    I’m a building inspector and this was solid information with good visual references. Wish my study guides were as useful as this when I was getting my certs years ago.

      Great to hear and I would have loved something like this when I was learning.

    Thanks. Plumbing is an area I am not a fan of. I feel like I gained a better understanding of how and why certain sized pipes are used in plumbing. My mother in laws kitchen sink always backs up at least once a year and it’s 3 hours of an electric drain rotor to clear that thing.

    There was no mention about the drain pipe size in relation to the distance from the fixture e.i. does a 2" drain from a tub have to be larger when the distance is greater than 5 ft to the main waste line?

    Hey boss, I’m wondering on how your getting these fixture unit values ? I’m using 2018 IRC and on table p2903.6 and I’m getting different unit values than you are.

      Okay, the p2903.6 isn’t valued as load factors never mind, thank you sir for the video.

    So.. crazy thought what if I had a drain for the toilets in the bathrooms but had both the sink and the shower (no tub) in the floor pan and incorporated the entire room as a shower floor pan. In essence making the bathrooms into wet rooms.

      I would think it that would work with a two inch drain, but you would need to check with local building department to verify.

    As pipe of different size is not much different in price, why not use 3in everywhere?

    • @gregvancom

      I like it, but you will have to reduce the pipe with some fixtures like sinks and bathtubs.

      Oversizing the pipe can be just as bad as undersizing it because there won't be enough velocity in the pipe to clear solids. Also 3" pipe is still more expensive and the cost adds up. It's also more work to get a larger diameter pipe where you need it while maintaining proper slope.

    Actually boss laundry drains are 3 not 2. 2” p trap is 3 dfu. Sinks 1-1/2” p trap is also 2 fixture units not 1.

      Always Check Local Building Codes Before Building
      It looks like you're referring to a laundry group, but let me know if you're not.
      TABLE P3004.1 DRAINAGE FIXTURE UNIT (d.f.u.) VALUES FOR VARIOUS PLUMBING FIXTURES - 2021 International Residential Code Book
      Laundry group (clothes washer standpipe and laundry tub) is 3 units, Clothes washer standpipe is 2 units
