Causes of Kitchen Sink Sprayer Not Turning Off

The sprayer may not shut off because the lever is dysfunctional. It may mean you need to replace the handle, its seat, or the stem washer. If the handle is functioning well, there is usually a problem with the diverter. It is the valve that sends water from the spout to the sprayer. Usually, the valve lies near the base of the spout. Changing it may be your best option because it is cheap.

How to Fix a Kitchen Sink Sprayer that Won’t Shut Off

To fix the kitchen sink sprayer you will need:

Kitchen Sprayer faucet
  1. Needle-nose pliers
  2. Adjustable pliers
  3. Penetrating oil
  4. Dinner knife
  5. Coin
  6. Rag
  • To stop a sprayer that won’t stop spraying, use one hand to hold the sprayer. On the other hand, work a dinner knife under the lever and push down on the valve button. When the water is running, the water pressure helps close the valve.
  • Once the sprayer is closed, turn off the faucet and lubricate the valve button with penetrating oil to make it glide more easily.
  • If you can’t push the valve in or it won’t stay in, turn off the hot and cold-water valves and remove the sprayer from the hose with adjustable pliers. Purchase a replacement sprayer from your local hardware store. It is easier and less expensive than disassembling and attempting to repair the sprayer.
  • Change the diverter if water flows to the sprayer every time you turn the faucet on. The diverter lies beneath a cap at the base of the faucet in two-handled faucets. Turn off the shutoff valves and use adjustable pliers to unscrew the cap. To protect the finish on the cap, wrap a towel around it before gripping it with the pliers.
  • Use a penny to unscrew the diverter, then needle-nose pliers to pull it out. Replace it with a new one from the hardware shop, then drop it in and tighten it with the coin. Return the cap to its original position.

How to Maintain Your Kitchen Sink Sprayer

The equipment requires regular maintenance because of the makeup of tap water. Elements of the sink sprayer exposed to the liquid are prone to clogging from debris and mineral deposits. You clean the sink sprayer thoroughly to resolve poor functionality difficulties caused by the debris.

If regular cleaning with mild soap and water isn’t working, disassemble the sprayer. Clean the necessary parts with white vinegar or scrub the residues with a cloth or toothbrush.

Using 50/50 mixture of white vinegar and warm water:

  • Clean and wipe the hose
  • Clean the nozzle using a cloth/toothbrush to scrub the nozzle holes
  • Dry the hose

Before using the sprayer to rinse food or fill a water glass, run super-hot water through the flow holes for a few minutes. It helps to clear any leftover debris or vinegar solution.
