This site has been a great source of information with lots of helpful answers, so here are some more questions.
I am trying to replace a few 1930’s gullies.
This is mostly because they do not allow rodding and I have no access points into the drainage system; one of them is also cracked. 2 out of the 4 Gullies I have investigated so far look easy to do; I am looking for some advice on the other two.
This gully is on our side concrete drive, it is cracked and the escaping water has made a nice dip below the gully and our foundations (only about a foot wide). The top of the pipe going into the present gully is 40cm below the level of the drive.
So will a gully with a raiser cope with the pipe at this level or do I need to cut the pipe back and fit a steeply sloping pipe up to the new gully, if so what angle should I take the pipe down at?
When I reinstate, so I just bed all the pipes in pea gravel and then backfill with something like MOT1 before restoring the concrete – or do I need to do something to stop any load on the new plastic pipe? (I will fill the whole under the foundations in with concrete as well!)
The next problem gully has its joint under the wall of our utility, it also looks like the wall has minimal foundations, but the utility does have a plastic roof like a conservatory. The pipe then runs under the conservatory floor. Is there any reasonable way to replace this gully? If not I will just put the paving back and hope I never need to clear a blockage from there!
Did someone say gullies are easy to fit?
