How to Repair a Sink Sprayer

Save

Sprayer units attached to sink faucets are convenient for cleaning pots and pans and keeping the sink free from excess food and debris. Kitchen sprayers are comprised of simple parts such as a sprayer head, hose, activator lever and erator. Some parts of the unit may wear out earlier than others and need replacement. These are easy, quick fixes for most people and should not require a plumber.

Things You'll Need

  • Adjustable wrench
  • Vinegar
  • Soft scrub brush
  • Pliers
  • Screwdriver
  • Replacement parts
  • To repair a clogged or low-pressure sprayer, check if there are mineral deposits clogging the aerator. Remove the aerator from the nozzle head by unscrewing it; clean with vinegar and water or other mild solution and a soft scrub brush. You can soak it in pure vinegar for heavy buildup to help loosen the minerals before scrubbing.

  • If cleaning does not improve your pressure, you may need to clean or replace the diverter valve on your faucet. To test, remove the sprayer head at the coupling, and disconnect the coupling from the hose by snapping off the retainer ring. Turn the water on with the hose held over the sink to see if you get a good flow from the hose. If so, it is your diverter valve. Turn off the water supply to the sink, and replace as needed according to manufacturer's instructions. Diverter valves are specific to sink models so be sure to take it to the hardware store with you to replace with the correct unit.

  • Inspect the hose on the sprayer for leaks, wear or splitting. If it shows signs of excessive wear, turn off the water supply to the unit, unscrew the hose from the plumbing nipple attached to the faucet and drain any existing water from the line into a container. Remove the retainer clip securing the hose to the handle, and replace with a new hose. You may also check the washer contained in the sprayer head for any chips or wear. Detach the sprayer head from the hose and remove the washer, replacing if needed.

  • If the entire sprayer is kaput or close to it, replace with a new unit. Turn off the water supply to the faucet; remove the sprayer from the faucet nipple, draining excess water into a container. Unscrew the nut under the sink that mounts the sprayer base to the unit to remove the assembly. Follow the installation instructions provided with the new unit. Turn the water back on, and test the sprayer to be sure it is operating correctly.

  • If the hose unit is in good condition, you may opt to replace just the sprayer portion of the unit. Simply unscrew it from the hose, and replace with the new head.

Tips & Warnings

  • Avoid using metal objects to unclog hoses or scrape mineral deposits; these can damage the unit.
