Things You'll Need
Replacement or repair kit for your faucet
A Gooseneck faucet has a long spout neck that arches over the sink. It is a designer touch that is also functional, because deeper pots can slide under the spout mouth. This style faucet is repaired in the same way any other faucet. Replacing the inner cartridge repairs worn seals, stops leaks and upgrades the performance of the fixture because this part contains all the seals and washers that monitor water flow. It requires little skill to master this fix. If you can change a door knob, you can do this repair.
Turn off the water to the faucet by closing both hot and cold pipe valves under the sink.

Take off the handle to the Gooseneck faucet by removing the handle's cap and loosening the screw under it with an Allen wrench.
Remove the handle sleeve (chrome trim piece), gasket and bonnet (turn counterclockwise to remove). Use large pliers to remove any piece that is stuck or will not remove by hand. Or, if your faucet does not have trim and simply has a retaining nut or bonnet, just remove this piece.
Slide out the old cartridge and replace with a new one from your cartridge repair kit. Replace the bonnet and tighten it. Re-install the chrome trim sleeve and replace the handle. Tighten the handle screw with the Allen wrench to secure it.
Repeat this step on the other handle (if your Gooseneck faucet is a double handle style faucet) and the other handle requires repair.
