Hi all,
I want to move a toilet in a ground floor flat by about 8 meters from it's original location, and further away from the manhole it drains into.
This will make the new toilet about 10 meters from the manhole.
I checked with Thames Water and seems this manhole might connect to a manhole in the neighbours garden 2 doors down, which then connects to Thames Water sewage at the front of the house.
Thames Water want 100mm clearance around any new pipes, and allowing for a 1:40 fall, means I need to dig a deep trench about 600mm at it's deepest point (below the internal floor finish level) and hope it can connect to the waste pipe system inside the existing manhole at the right level.
Questions are:
1) What are the chances the new soil pipe can connect to the existing manhole?
2) Anyone know what level top of the footings/foundations in early victorian houses generally is? I.e. What are the chances the new soil pipe avoids the existing footings/foundations - or go through them?
3) As it's a 10 meter run, do I need rodding points under the floorboards?
4) What do you think the cost of doing this is?
5) Any key questions I'm missing?
Look forward to your help!
