I replaced my kitchen faucet with a new one handle style with the sprayer on the spout. After the replacement was put on there was no water flow. I took the faucet back to the store and bought a $20 two knob faucet and had it put on and there was a water flow. I tried using the sprayer and it was on a short hose so yesterday when I used it I pulled it out and the hose actually enxtended out much more, but when I was finished and turned the sprayer off the water flow from the faucet shut off and will not come back on. The plumber is completely stumped and does not know what to do.

It sounds like you got trash in the valve, so you will have to take it apart and clean it out.

Thanks; I'll try that and let you know what happens.
