Summary of rules in video: 1. Max distance from trap to vent: 2x pipe diameter in feet. 2. One horizontal drain 90 allowed before the trap. 3. Horizontal to vertical drop: Use a tee footing. 4. Horizontal to horizontal: Use a Y footing. 5. Vertical to horizontal drain: Use a Y footing, or a long turn 90, or a combo tee fitting. 6. ½ Inch water lines can supply three fixtures (e.g. single faucet vanity + water close + single valve tub) 7. ½ inch water lines tap off of ¾ or 1-inch lines with ½ inch pipe, to fixtures. 8. IF more than three fixtures, tap ¾ or 1-inch lines with ¾ inch. Then tap off ¾ to ½ to fixtures. 9. Full body showers require ¾ in supply to valves. 10. 3 or more toilets require a 4-inch drain pipe from the lowest toilet. 11. Shower drains can use 1 ½ drains pipes (convenient for tub to shower conversions). 12. Horizontal drains: Never go larger to smaller in downstream direction. 13. Never install drain or supply lines where they can free. 14. Sharkbite fittings will require planned access 15. Any trap that doesn’t have easy access needs to be a glue trap. 15.1. I think a glue trap is the one-piece PVC type trap (typically under floors and other inaccessible places) , as opposed to “union traps” (typically accessible under sinks).

Love the example. Nice job. Hate the music.
This is super educational. Thank you for making the video! Do these rules apply to US or other country?
Is that a sketchUp model? Can I get a copy?
