Common Reasons for Faucet Failure After Installation

Are you determined and prepared to install a faucet or sink by yourself? If so, familiarizing yourself with common issues that often arise is crucial in ensuring early detection and intervention. Let’s delve into the problems that may arise right after the job is done and effective troubleshooting steps.

Leaks

The most frequent issue after sink installation projects is leakage. Check the area around the base of the fixture for signs of water escaping, usually a result of O-ring, gasket, or mounting putty problems. In such cases, disassemble the entire connection and ensure the mounting nuts or bolts are securely tightened. Also, ensure the putty or gasket creates a complete seal.

If the leak is under the sink or around drains, it suggests a drain assembly issue that requires quick action. Use a wrench to tighten the large nut securing the drain body to the sink and ensure the plumber’s putty or gasket is correctly sealed between the sink and the flange. In case the leak persists, call a licensed plumber in Anaheim, CA to address the root cause and ensure everything is in top shape.

Low or No Water Pressure

Nothing is more frustrating than a weak or nonexistent water flow after turning the supply back on. The cause is often debris, so check the aerator for clogs such as pipe scale, debris, or mineral deposits that were flushed through the line during installation. Gently unscrew the aerator at the tip of the faucet spout, rinse out any debris, and screw it back on.

If a clogged aerator is not the cause, check the cartridge for buildup. This is less common, but sediments can reach the cartridge and obstruct water flow. Turn off the water supply and remove the faucet handle to easily access the cartridge. Once you take out the cartridge and rinse it thoroughly, reinstall it according to the manufacturer’s instructions.

Water Temperature Problems

Another common problem that usually follows DIY faucet replacement projects is inconsistent water temperature. If you run the new faucet and notice that the hot water is cold, or vice versa, the supply lines are likely reversed. This is a simple issue that can be resolved by connecting the supply lines under the sink correctly.

Turn off the water supply, disconnect the hot and cold lines at the shut-off valves, and reconnect them correctly. By ensuring the red line is hot and the blue one is cold, you can restore water flow at the main and test the temperature. If the problem persists despite your efforts, consider hiring a plumbing service provider to inspect and fix the underlying issues.

Noisy Pipes

A knocking or banging sound when turning the faucet on or off usually suggests trapped air in the supply pipes. Also, high water pressure can lead to unusual noises when you run a faucet, prompting an adjustment to prevent further deterioration. When removing trapped air, open the faucets in your house and let the water run for several minutes to flush it out. Once you are certain the system is running as expected, ensure the faucet is mounted securely and not shifting during operation.
