Common causes
| Cause | Likelihood | Difficulty | Part often needed |

FAQ
How do I know if my sink hose faucet needs a new washer?
If the faucet leaks when turned off or drips continuously, the washer is likely worn and needs replacement.
Can I use regular tape instead of plumber's putty?
Plumber's putty is recommended for sealing faucet parts, but Teflon tape can also be used on threaded connections.
Why is my faucet making a whistling noise?
A whistling sound is often caused by a clogged aerator or a faulty cartridge. Clean the aerator or replace the cartridge.
How often should I replace O-rings in my sink faucet?
O-rings should be inspected every 1–2 years and replaced if they show signs of wear or cracking.
What if the water pressure is still low after cleaning the aerator?
Low pressure after cleaning may indicate a larger issue, such as a clogged pipe or water supply problem. Contact a plumber for further inspection.
