at the boundary (under a 6ft hedge) and appears as an open 100mm pipe in the garden wall which then runs across the pavement via an open channel and hence into the road gutter.
I have tried filling the gully with water and as I said it drains out slowly but no water appears at the open pipe by the roadside, could it be designed this way as some sort of soakaway with the pipe there to handle excess water when required?
If not, then does this look like a blockage in the pipe run under the hedge and if so, what is the best way to clear it (rods?).
Also, is it still possible to get 8inch gully grates (round) no one seems to stock them locally.
Thanks
