Hi
I hope this is the right section for asking a drainage question
Recently i have had a new building put up, it is a car workshop, i would like a second opinion before i raise my doubts with the contractors, i dont like to complain but if it is wrong i will raise the points with them.
Our waste from the toilets is getting stuck in the first section of drainage
drain A to drain B.
My step son who does building work has been out and measured the depths with a dumpy level at all the drains.
From the measurements we took it would seem there is not enough run on the first section dain A to drain B, and more than enough of a run, from drain B to drain C AND C to D.
I have attached a drawing it is not to scale but the measurements and drops from drain to drain are correct.
I suppose i want to know is could more of run been achieved drain A to B if the run was less between point B to D as the run's dont seem consistent, and the run drain A to B if it were minuim 1 in 10 drop 58mm would only span a distance of 5.8 meters and the distance is 7.9, am i right as i really dont know that much about this kind of thing
