    I am installing all new plumbing on the third floor of my house. I am installing a toilet about 8 feet away from the existing stack. Is there a code for the initial drainage pipe drop from the toilet to the horizonatal line? I know the slope after the drop is a 1/4" per foot.

    The total devolped length of pipe between the vent, and the flange can be six feet.

    Thanks for the quick response. What about right below the toilet, does there need to be an initial straight vertical drop or can I 45 it and then do my slope?

    You can angle it. Or drop it straight for a while.

    They even make a flange with a 45 elbow built in...
    Make sure that if you use a PVC/ABS flange that you use one that has a stainless steel ring...

    Why? PVC won't rust either or are you saying it will eventually crack/break?

    We do see some bad plastic flanges later on.

    OK. Is one stainless model any better than the others or will pretty much any flange with a SS ring from a big box suffice? I'll be going into 3" PVC (and won't be getting one that fits inside the pipe :) ).
