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.

The combos are fine. A sanitary tee would be improper.

The strapping used is a bit hokey, as is the NM wire that could use some cable staples.

Thanks for the replies!

If you think the strapping and NM look hokey - you don't even want to see the rest of the basement! We gutted the upstairs and started over - it was bad.

Hey, wait a minute.

This is awkward, but...
