Fixing a kitchen sink sprayer typically involves diagnosing the specific issue—whether it's a leak, clog, or malfunctioning spray mode switch—and then performing targeted repairs. Most problems can be resolved by replacing the spray head, hose, or internal components like springs or O-rings, with many repairs requiring only basic tools and under two hours of work. Common solutions include disassembling the sprayer to clean mineral deposits, stretching or replacing a stuck spring, or installing a new spray head or hose assembly.

Key findings from the sources:

• Leaking sprayers often require replacing the spray head or hose, with O-ring failures being a frequent cause ^[1][9][10]
• Sprayers stuck in spray mode usually need the internal spring adjusted or replaced ^[2][4]
• Clogged sprayers can often be fixed by soaking the head in a descaling solution like CLR ^[6]
• Full replacement of the sprayer or hose is straightforward and involves basic plumbing steps like turning off water, removing mounting nuts, and reconnecting components ^[3][7]

Common Kitchen Sink Sprayer Repairs and Solutions

Fixing a Leaking Sprayer

Leaks in kitchen sink sprayers most commonly originate from the spray head, hose connections, or worn O-rings. The repair process varies slightly depending on the leak's location, but most solutions involve disassembly and component replacement. For leaks at the spray head, replacing the entire head is often the simplest fix, while hose leaks may require tightening connections or replacing the hose assembly.

• Spray head leaks are typically resolved by:
• Removing the old spray head by unscrewing it from the hose connection ^[1]
• Detaching the C-clip and base of the old head before installing a new one ^[9]
• Ensuring the replacement head is compatible with your faucet model, as some brands offer lifetime warranties ^[6]

• Hose connection leaks often stem from:
• Worn or damaged O-rings at the connection points, which can be replaced by:
• Carefully removing the hose without scratching brass fittings using a plastic tool ^[10]
• Noting the O-ring size and purchasing exact replacements at a hardware store ^[10]
• Applying plumber's grease (not petroleum jelly) to the new O-rings before reassembly ^[10]
• Loose mounting nuts under the sink, which can be tightened with a basin wrench ^[7]

• Persistent leaks after component replacement may indicate:
• A faulty diverter valve in the faucet body, which may require professional servicing ^[5]
• Corrosion in the hose or sprayer assembly, necessitating full replacement ^[3]

For all leak repairs, begin by turning off the water supply under the sink and testing connections with the water on before finalizing the repair. The Home Depot guide emphasizes checking for leaks immediately after reassembly to avoid water damage ^[3].

Restoring Spray Mode Functionality

When a kitchen sprayer becomes stuck in spray mode or fails to switch between stream and spray, the issue typically involves the internal spring mechanism or diverter valve. These problems are common in older sprayers and can often be fixed without replacing the entire unit. The repair process involves disassembling the spray head to access and adjust or replace the spring that controls the spray pattern.

• Diagnosing the problem:
• Sprayers stuck in spray mode usually have a compressed or displaced spring inside the head ^[2]
• A sprayer that won't switch modes at all may have a broken diverter valve or lever mechanism ^[5]
• Mineral buildup can also impede the switching mechanism, especially in areas with hard water ^[6]

• Spring adjustment/replacement process:
• Begin by unscrewing the spray head from the hose connection ^[4]
• Remove the plastic insert inside the head to access the spring, which may fall out during disassembly ^[4]
• For a stuck spring:
• Stretch the spring gently to restore its tension (this often resolves sticking issues) ^[2]
• If stretching doesn't work, replace the spring with an identical part from a hardware store
• Reassemble the spray head, ensuring all components are properly aligned before screwing it back onto the hose ^[2]

• Additional troubleshooting steps:
• For diverter valve issues (where water doesn't switch between faucet and sprayer):
• The valve may need cleaning or replacement, which requires accessing the faucet body ^[5]
• This repair is more complex and may necessitate professional help if you're unfamiliar with faucet disassembly
• For mineral-clogged sprayers that affect mode switching:
• Soak the disassembled spray head in a 50/50 vinegar and water solution for 30 minutes ^[6]
• Use a small brush to clean the internal components before reassembly

• Preventative maintenance:
• Regularly clean the spray head by soaking it in descaling solutions to prevent mineral buildup ^[6]
• Avoid forcing the sprayer lever when switching modes, as this can damage internal components
• Consider installing a water softener if you live in an area with hard water to extend the sprayer's lifespan

The Lex Vance YouTube tutorial demonstrates that spring-related repairs typically take less than 5 minutes once you've disassembled the spray head, making this one of the quickest fixes for sprayer functionality issues ^[2]. For persistent problems after spring adjustment, full spray head replacement is often the most time-efficient solution.
