No water comes out of my kitchen faucet when I turn it on. Every other water outlet in the house is working fine, and the kitchen faucet was working fine until the last time we used it (two days ago). There is no trickle, it just doesn't work. I turned to shut-off valves on and off completely but nothing happened.

It's a single handle faucet with a built in sprayer. I took off the handle and also looked under the sink to see if there is anything obviously wrong or broken but either there isn't or I don't understand enough to be able to tell.

I'm happy to take the faucet off to look deeper, but the problem is I don't know what to look for. I would love any advice about how to proceed before I call a plumber.

  • Does the tap feel easier/harder/different to move and turn on than normal? – Grant Nov 30 '13 at 0:46
  • No, it feels the same as usual I would say. – Sonny Nov 30 '13 at 1:31
  • Are you sure there isn't some other valve upstream of your sink that is closed? It's very odd for the faucet to suddenly completely stop flowing or at least leaking unless it has been worked on recently. – Shimon Rura Nov 30 '13 at 3:38
  • The last time that happened, we had the nipples between the copper elbow and the under-sink shutoff valve rust completely shut. The 1/2" iron nipple was a solid block of rust inside. We replaced every nipple in the sink supply lines with 1/2" copper NPT and haven't had an issue since. – Fiasco Labs Nov 30 '13 at 4:16
  • Shimon: I have checked every other water supply in the house (and I'm sure of it because I have a very small house) and they all work fine. About a month ago I turned off the main supply to the house, emptied all of the water lines with the intent of hopefully fixing a water hammer issue in the laundry room (it worked), but no other work has been done recently.\\ Fiasco: Did the rust have a gradual effect or did it happen suddenly? – Sonny Nov 30 '13 at 4:56
