Hello, hope someone can help with this one.
We need to move our upstairs toilet to another wall in the bathroom to make way for a bath. We won't be able to reach the existing toilet stack as the pipe would need to go round the house and a roof drain pipe and garden room roof would be in the way. I can see two possible solutions but not sure if either are possible.
In either case I want to remove the old stack as only the washing machine would run into it (which I can move) and I can then take the stack out of the garden room. Sink and bath washbasin etc go into hoppers or gullies.
Option 1
It's in a 50's excouncil house and the old loo was downstairs under the bathroom. The old pot sewer pipe is still there so would it be possible to take the soil pipe down through the bathroom floor internally and under the kitchen floor and connect to the old poo pipe. If I did this, could I simply vent the toilet with either an Air Admitance Valve next to the toilet or send a small bore pipe out though the wall to vent outside. All the research I have done suggests I need a proper stack but this seems over the top and unnecessary.
Option 2
Make the rainwater drainpipe from the roof into a toilet stack and convert the gully into a sewer with inspection chamber and send the loo pipe into this with bath, sink and roof guttering also.
Thanks for any advice
