Any plumbers out there??

I drained my hot water heater yesterday. As it drained, I had the hot water taps open on all faucets, including the bathtub. After it refilled, all were flowing fine so I shut them off and went on my way. Last night, my wife noticed the hot water just barely coming out on the master bathtub and I could see what looked like smoke coming out but assume it was puffs of air in the line. Hot water pressure is fine every where expect the master bathtub. Do I just need to let the hot water tap run on it until it flows with pressure? Not sure how to fix this. Thanks in advance!

Never heard of that. Have you tried to Google the issue?

Yes and it suggested turning all the taps on to try and flush the air out. No luck yet.
