I just installed a new sink and new peerless faucet with separate cold/hot handles. After a few seconds of turning it on it seems to pulsate almost as if there's air in the lines. The whole faucet pulsates pretty good. It does this in maybe 5-10 second intervals no matter how high or low I have the water coming out. It didn't start doing this until the nest day after installation. No other faucet in the house does this. Could it just be that it's a defective faucet? I've installed quite a few faucets and never had one do this. :confused:

Tell me what side pulsates the most. Hot or cold. Whichever side it happens on then that's the stem and washer assembly you have to remove. Check and tighten the screw on the washer and then turn the hot water on for a minute to flush out the supply. Good luck, Tom

Both sides pulsate equally so I'm assuming that I will need to remove both stems,correct?

Is there a spray attachment?
