 Basic Bath Sink Stub Out Question
Author: cakins (MO)

Just a basic question about the stub out for bath lavatory to prepare for inspection. How long is the stub out supposed to be? Is the inspector looking for a certain length?

Also, does the method of stubbing out depend at all on how the final p-trap from the sink is connected (glued vs. slip joint or hidden vs. visble)?

Thanks. Finally calling for bath rough-in next week after WAY too long.

The length of the stub out, AND its location is strictly cosmetic. You can do them anyway you desire, and the inspector would care less as long as they do not leak. IF you screw up, however, he may have a problem after the sink is connected.

Thanks.

I realize I didn't specify in the original post that I'm only talking about drain stub out

As long as the rough is not to high,Or the bowl drain is not exactly centered with branch arm outlet.You will have room to adjust to the drain.On pedestals and some close to the wall bowls having the drain off center makes it easier.In some exposed installs we do not glue the stub out so fitting type trap adapter may be used.Good Luck.Or the adapter is installed and threaded cap used for test.

Immaterial. Water or drain, you put them anywhere you want to. If it is too short or in the wrong location, that will be your problem when the time comes. That is not the inspector's concern.

They don't sell orange snap on test caps where you are?

Can you clarify this statement above? Right now I've got a 90 degree turning out to the room, but don't yet have a straight stub out glued to that. Are you saying you just leave it like that for the inspection then determine the specific trap and adapter later?

I'm not sure what you meant by "fitting type trap adapter."

Thanks.

you need to stub out a piece of pipe and cap that so you can test the rough

if the end of the elbow sticks out beyond the inside edge of the 2 x 4, you can plug that end for a test. or you can simply glue in a nipple and cap/plug it.
the elbow must be a long sweep.

If the elbow is close to the finish wall, then, yes, just put an orange test cap/plug into it. A fitting trap adapter is a street, or spigot, adapter that goes into the elbow rather than onto the pipe.

Maybe it SHOULD be, but I have never used one at that location.
