Why is my bathroom sink so slow? Could it be air in the line? If so , what do I do?

Question

Water is extreamly slow draining, even after using a Drain Cleaning Bladder.

Answer 1

You failed to specify if it's slow to fill, or slow to drain.

Answer 2

Try filling the sink with hot water and then hold something over the overflow hole while plunging the drain hole.  This will create a good plunging preasure.

Answer 3

you need to take apart the p-trap and run a snake down the drain to clear it

Answer 4

If it drains slow....it just needs the cleaner to be run through it. If its the water pressure you may have some clogs in the line or valve.

Answer 5

First, a question: Is it the drain that's slow, or is it the water pressure?

If it's the drain, the P-Trap may need to be cleaned out, and the stopper as well. You would be surprised at how much hair can gather in there over time.

If it's the water pressure, remove and clean the aerator first. They can become clogged with tiny bits of debris, slowing the flow of water quite effectively.

It's not likely that you have air in your lines, as air almost always extricates itself when it forms in plumbing lines.
