This video shows some very good information and tricks of the trade on how to to install the plumbing of a shower drain in a basement.

u always use wyes on drain piping it’s called directional flow , it also is done in case the drain backs up and needs to be cleared the drain cable will flow out to the sewer and not end up going the wrong way like up thru your roof vent

Nice job but…Plumbing Helper is 100% correct to U.S. code other than the use of 90° bends on their side is not allowed by code. Or the total length of 2inch allowed to be buried.
The correct install would have been use of tbe sheilded ferncos as Plumbers Helper mentioned and 3″ pipe run to tbe venting point. Achieved by a short piece of pipe in tbe why branch to a 45, back to the wall and 45 to straighten the run to the shower vent.
Otherwise nice and neat work.

Jacob Ramirez says:

I was wondering about the 90° but after seeing what your work in on it’s good, nice job.

Katy HackerSpace says:

Where is your vent pipe?

Smitty says:

to correct my auto correct before im haggled, the correct spelling is wye, not why.

Nice video work and commentary. You showed mostly what not to do when it comes to rough-in drain plumbing below grade.
Viewers, please take note:
1) This must be filmed in Canada. Combining ABS and PVC is not normal in the US. If it’s ABS (black), stay with ABS. If it’s PVC (white), stay with PVC. In the US, if you need to attach PVC to ABS or vice versa, this connection uses a rubber, steel-banded coupling.
2) The tie-in at the main drain where he breaks the ABS 3-inch stack pipe and splices in PVC, it looks like there is a “landscaping” 3-inch 45. Landscape PVC is thinner than Drain Waste Vent (DWV) PVC. Landscape PVC is also not allowed for use in DWV plumbing applications, like this.
3) The drain line has no vent. A vent is required for traps that are more than a certain distance from a stack (depending on pipe size). The vent helps remove suction that is generated in the drain line as water is flowing through it. If the suction is great enough, water can be pulled from the trap and break the trap’s water seal. The water seal prevents the sewer gas from entering the house through the drain line. The seal is actually, roughly, 1 1/2 inch of vertical water sitting in he trap.
4) Although this is critiquing his technique, installing 2 90’s (that should be long-turn 90s) isn’t the best design. 45’s would have been better.

Fail. Stick to carpentry, that’s why plumbers apprentice 5 years then take a state exam

Brian Crandall says:

Why didn t you use long sweep 90 s on the 2 inch drain?
