Symptoms
- Water dripping under the sink when the sprayer is used
- Wet cabinet floor near the base of the faucet
- Sprayer feels like it's losing pressure
- Leak only happens when spray mode is active
Likely causes
- CommonLoose hose connection at the faucet body or spray headQuick-connect fittings can work loose over time.
- CommonCracked or worn hoseThe flexible hose can crack from years of pulling and retracting.
- PossibleWorn O-ring at a connection pointSmall rubber seals dry out and fail with age.
- PossibleFailed diverter valveCan send water to the wrong path and appear as a leak.
What to do
- Turn off the water supply under the sink before working on the hose.
- Trace the hose from the spray head down to where it connects at the faucet body and check both ends for looseness.
- Hand-tighten or use pliers to snug any loose quick-connect fittings.
- Turn the water back on and run the sprayer, watching closely along the hose length for the exact leak point.
- If the leak is mid-hose, look for cracks or worn spots; a cracked hose should be replaced rather than patched.
- If the leak is at a connection, turn off water again and replace the O-ring or washer at that fitting.
- Reconnect, restore water, and retest the sprayer at both full pressure and spray mode.
