I just had a new tub spot installed. It was the screw on type. When running water for the tub, I notice a very small amount of water dripping from the hole on the bottom of the spout directly next to the shower wall. When the shower diverter is up, the amount of water coming through this hole is bit greater. The water travels down the shower tile and into the tub. Is this normal? It seems as though this might be a "weep" hole for this purpose, but I didn't notice this with the old spout. Thanks.

Not normal. Have the plumber come back.

Thanks. I wonder if he used tape?

Did you replace this yourself? I'm betting you didn't.
You have described a slip on spout, (see image) and not a threaded one, (see image).
Threaded spouts do not have a square hole next to the wall.
Slip on spouts leak in this fashion when the copper stub out hasn't had the burrs sanded off the end. This causes the "O" ring to be forced out of position making a poor seal. The solution is to remove the spout, position the "O" ring back in its slot, burr the end of the stubout and lightly grease the end of the stubout.before you reinstall Good luck, Tom

Thanks Speedball1!
No I didn't do the work. The spout was part of a trim kit. It does thread on, but it came with a nylon extension nipple that treaded onto the copper connector on one end, then threaded inside the spout att the other. I don't think the old one had a connection and it threaded well inside the spout. I also think that my guy cut the copper line too far and didn't leave enough pipe to get it all threaded goood. I took it off and saw no teflon tape anywhere.

Your plumber probably used size smaller nipple. Then he was unable to screw it all the way in. Common problem. If you end up "between" nipples lengths, you won't be able to use all threads and drip will occur. Of course, as you said, pipe sealant must be used.

In any case, you have to have him to come back and deal with it before it starts leaking into the wall...

Or you can unscrew the spout, wrap three turns of Teflon Tape around the threads and reinstall the spout yourself if you don't wish to wait and if you have enough stock on the nipple. Good luck, Tom

Thanks again everyone! Yea, he cut off too much, which left the inside nipple much too short. I paid too much not to have it done corrrectly, and someone is coming back out.

You have all been very helpful. I deeply appreciate the advise (and knowledge that I've gained).
