New assignment on Wet Venting.
This site has some good technical explanations of plumbing principles. Like the proportion of water to air flowing in vertical gravity drainage pipes. 7/24ths is an interesting fraction.
Lots of interesting and well done YouTube videos available illustrating all sorts of drainage and venting arrangements. Many reference US and international plumbing codes but quite a few refer to the National Plumbing Code of Canada Like this video from the plumbing department a SAIT in Calgary.
And this video from Camosun
