Kitchen Faucet Sprayer Not Working
When the main kitchen faucet flows normally but the pull-out or side sprayer is weak, the problem is usually local to the spray head, hose, or diverter valve. Mineral buildup can block the nozzle, and a hose can kink under the sink as it moves. These are manageable homeowner checks as long as you shut off the water first and protect the cabinet from drips. Stop and call a plumber for a leaking supply connection, damaged shutoff valve, corrosion, or a faucet that will not stop running. A useful first distinction is whether the main spout has strong flow: if both outlets are weak, the issue may be upstream of the sprayer. If the spout stays strong while the spray pattern deteriorates, cleanable debris or a worn sprayer component is much more likely. Take a photo of the faucet model label or save its manual before ordering parts, because pull-down heads, hoses, and quick-connect fittings are not universal.

Common Symptoms
- Main faucet flow is normal but the sprayer is weak or dead
- Spray pattern is uneven, sputters, or sprays sideways
- Sprayer hose catches, kinks, or will not retract
- Water comes from both the faucet spout and sprayer at once
- Water leaks under the sink when the sprayer is used
Most Likely Causes
- 1
Clogged spray head or screen
Hard-water minerals and small debris collect in the nozzle or screen, restricting flow and creating an uneven spray pattern.
- 2
Kinked or damaged hose
Pull-out hoses move every time the sprayer is used. A kink, snagged weight, split liner, or loose quick-connect can restrict water or leak inside the cabinet.
- 3
Failed diverter valve
The diverter directs water from the spout to the sprayer. If water keeps coming from the spout, the diverter may be worn or blocked and usually needs a model-specific repair.
- 4
Supply or shutoff-valve problem
Low flow at both the spout and sprayer can come from a partly closed valve, supply restriction, or broader plumbing-pressure issue rather than the sprayer itself.

Quick DIY Checks
Stop and close the water supply for an active under-sink leak, a split hose, a loose supply connection, or water near an outlet, disposal cord, or dishwasher wiring. Dry the area and call a plumber if the leak does not stop.
Always close both faucet shutoff valves and relieve pressure before loosening a sprayer hose. Do not force corroded valves or fittings; breaking one can cause a larger leak.
Do not mix cleaners or use harsh chemicals inside a faucet. They can damage seals and contaminate the water path.
- 1Step 1 — Put a towel and shallow pan under the sink. Check whether the main faucet has normal flow; if it does not, stop troubleshooting the sprayer and investigate the faucet supply or whole-home pressure instead.
- 2Step 2 — With the faucet off, inspect the exposed sprayer hose for kinks, abrasion, a loose weight, or a wet connection. Do not pull on a stuck hose or use pliers on plastic quick-connects.
- 3Step 3 — Unscrew only the removable spray head if your model allows it. Rinse the screen and soak the nozzle face in white vinegar according to the faucet maker's cleaning guidance; never force a sharp tool into a spray opening.

Repair vs Replace
A blocked nozzle or kinked hose is inexpensive to correct, and many faucets accept replaceable sprayer parts. Replacement is more sensible when the faucet body is corroded, several internal parts leak, or model-specific parts are no longer available.
Est. Repair Cost
$0–$20 for cleaning supplies; $25–$150 for a hose, spray head, or diverter repair
Est. Replacement Cost
$180–$700+ for a new kitchen faucet with installation

Frequently Asked Questions
- Why does my faucet work but the sprayer has no pressure?
- The spray head screen, hose, or diverter is usually restricted. Start with external hose and nozzle checks; if the spout and sprayer run together, a failed diverter is more likely.
- Can I soak a faucet sprayer in vinegar?
- Usually, yes, for the removable spray head or nozzle face when the manufacturer permits it. Keep vinegar away from unapproved finishes and do not soak the whole faucet body or use harsh chemicals.
- Why is my kitchen sprayer leaking under the sink?
- The hose, quick-connect, or spray-head connection may be worn or loose. Shut off both water valves, dry the cabinet, and have a damaged hose or fitting repaired before using the faucet again.
