A soil pipe is a pipe that conveys sewage or wastewater reliably, either from the toilet or sink, to a soil drain or sewer. They are relatively easy to spot as they run vertically from the underground drainage system to the top of a property or high-rise block, where they reach the roof.

This can often be the case if the soil pipe is old or you have noticed substantial issues with your property’s plumbing. It’s always best to seek the help of a professional plumber when you notice something wrong with your plumbing, as the piping systems can be complex and expensive to repair or replace.

Before any work is carried out, the professional will ensure they have a good idea of the system they’re working on and may create a diagram to ensure they know how each part interlocks. As the original system is likely to have been built according to building regulations, the professional will try to avoid actively changing too much unless the system is being rehauled.

They will remove the soil pipe from its existing location – the method for carrying this out will depend on the professional you use and what the insurers are happy with. A small amount of excavation work may need to be carried out.

The new ones can be implemented once the old soil pipes are removed.
