My kitchen faucet has started surging.

When you turn it on it will sometimes run just fine, but then the water flow starts to slow, and the it starts to surge and knock.

It is just the kitchen sink that does this, no other faucet is surging or knocking.

I replaced the faucet and sprayer, and it made no difference.

There is a hammer arrester on the cold line.

Any ideas?

I voted to buy a new house, but the wife kind of likes this one...

Thanks

Hi Wenyo

If you have replaced the faucet and sprayer and the problem remains then the issue is at the SHUTOFF valves under the sink. Here, there must be a washer that has loosened and is rattling about periodically causing the problem. Either replace the guts to the shutoff valves or replace the shutoff valves with new shutoff valves... problem should be fixed after that!
