Understanding the Problem
A broken kitchen faucet sprayer (the pull-down/pull-out wand or separate side sprayer) commonly fails because of a clogged aerator, worn seals, a failing diverter valve, or a damaged hose. Symptoms range from weak or intermittent spray, constant trickling from the spray head, to leaks at the base of the wand or under the sink. Because the sprayer assembly combines moving parts and flexible hose, the cause is often mechanical wear or mineral buildup rather than a problem with the water supply. Diagnosing the exact faulty component means isolating where the issue appears: the spray head (nozzle blocked, internal check valve failed), the diverter (won't switch flow between spout and sprayer), the pull-out hose (kinked, split, or leaking), or seals/O-rings (leaking where the wand connects). With a few simple tests and visual checks you can usually determine the part to replace and whether a full spray assembly swap is necessary.
Common Symptoms
Weak or no spray, sputtering/air in the stream, continuous drip from the spray head, water leaking under the sink or around the faucet spout, or the spray function failing to return to the main spout.
Common Causes
- Mineral buildup or clogged nozzle/aerator in the spray head
- Worn or stuck diverter valve prevents switching flow
- Damaged, kinked, or split pull-out hose or bad O-rings/seals

Helpful Repair Tip
To confirm the faulty part, disconnect the spray head and run water through the hose: if flow improves, replace/clean the spray head; if the hose leaks or flow is poor with the head removed, the hose or diverter is likely the problem.
Frequently Asked Questions
Why does my spray head only drip or sputter?
Sputtering or dripping usually means the spray head nozzle or check valve is clogged with mineral scale, there is air in the line, or the diverter isn't fully routing flow. Remove the spray head, check and clean the aerator/nozzle and internal screens, then test the hose with the head removed to isolate the problem.
Can I fix a leaking sprayer myself or should I call a plumber?
Many sprayer issues can be fixed by a confident DIYer: cleaning the spray head, replacing O-rings, swapping a hose, or installing an OEM diverter are straightforward with basic tools. If the leak is inside the faucet body, requires shutting off complicated valves, or you can't identify the matching replacement part, calling a plumber avoids trial-and-error and potential water damage.
