I have Moen single-control spray kitchen faucet. Sometimes when you turn it on nothing comes out. First time it happened I thought there was a problem with the water supply but the other faucets worked and then this one started working again too. Next day it seemed fine but then the same thing happened. Sometimes when it isn't working if I pull up on the handle very slowly it will come on but as I continue to raise it up the flow stops. Any suggestions?

Shut off the water under the cabinet and pull and check the inlet ports on the cartridge. If you need instructions click on: http://www.moen.com/consumersupport/...3/moen0133.cfm
Before you reassemble turn the water on to flush out the supplies. Good luck. Tom
