query on routing waste water pipes..
I have a radon membrane with sub floor over it (100mm). I have ran all the main sewer pipes under the subfloor and they come up from the ground wherever I plan to put a toilet. I have also a few of these in my utility room for waste water. I do not want the waste water pipes from the sinks baths etc etc, to be routed out through the wall and be visable from outside or route out of the first floor to the gables and down. All the sewer pipes on the 1st floor are routed down the interior of the house and out under the subfloor also.
Now my question is as follows. The plan is to run all the 50 mm pipes into the larger 100mm pipes which are up out of the ground (vertical) connect the 50mm pipes into these and then cover over with a 75 mm screed. Prior to the screed I will put down a 50mm kingspan insulation, and will have to cut it around the 50 mm pipes. Or can I cut into the subfloor and sink these pipes into it.???
I am also putting UFH pipes over all of this.
Is it common practice to connect 50mm waste water pipes into the 100 mm sewer pipes, and then screed over.
The other query is that I need to vent the system somewhere. Is this normally vented at the highest point of the sewer system.
I want to install the vent stack through the inside of the house also, through a mushroom slate on the roof, as again I do not want pipes on the exterior of the house. Any ideas how to do this??.
Your experience or input would be much appreciated.
