plumbing in new toilet

[wallyworld]

i am installing a new wc, the plan is to dig down and expose the soil pipe that is running below the planned site. the pipe i am going to attach to only has one other toilet attached, about five feet away. i was just going to attach an equal tee connection, and then plumb straight in, is there any complications with not adding a sub stack? i am a keen diy'er and am a little daunted by this job. is it quite easy? anything i need to think about?

Anything i need to think about?

You need to inform BCO who will want to inspect it and see if you need a sub stack.

You need to consider the Building Regulations !

A qualified plumber who is a member of a scheme can do the work and self certify and notify the Building Control afterwards.

A DIYer has to submit drawings and have them approved and the work inspected. They are very fussy about soil drains.

oh, didnt consider that! do they frequently turn down this type of request, or is that a bit of a big question?

No, they cannot turn it down as long as the drawings meet the requirements of the regulations.

They can be a little fussy though.

An air admittance valve might be required in your case as an alternative to a new soil stack.

I am not an expert but I think that if there is a stack further up the drain then an admittance valve will be acceptable.

The scheme member doesn't have to be a plumber. Most plumbers don't do underground drainage work.

A DIYer has to submit drawings and have them approved and the work inspected.

This isn't correct - notice can be given and work started by a DIYer, with staged inspections by the BCO, and the drawing doesn't have to be detailed.

However, rather rely on the sometimes dubious advice given here, why not contact your LABC and ask them to explain the procedure.
