    Broken clay soil pipe collar?

    Hello, we are having some groundworks done and have noticed that where the concrete has been partially removed around the bottom of the soil pipe (from toilet etc), it has exposed a gap at the end of the plastic pipe which is leaking - it looks maybe like the collar on the lower clay pipe has...

    Soil pipe across wall

    Hi, we currently have a vertical soil vent pipe. It is in the way of where we would like to build a rear extension.

    Side Extension - Moving soil pipe

    It's a semi detached house with private man hole and drains. The soil pipe is on the side of the building and a new side extension is being built. A new manhole is also being built to move the drains and then connect to main manhole. But for the soil pipe, I think there won't be enough drop...

    Core drilling near footing

    I want to core drill through the cavity wall, underground, for a soil pipe. Due to the depth and location of the existing outside drains it will be very close to the footing, practically resting on it. It will need to be about a 150 mm opening. Is this a concern for structural stability? DIY-able?

    Joining 110mm vertical soil pipe to cast iron pipe

    I've recently removed an old and cracked soile pipe from the rear of my house, which I had planned to replace with a nice new PVC soil pipe. I pulled down the cast iron pipe leaving a stump at the bottom to join to. However, I hadn't realised when I got the new pipe that the diameters weere...

    Moving my soil pipe and vent?

    I'm planning on moving the toilet in my bathroom along a bit from where it currently sits, but I also need to move my soil pipe vent since it now comes out too close to my new loft velux window. Because of this it I think it makes sense to just move the soil pipe hole to where the new toilet...

    Question: Toilet waste opposite bath/basin

    Hi, I'm new here. We're redoing our bathroom and would like to join toilet waste on one side of a branch, and a conjoined bath and basin on the other side. The regs say this is iffy with a non-swept junction. Would a swept junction like this work if we put a 50mm to 110m offset adapter like...
