Moving a Gully for extension

[Andy Vickers]

Hello. I posted this in Plumbing but it's a general building Q too. So hopefully some of you wise bods can chip in. Is the Soil pipe allowed to stay in place if the extension ends up been an open plan kitchen diner by boxing it in.

Cant see any of the pics, so it's difficult to ascertain what you're hoping to do.

Thanks. I'll repost on my pc. Looked fine on my phone

Hello,
Ive a bit of a conundrum regarding my existing gully trap that is located next to my current kitchen extension.
The plan is to extend sideways to make the narrow galley kitchen in to a kitchen diner by removing existing windows and door subject to BC and planning

The soil stack has the addition of a loft from last year and although the pipe could be updated to plastic, Id rather avoid moving it. Hopefully having it boxed with a removable panel would be okay.

What im hoping is that the existing rainwater downpipe could be moved to the rear elevation. (temporarily altering the pitch of the guttering to fall to the end of the kitchen and in to a new gully so the cream down pipe would be removed. This inturn would be a box gutter once the extension was built.

Next problem is the two kitchen waste pipes (Sink/Dishwasher/WashingMachine). Can they be ran in to a new drain (substack) that runs the length of the kitchen extension to where the gully is current situated underground.

Hopefully this has worked. Plan is to have blue line as new underground pipe to join where the existing gully is.

Gulley shouldn't be an issue to move along a bit, fit a Bottle Gulley in the new position and the wastes can be dropped into a run of 110mm pipe into the back inlet of the Gulley. Outgoing pipework from the Gulley is accessible from the Gulley, so that shouldn't be a problem either.

Stack, swap to plastic, you dont want to be burying a cast stack inside the new extension only for it to fail and/or start leaking in the near future. Rainwater, as you've said, alter the fall on the gutter, presume you'll reroute the downpipe from above currently going into the hopper, into the gutter.

Thank you.
Would putting a solid floor make any difference as I assumed I would have to consider a steel durabase type floor with the air bricks where the current sliding door is.
Got a SIPs installer coming on Monday to quote for 4.5 x 3m walls with 2.5m bifold door sat in the 3 m rear elevation and a warm roof with two glass inserts for light.
