Thoroughly understanding proper plumbing drainage & venting rules creates FLEXIBILITY!

Every plumber knows how to rough-in and install the typical 3-fixture bathroom group, consisting of a toilet, lavatory and sink or bathtub. Almost always, the de facto solution would be to wet vent them together!

But what happens when you throw a FOURTH fixture into the mix...in this case a 2-inch floor drain serving a sauna room?

This is the situation a recent viewer posed to me with respect to plumbing work in house they were renovating...which led down to a whole rabbit hole of Basic Plumbing 101 goodness respective to drain waste and venting plumbing systems!

This twenty-minute video is chock-full of plumbing goodness and know-how...and touches on all kinds of topics imperative ways on how to rough in plumbing properly, from wet venting & individual venting rules, to air admittance valves (affectionately known as "cheater" vents in the trade), and even to sewage ejector...and all kinds of other plumbing rough in basics!

Hope this brings you all some value, and you enjoy it as much as I did making it for you all! 🙏
