A year or so ago a new water meter was installed and when I turned the kitchen
faucet on it sounded like it was ripping apart. I call it chattering or
chugging. It was a heavy vibrating that seemed to be in the faucet. I listened
under the sink while someone turned the water on and it didn't seem to be in the
pipes below the faucet.
I called the water company that installed the new meter and they thought is was
air in the system and told me to open the faucet and let thr water run awhile.
That didn't help.
This continued for several months then finally stopped.
A couple months ago my water line that runs from outside to the meter in the
cellar busted and I had to have my yard dug up to have it replaced. Again, when
the kitchen faucet is turned on it chatters. I have to turn it on a little and
let in run about 5 seconds, then turn it a bit more, etc. until it is on fully.
I tried turning it all the way on with one turn and it sounded like it was going
to pop apart.
The contractor who installed the new line suggested air in the line. I called a
plummer and he said it may be the diverter.
I did find if I remove the aerator from the faucet, it doesn't chatter, but as
soon as I put it back on, the noise starts again.
Any suggestions what may be causing this? I get used to turning the water on
slowly, but it has surprised a couple friends.
