90 degree Drainpipe fittings

[Terry Beck]

See attached photo.
Two 90 degree elbows (I suspect coming from a bathtub) don't look like approved fittings. What is IRC code for this? (I see a table under 2006 IRC P3005.1).
I also assume the Wye fitting is upside down. correct?

What would these 90 elbows normally be used for? Water supply fittings?

How would you call this out in a report?

Just say that nothing about that installation is correct. Tell them to have a real plumber fix that mess.

[Joshua Hardesty]

Yeah. That's a whole lotta mess. Those fittings are typically used for cold water supply outside of a house (not inside) such as for a well pump. They're not DWV at all. Plus, the 3x2 tee is upside down.

Terry,
Those are vent 90's, not drainage 90's.
It's a sanitary tee which is upside down, not a wye.
Hope the buyers don't have long hair. Forget about trying to get a rod through multiple vent 90's

State improper fittings used in DWV piping and sanitary tee is upside. Improper worm-gear hose clamps used on supply piping visible through cut-out opening. Have plumbing contractor correct as needed and verify inaccessible plumbing above is correct.

Stupid question...how do you tell the difference between drain and vent 90's? I've got my suspitions but don't want to insert both feet.

Those are pressure 90's, not vent 90's. Anyways, it really all comes down to the sweep of the pipe. These are line drawings from Charlotte Pipe's website:

Notice that with pressure fittings, the outside diameter of the fitting stays the same; that is to say, there's no visible hub that the pipe slides into like there are the vent, regular and long sweep DWV fittings.

There is no difference between drain and vent 90s. That is why they are DWV ... DrainWasteVent ... and not "90s", but "sweeps"

Those shown are "pressure fittings", not DWV fittings.

Two visual differences between DWV and pressure fittings is that pressure fittings have a sharp radius versus a sweeping bend for DWV, and, pressure fittings did not have a smooth transfer from interior surface to interior surface, whereas DWV fittings do - so they will not catch waste, clog and become blocked up.

Terry, if that is a tub drain it should be 2in. The pipe looks more like 1.5 in. in the photo. Regardless, I have to agree with everyone else that is am amaturish job which more than likely will either eventually plug or leak!

[Jon Bolton]

THanks Jerry!

[Jim Robinson]

Robert, are you sure about the 2 inch for tub drains? I thought that was for showers, and tubs could be 1.5 or 2 inch.

[Robert Dalga]

Opps, I think your right...tubs 1.5 and showers 2. My Bad.

All this and I still dont see a "P" trap for sewer gas

Thanks Joshua, clear as a bell now!
