Saw one of your other posts about access to the top of the soil
stack. Is that an internal stack? Connecting into that would be
better than the bucket and alarm, though not totaly sure about the
regs.

It is external. It will require a longer pipe run across the loft and will
be a source of annoyance to SWMBO. If I aim the pipe carefully it will only
have about 8" external.
