Soil stack & Building Regs

[microkid]

If i replace part of my soil stack like for like as part of moving my WC do I need to building regs involved / tested?

When done the stack will be identical except the current t for the WC will be 180 round so the WC will connect from other side.

I was planning on replacing the stack from about 1Meter high right the way up.

If I do need building regs am I better off paying a plumber to do this and deal with the regs?

For what my opinion is worth, I would get on and do it and not worry about BR. You wont have disturbed the pipe leading into the drain.

Save yourself all the bureaucracy
