I wish to lower some paving round my house, as it is too close to the DPC (damp-proof course). However the drain pipe will not be very far under the new level of the new paving. Therefore how can I fit a drain gully when the outlet pipe is only a few inches below the top of the gully?
(All the gullies I have seen has the pipe outlet near their bottoms, rather than near their tops.)
This is what I mean by a drain gully.
The is the problem.
The problem I have is that the current level of the drain pipe (in the ground) is about the same as the level I need the top of the Gully hopper to be.
