Relocating toilet

[leedjc]

Morning guys

I'm just pulling out our old downstairs bathroom and digging out a channel to extend the soil pipe so we can relocate the toilet.

Seems like a straightforward job... however, I didn't realise that the soil pipe enters the building under the dpm.

My plan was to dig down to the soil pipe level remove the existing 90 deg bend, and attach a coupling to the straight section of soil pipe.

However, while digging down the first section of channel, I've hit the dpm.

From what I can see I have two options. Cut the pipe back after the 90deg, and add another effectively creating an S bend with the two angles, and run the pipe on top of the dpm. I'm not 100% convinced that's the right way to do it...I think getting the correct fall will be tricky.

Alternatively, I dig through the dpm and try to repair afterward. What are your thoughts on this? How easy is it to repair a channel cut through the dpm? It'll be approx 3m long in total

Thanks!

Cut through your dpm and repair it once you've finished. You can use a liquid dpm if it makes it easier to make the repair.

Thanks, that seemed like the best option to me as well
