My house has an extension built on a drain unfortunately and after the soil pipe was moved the builder just put the new soil pipe into the drain without any thought. Now waste builds up and causes a smell. The pipe is very short too.
What would be the best way to get this pipe running into the water like the original pipe. links and modded pics would be appreciated.
Also any recommendations for a sealed lid and frame as I want to change this. Size at the moment is 750mm x 600mm but it could be smaller i'm pretty sure.
