New tub and p-trap but tub is slow draining...ideas?

[Ednamae]

Just installed valve trim on new tub with new PVC p-trap and find the tub drains very slowly. The lavatory and toilet drain just fine. There are a few bubbles coming out of the tub drain. The tub was unused for quite a while so could there be air trapped? Could the vent stack be too clogged for the tub but allow enough air for the lavatory and toilet? (Texted plumber who installed tub twice). I have used a different plumber a few times for drain issues at rentals but I was sure it was a clogged drain. Not sure what is going on here. Thanks.

since we do not know HOW the "new P trap" was installed we cannot answer the question, other than to say it is NOT "trapped air", at least not because of not being used.

Try getting the line snaked. Sometimes debris gets into the line during remodels. If all that was replaced was the trap, waste and overflow piping then it's probably not a venting issue.
