How many things are wrong here...

Just one really - the entire drain line installation.

And I am assumming that does not count the electrical Ben. ha. ha.

Are the water stains on the joist still damp?

[Michael Roberson]

I count several. First, Grey Pipe being used for a drain, this is electrical conduit. Second, there is a built in "trap" below the floor. Next the glue/ primer is definably the wrong stuff. At least this isn't pressure. There may not be a trap above the floor, and they counted on this one. Im guessing this is a tub drain. The 2" PVC (im guessng here) is narrowed to an 1 1/4" copper drain. Serious flow problems. The strapping is off of the pipe, and there is a Serious electrical feed directly underneath a potential leak.
Nothing that cant be fixed by a good plumber and about 30 minutes of glue sniffing in a basement. Id throw a clean out in there for good measure.

you guys are excellent.

What about the 45 degree sloped pipe? That's not good. Correct?

What about the 45 degree sloped pipe? That's not good. Correct?

I figured that the UPHILL slope made up for that

[Jeffrey R. Pope]

Keeping in mind that what you've pictured is FUBAR, and inconsistent with any normal building standards, a 45 degree slope is not necessarily a problem - nor is it prohibited - for short runs. Anything greater than 45 degrees, however, is considered "vertical" with regard to DWV systems.

They forgot to hack a big chunk out of a joist somewhere, definitely amateur.
I like the way they used the water line to support the first elbow.
BTW, that grey down tube from the tub is probably a hardware store item, designed for an ABS compression fitting. If the white stuff is 1 1/2, that copper drain is only about 1".

Actually, who cares about the 45, they are going to have to remove the whole thing anyway.
