Thinking about getting a downstairs toilet put in and a possible route for the soil pipe. The downstairs floor is a suspended timber floor.
The pipe would need to drop straight down from the toilet to below the joists, then about 6m run under the floor, through the outside wall below DPC level and then into the existing stack underground, about 600mm below ground level.
Are there any issues dropping straight down from the toilet with a 90 bend, dropping down about 300mm at a guess then another 90 to run under the floor, or is that normal practice?
How would the connection be made to the soil stack underground, just teed in, and then buried again? The existing stack is cast iron, so I was planning to get that replaced at the same time as getting the soil pipe connected in.
