    Tub drain need to drop 26", btr to drop at 45 or 90?
    Hello All,

    I'm installing a shower and have been scratching my head on this for a while.

    I need to run the drain along the wall above to so I can vent it (for a foot or two), then hang a right and head toward the stack about 5' away.

    Due to the small crawl space and T on the stack, I need to drop about 24" over 5'.


    Is it better to go 5' then drop straight down, or go 2.5 feet and head down at 45 degrees?

    Thanks in advance!

    Hi Chip

    Great question here! In fact, you are better to run the 5 feet, pitching the pipe at 1/4" pitch per foot of piping, and then drop straight down. In this way, the solids won't get left behind in the horizontal pipe as they would if you exceeded anything beyond 1/2" pitch per foot of piping, OK?

    If you have more questions just let me know, OK?

    I hear you, Harold... LOL!

    I answered the question in terms of a plumbing generalization... as you know, always better to drop at proper rate of slope on horizontal pipes than to drop off too quickly!

    Just wondering what goes down your shower after a hard days work.

    Do you need any new tools?

    If you really think about how dirty a plumber gets some days... you can imagine the solids going down my drain... :)

    Loved the video by the way... the future is now, huh?

    Thanks!
