  1. Thank you so much. Been waiting for you excellent videos. Please keep your Phenomenal work coming more frequently. ๐Ÿ™๐Ÿ™๐Ÿ™

  2. Here in toronto canada i would wet vent the toilet with the lav sink and just increase the size of the lav sink drain to 2 inch and a 1.5 continuous vent

  3. Wet vent it using a dirty arm. Done. DAMN DIY'ers. Note: make that clean out practical and bring it above flood level rim. I completly ignore "buried" clean outs

  4. Nice it would be awesome if you made a app that would teach this information and interact as well. Like different plumbing situations that are common and use United States plumbing codes to help inspiring new plumbers to complete the jobs correctly!

  5. Great video and so informative! Thank you for the diagram! The flex seal I put on as an emergency "temporary" fix 3 years ago is starting to fail.

  6. Most states allow wet venting systems witch means a full bathroom will only have one 2 inch vent plumbed to the roof. The venting in this video is called individual venting it uses much more pipe then wet venting and with wet wanting every time you use your sink your washing out the vent.

  7. why are you individually venting everything? You can wet vent the tub and toilet through the lav. The cleanout at the end of the 3" line isn't necessary there either since you can pull the toilet to snake that branch out. The only place your design would work is in a basement bathroom anyways, with that 3" TY into the 3"Y you already have about 10" of drop from the toilet flange to the bottom of the Y so good luck grading the 3" branch to a stack in a joist space without dropping your ceiling. Sorry but this is NOT how you rough in a bathroom.

  8. Iโ€™ll tell you right now, as easy as he makes this look itโ€™s NEVER this easy lol Iโ€™ve been plumbing for 8 years now and you can draw it up get to the job and have to reroute it. Also you donโ€™t need to do the 3โ€x1 1/2โ€ Y instead a simpler way you can shoot a 1 1/2โ€ Tee off the vent to the toilet no need for all that extra work in this video because itโ€™s a WET vent then

  9. This is how we did plumbing in Australia 60yrs ago, venting every trap is a waste of time and money, all you need is a vent at the beginning of the line and a vent off the main line if the junction line exceeds 10mtrs, never pulls a seal, tried and tested around the world for decades
