Thread: Pipe sizes for drain, vent, and distances for Colorado Springs, Colorado

  1. #1

    Default Pipe sizes for drain, vent, and distances for Colorado Springs, Colorado

    Questions on venting pipe sizes for Colorado Springs, Colorado:

    Hello:

    Can someone please tell met the minimum pipe and vent sizes for the following:

    Bathroom sinks with two sinks:
    Minimum Drain size = Minimum Vent size =?
    Maximum distance of vent from P-trap

    Max Drain size = Max Vent size =?
    Maximum distance of vent from P-trap

    Kitchen with two sinks:
    Minimum Drain size = Minimum Vent size =?
    Maximum distance of vent from P-trap

    Max Drain size = Max Vent size =?
    Maximum distance of vent from P-trap


    Laundry room with two sinks and washer:
    Minimum Drain size = Minimum Vent size =?
    Maximum distance of vent from P-trap

    Max Drain size = Max Vent size =?
    Maximum distance of vent from P-trap

    Toilet:
    Minimum Drain size = Minimum Vent size =?
    Maximum distance of vent from P-trap

    Max Drain size = Max Vent size =?
    Maximum distance of vent from P-trap

    Shower & bathtub:
    Minimum Drain size = Minimum Vent size =?
    Maximum distance of vent from P-trap

    Max Drain size = Max Vent size =?
    Maximum distance of vent from P-trap


    How do you upsize the vent pipe size when you combine as follows:

    1) Dual bathroom sinks, shower, bathtub and toilet?

    2) Single bathroom sinks, shower, and toilet?

    Someone told me that if you use a 3" pipe for floor drain, venting is not required. Is this correct?

    When the vent reach the roof, do we have to change the size of vent pipe?


    Is ther a webstie where I can see a table for vent size / drain size, and vent to p-trap distances
    for UPC standards or international standards?

    Thanks,
    kind regards,
    HP

    Default Code Q's

    Yes this was answered on ****.com, and I was the first to reply. I reiterate, go to the library and look in the research section for a copy of your current code.

    Us plbrs, spend 4 to 5 yrs in an apprenticship program to gain our knowledge of plumbing, and most of us are not willing to give it up, to a DIYer; esp. all the knowledge you are looking for. Because of the scope of your Q's, it sounds to us like you are attempting a job that should be done by a licensed journeyman. So please call one, and when the job is done it will be to Code, insured, and guaranteed for a standard length of time (prob. a year).

    Good Luck,
    Rudy
