Sink Drain question
I just unclogged a TON of the wife's hair out of the bathroom sink (because the water was draining really slow...and no, she's not balding.).
Now, if I fill the sink w/cold water, it drains out faster than HECK and even creates an eddy.
However, if I fill the sink w/hot water, it drains really slow and occassionally, bubbles will come up out of the drain.
What gives? Is there some law of physics that says hot water drains a LOT slower than cold?
Thanks in advance!
