moving a bathroom

[jpm321]

I have just had an extension built and need to move the bathroom currently there are hot/cold 22mm pipes serving the bath and 15mm from the 22mm for the sink and toilet

Would it be ok to join 15mm to the existing main 22mm pipes and the branch off for the bath sink and toilet feed i know 15mm is ok for sink and toilet as was before, just concerned about 15mm to the bath,

i have a potterton suprima boiler

also can you have 2 90 degree bends in a toilet foul pipe?


thanks in advance

You'd probably be better of extending the 22mm into the new room then teeing off as before.

As for the toilet waste - the fewer bend the better ! If you are trying to get back to your original stack in the horizontal plane (just trying to guess) then the fall could be a bigger issue.
