The answer to 'when to replace faucet' is that you should typically replace your faucet every 10-15 years, or sooner if it is leaking, dripping, or not functioning properly. Faucets are an important part of your plumbing system and can wear down over time due to regular use and exposure to water. Replacing a faucet can help improve water efficiency, prevent leaks, and enhance the overall appearance of your kitchen or bathroom.
Some common signs that it's time to replace your faucet include: decreased water pressure, visible corrosion or mineral buildup, difficulty turning the handle, and persistent dripping even after repairs. If your faucet is more than 10 years old and experiencing any of these issues, it's a good idea to consider replacing it to avoid potential water damage and higher utility bills.
