Awhile back, I asked about a pounding sound I got when running the hot
water. It was like a rapid plumber's hammer. I thought it was coming
from the header, but it sounds now like it's under the sink. The
dishwasher is connected to the same mains, and doesn't cause the sound
when run. Now, the cold water is beginning to make this sound.

The hot water starts to pound (~3 pounds a second) after a few
seconds--about when it starts to get warm. The cold water starts almost
immediately if the cold is opened very wide. If I close it a little,
the pounding softens but the rate will stay the same. If I run the cold
a little more closed, it doesn't happen.

What could possible cause this? Again, this doesn't happen with the
dishwasher. However, if I start the hot water with it running, I get
it, and sometimes it'll continue after I shut off the water. The only
way to stop it is to stop the dishwasher, at which point it stops even
if I restart the dishwasher.

I'm thinking it's time for a new faucet anyways but I'm not up for the
replacement now. It's a ball-type faucet if that helps. I reached
under and it doesn't look like there are any accessible nuts for
tightening the pipe to it.

This all started after I replaced the undersink shutoff valves. I
assume I shifted the copper pipes around a little bit and it's now
causing some trouble. Could it be that I pinched the pipe someplace?

Does the faucet have a spray wand?
If so, either the diverter valve (located in the base of the faucet)
is bad or else the wand itself can be the cause.

If it's the diverter, replacing it may be easier than
ripping out the faucet. The wand is even easier.

The diverter is bad; the spray wand doesn't deliver water at much
pressure at all. I tried to replace the wand and it didn't help.

I can't unscrew the top of the faucet from its base. I've been through
this before, but started to restrain myself when thoughts drifted to
Dremeling between the top and bottom parts of the faucet based to
hopefully dislodge it enough.

Is there some kind of silver bullet for loosening those up? I tried a
plumber's wrench, but it was looking like I'd rip the whole faucet out
rather than loosen the top half.

I had a faucet in my sink that needed to be replaced. Turns out it was one
of those single pipe jobbies where the faucet turned but didn't actually
come off. I eventually took a hacksaw to the brass and cut the goddamn
thing out and bought a nice new modern one that easily installed and only
requires the water supply hoses to come off for removal.
