Hoping someone can help me out here. I bought a duplex about a year and a half ago and on both sides we have had a problem that when you turn on the kitchen faucet, the water won't flow. If we turn the handle back to a slower flow it will eventually start coming out, but will sometimes vibrate the faucet. If we turn on the faucet very slowly it will usually flow, but once you get it to a certain flow volume it stops again. Any ideas out there????
