How to Repair a Kitchen Faucet Sprayer

The kitchen faucet sprayer is a handy part of any faucet that is used for virtually anything that you want to gently spray with water. There are three basic things that can go wrong with a faucet sprayer which include the spray head, the hose and the diverter.

Repairing the sprayer.

Always begin with the easiest repairs and work towards the more difficult ones. There is no point in tearing into the faucet if the problem is just a kink in the hose.

  1. Look underneath the sink for the sprayer hose. Trace the hose from the faucet to the sprayer to check for a kink in the hose. A kinked hose can simply occur from items under the sink being pressed up under the hose. Straighten the hose out to repair the sprayer. Move on to cleaning the sprayer head if there is not a kink in the hose.

  2. Turn the water supply to the sink off by turning both hot and cold water shutoff valves to the right. The shutoff valves are located on the back wall underneath the sink. Remove the sprayer head from the hose by grasping the base of the sprayer with one hand and twisting the spray nozzle counterclockwise with the other hand.

  3. Place the entire sprayer head into a dish of mineral deposit cleaner, or vinegar. The end of the sprayer head has small water flow holes in it, which can become clogged. Allow the end to soak for 15 to 20 minutes and then scrub the holes with an old toothbrush. Place the end of the sprayer head back on the sprayer body. Turn the water back on and test the sprayer. Replace the entire sprayer if you are still having problems.

  4. Shut off the water supply and disconnect the sprayer from the faucet. The spray hose is connected to the underneath side of the faucet. Use a pair of pliers to loosen the retaining nut on the end of the spray hose to disconnect if from the diverter. Remove the sprayer by pulling it out from the top side of the sink.

  5. Slide the sprayer hose through the same opening and allow the new sprayer head to sit in the grommet. The grommet is the metal ring that keeps the sprayer in an upright position. Connect the end of the new sprayer hose to the diverter and turn the water supply back on. Test the sprayer to see if it is working. A worn diverter on the faucet itself will cause the sprayer to still not work.

  6. Shut off the water supply one more time. Use pliers to remove the diverter cap at the back of the faucet spout. Located underneath the cap is the faucet diverter. Loosen the diverter with a flat tip screwdriver and pull the diverter out with a pair of needle nose pliers. Place a new diverter in the place from which you removed the old one and turn the water supply back on. The diverter is usually the last thing that will go wrong with a faucet sprayer.
