Symptoms

- Spout catches or squeaks while turning
- Movement has gotten progressively stiffer
- No leaking, just difficulty swiveling
Likely causes
- CommonDried-out O-ring lubricantThe O-rings that let the spout rotate need periodic lubrication that wears off over time.
- CommonMineral buildup around the spout's swivel baseHard water deposits can accumulate where the spout meets the faucet body.
- PossibleWorn or swollen O-ringsOld O-rings can grip too tightly against the housing.
- Less commonDebris trapped under the spout baseCan physically obstruct rotation.
What to do
- Turn off the water supply under the sink before removing any parts.
- Depending on the faucet design, lift or unscrew the spout off its base per the manufacturer's instructions.
- Inspect the O-rings around the spout base for cracking, swelling, or mineral crust.
- Clean off any mineral deposits with a vinegar-soaked cloth.
- Apply plumber's silicone grease to the O-rings and the inside of the spout base.
- Reattach the spout and test that it swivels smoothly through its full range.
- If it's still stiff, replace the O-rings with an exact-size match and regrease.
