I was underneath the house the other day and noticed a couple of combination wyes in the plumbing on their backs/sides.
I know there are differences on which fittings can be on their sides/back and I was curious if these were done correctly. We moved into the house about a year and a half ago and my best guess is that these pipes were redone about 5 years ago - but based on the previous owner's other handiwork I wouldn't be surprised if the entire DWV system is wacky.
First one is the drain from a bathroom sink. The vertical continues as a vent through the roof.
On the second, if you can look past the mess of romex (another project for another day) two toilets connect into the main stack with a combination wye on its side.
