Moving a WC but no soil pipe at front of house: any advice?

[studiodaz]

I was wondering if anyone has done this one before and if you may have any advice that could help me out. We are in a 3 bedroom semi and want to split the large front bedroom into two rooms so we can have a shower, WC and sink upstairs.

At the moment we have a WC downstairs on the back right hand side of the house (right hand looking from the front of the house). This is also were the soil pipe is. We want the new WC to be upstairs and on the front left side of the house.
We also have an old outside WC that is on the back left hand side of the house but it hasn't got a soil pipe. The waste just goes into the ground.

What is the best way to put in the waste pipes for the new WC?

Thanks
Daz

Non-plumber here, but in the interestes of giving you summat to read until one comes along....

The outside toilet will not be discharging waste into the ground - it must be going to the sewer system. So, it is feasible to have a new soil pipe fitted which will go down into the ground to meet up with that sewer pipe somewhere. It'll mean a new drain chamber and a manhole cover where they join (for later access) and so some disruption to the ground between the new pipe and the drain.

Not ideal, but consider a Saniflo

Not a good idea having 2 soil pipes.

If you want another toilet you need to see how the soil pipe will run to get to your existing stack bearing in mind you need a drop of 1 inch per metre.

You may not be able to run it under the floor as your joists may be going the wrong way.

You could surface mount it but you will have to box in.

Long soil pipe runs are not a good idea and you can only go 6 metres without extra protection i.e AAV. Also long runs have more chance of a blockage too.

New stack with BCO approval likely to be several hundred pounds to get the job done.

Saniflo have poor reputation for blockages too.

Have you considered moving house instead?
