We’re thinking of having the door to our extension in the blue shaded area - which passes through the existing SVP. How easy is it to rotate the exit pipes for the two toilets to go the other direction to join to a relocated SVP (proposed pipes shown in red). Could this work all be done...

Hello, hoping I can get some feedback on a drainage layout I'm trying to do for our extension. This is an update on an earlier design I posted - I've now removed the internal manhole and it is located outside instead :) We have a private combined drainage system that heads over to our...

Hi, I'm trying to self plan a rear extension to our semi-detached house, and hoping someone could give some feedback on my drainage plan. Currently the rain water pipe (RWP), and soil vent pipe (SVP) connect to a manhole at the rear of the property. This is a private drain, that then runs into...

Hi, we currently have a vertical soil vent pipe. It is in the way of where we would like to build a rear extension. I’m hoping someone could offer some guidance here as without moving this pipe we’d be unable to open up the rear of the house. Is it likely to be acceptable to remove the bottom...

Hi All, We are going through a cellar to basement project and just want to ask a few details about the drainage layout and what offers both building regulation coverage, but also what is the most practical solution. We aren't 100% tied to the layout so if a more suitable layout would be...

We have recently bought a new house with a bathroom at the front (no toilet) and a WC at the rear. Waste and SVP are located at the rear of property where is current toilet is. How hard and expensive will it be to relocate or even install a new toilet to the bathroom at the front of the...

hi there. I've just purchased a house. It has an internal soil stack which passes vertically through the house and emerges through the flat roof whereupon it vents. Currently, the bathroom is on the top floor and the waste connects directly into that soil stack (which is boxed in). I want...
