Moving Soil Pipe

[Hadventurous]

I am having a new bathroom installed, having had my new boiler moved from the bathroom I have some new found space.

To make most efficient usage of the space I need to move my toilet to another external wall - around the corner from my existing external soil pipe (see photo). I cannot run the soil pipe inside and box it in as the wall that it would pass through to the waste is laced with the pipes to the new boiler (from its old location). The run toilet to stack would be about the same length (plus a angle around the corner).

Any suggestions about how I could run the waste and how I would get past the drain pipe?

I was thinking:

• Sit the waste pipe out from the wall until it goes around the corner so it passes in front of drain pipe.
• Divert drain pipe around waste (then replace later to another location perhaps?

Any experienced advice would be appreciated as the bathroom installers that have looked have all said different things.

I have included a photo with a crude yellow drawing of where approximately the new pipe would be.

Thanks

Which way do the joists run; are they in the right direction to run the soil pipe under the floor If you run the soil pipe outside, then you'd need to put an unsightly kink in the rain water down pipe; 45 degrees outwards, then down, then 45 degrees back in again. The soil pipe would need to turn the corner, and then run down at 45 degrees to make sure that solids didn't stick against the wall on the bend.

Or you'd do the job properly, and re route the drains.

If you're planning on staying there long term, I'd do the job properly, and move the drain to suit. Any idea which direction it goes off in? (Lifting manholes should give you an idea if unsure.)

Thanks for that... The drain from the present stack goes off in the wrong direction and the toilet is against the wall so it would immediately have to plunge to go under the floor boards (although I will have a good look at this as an option).

The most cost effective option so far has been sitting the waste pipe 25mm off the wall so that it passes the drain pipe then connecting to the waste around the corner. Unless under the floor boards looks spacious and the boiler pipes that prevent it running through the wall are missing I think thats the plan...

More like 75mm. If the drains both go to the same manhole I'd swap gully for rest bend and rest bend for gully as Hugh says.

Assuming that gulley is connected to the foul drain....

Nah downpipes go into a soak away separately and is very close to the wall. Should get away with it...

Next question is do I paint that fugly pebble dash and commit to painting it every 5-10 years...

Yup, invest in a HVLP spray with a back pack, and it'll be a doddle - okay, sort off.

Girlfriend currently renting a property, they've dropped the stack into a former gulley. Die no rob are on Speed dial with the agent.
