A click or a knock from a faucet when it opens or closes is the internal parts moving, and it can be normal or a warning. Knowing the difference keeps a small noise from becoming a repair.
The normal
Some cartridges and valves click as they seat, which is the mechanism working, and a single click at open or close is often fine. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Union City, it is the repeated or loud clicks that matter.
The hammer
A knock that travels through the pipe when the faucet shuts is water hammer, and it needs an arrestor rather than a faucet part.
The loose
A rattle as the water runs can be a loose handle, escutcheon, or supply line, and tightening the parts stops it.
The worn
A clicking that gets louder or happens every time may mean a worn cartridge or diverter, which is replaced.
