FAQ
How often should I replace the O-rings?
O-rings typically last for several years, but they can wear out sooner if the water is hard or if the faucet is used frequently. Inspect them annually and replace as needed.
Can I use any type of grease on the O-rings?
Use plumber's grease specifically designed for O-rings. Avoid using petroleum-based greases as they can degrade the rubber.
What if the faucet still leaks after replacing the O-rings?
If the leak persists, the cartridge or valve seat may be damaged. Inspect and replace these parts as necessary.
