    How much slope is required once I have the p-trap installed.
    The abs pipe is approx 10in long before it elbows straight down . This is a new install washroom with the builder having done the rough-in 5yrs ago.Also I must move the abs to the right about a in so it will line up with my pedestal sink.
    Thanks

    Hi Shawn,

    I hope you aren't telling me this doesn't have a vent.
    For a 1 1/2 or 2" drain the sloipe is 1/4" to the foot.
    I must move the abs to the right
    The trap should swing over a inch so you can install your lavatory. Good luck, Tom

    Is that 10 feet of horizontal "dirt arm" connecting P-trap and vertical drain ?

    Milo, That's 10 inches not 10 feet.

    Does it sound like it's vented to you? Regards, Toim
