Symptoms

  • Spray comes out unevenly or in a few strong jets
  • Spray head sputters air along with water
  • Main faucet stream is fine but sprayer is weak
  • Spray pattern has gotten worse gradually

Likely causes

  • CommonClogged spray head nozzle holesMineral deposits clog the small holes that create the spray pattern.
  • CommonClogged diverter valveThe valve that switches flow between spout and sprayer can scale up.
  • PossibleKinked or clogged hoseRestricts flow before it even reaches the spray head.
  • PossibleAir trapped in the line after recent plumbing workUsually resolves after running the faucet for a minute.

What to do

  1. Unscrew or unclip the spray head from the hose, consulting the manufacturer's instructions if needed.
  2. Soak the spray head face-down in white vinegar for 30 minutes to dissolve mineral buildup.
  3. Use a toothbrush or toothpick to clear any holes that are still blocked after soaking.
  4. Rinse thoroughly and reattach the spray head to the hose.
  5. Run the faucet on full stream for a minute, then switch to spray to check if pressure improved.
  6. If it's still weak, check the diverter inside the faucet body, which may need cleaning or replacement per the model's instructions.
  7. If diverter access looks complex for your faucet, this is a reasonable point to call in help.
