Hi there,
In the process of renovating the back garden which involves lifting the old driveway (runs the length of the side of the house) and re-laying it with new slabs. In doing so, I’ve come across a bit of an issue with the rear drainage. This grid takes a mixture of gutter rainwater, kitchen waste water and upstairs WC bath/sink waste water.
As you can see from the first picture, the circular aperture on the underside of the grid has been grossly misaligned with the circular drain in the ground. It’s off by at least an inch and a half. More worrying is the fact that it’s completely open – the grid is sort of suspended by the concrete and house bricks above the drainage system – so all the waste water spills over into the surrounding clay and, presumably, the brickwork and foundations of the house.
The gulley that you can see (in the third picture) with pooled water in it is due to the fact that I removed a piece of drainpipe that had been buried, with one end stuck between the grid and drain, and the other end supposedly providing a run-off for the patio area (it was useless as the pipe was full of clay). Total bodge. Occasionally, if the drain ever gets blocked, the kitchen begins to smell.
How do I correct this? My thought was that I’d replace the grid that collects the assorted waste water and make sure that it actually funnels the water into the drain. I assume there is a metric-to-imperial connector that would do this? I’d probably need to excavate the surrounding concrete to align it properly, before re-filling the gulley with concrete to secure it in place?
Any advice would be appreciated.
