How to Fix a Noisy Faucet: A Step-by-Step Guide

Whether in the bathroom, kitchen, laundry room, or even outside, a noisy faucet can be more than just a minor annoyance; it can also be a costly waste of water or a sign of underlying issues within your plumbing system.

Many homeowners have found themselves frustratedly searching online for “how to fix a noisy faucet” at some point. Whether it’s a persistent drip, a humming sound, or a sudden loud bang (commonly known as water hammer), understanding the cause and knowing how to address it is crucial.

How Does a Faucet Work?

A typical faucet has two main components: a valve and an aerator. The valve controls the flow of water, while the aerator mixes air with the water to reduce splashing and create a smooth stream.

When you turn on the faucet, water flows through the pipes and comes out of the spout at a specific pressure determined by your home’s water supply. When you turn off the faucet, the valve closes, stopping the flow of water.

Common Causes of Noisy Faucets

There are any number of reasons that a faucet might become noisy over time. Here are a few, along with their faucet noise solutions:

Loose or Worn Washer(s)

One of the most common culprits behind a noisy faucet is a loose or worn washer. When washers wear out or become loose, they can cause vibrations that result in a noticeable noise whenever the faucet is turned on or off.

Solution: 

• Inspect the washer: Turn off the water supply to your faucet and disassemble it to check the condition of the washer.
• Replace the washer: If the washer appears worn or damaged, replace it with a new one of the same size and type. Reassemble the faucet carefully.

High Water Pressure

Excessive water pressure can cause various noises, including humming, whistling, or banging. High water pressure not only affects the faucet but can also lead to more serious plumbing issues if left unaddressed.

Solution: 

• Measure water pressure: Use a water pressure gauge to measure the pressure in your home. Ideal water pressure should be between 40 and 60 psi.
• Install a pressure regulator: If the pressure is too high, consider installing a pressure regulator to bring it within the recommended range.

Water Hammer

Water hammer occurs when the flow of water is suddenly halted, causing a loud banging or thumping noise. This can happen when you quickly turn off a faucet or when an appliance like a washing machine shuts off the water supply.

Solution: 

• Install water hammer arrestors: Water hammer arrestors can absorb the shockwave caused by sudden water stoppage, preventing the noise.
• Check for loose pipes: Ensure pipes are securely fastened to prevent them from moving and causing water hammer.

Loose or Faulty Faucet Parts

Sometimes, the noise can be attributed to loose or faulty parts within the faucet itself. This includes components like the aerator, handle, or cartridge.

Solution: 

• Tighten loose parts: Check all parts of the faucet for any that may be loose and tighten them as necessary.
• Replace faulty components: If any parts are damaged or worn beyond repair, replace them with new ones.

Mineral Deposits

Over time, mineral deposits can build up within the faucet, particularly in areas with hard water. This buildup can restrict water flow and cause noise.

Solution: 

• Clean the faucet: Disassemble the faucet and clean all components thoroughly, using a vinegar solution to dissolve mineral deposits.
• Install a water softener: Consider installing a water softener to reduce mineral buildup in the future.

Preventative Measures

Taking steps to prevent faucet noise can save you time, money, and frustration in the long run. Here are some preventive measures to consider:

Regular Maintenance

Regularly plumbing inspect and maintain your faucets by checking for leaks, worn-out parts, and mineral build-up to catch any issues early on. Also, consider replacing washers and seals as needed to keep your faucets in good working condition.

Use Quality Parts

Always use high-quality parts and components when repairing or replacing faucet parts. This includes choosing durable washers, seals, and fittings to ensure the longevity of your faucet and prevent potential noise issues.

Monitor Water Pressure

Keep an eye on your home’s water pressure and adjust as needed to stay within the recommended range. High water pressure can lead to noisy faucets and put strain on the plumbing system, so regulating the pressure can help prevent these issues.

Address Issues Promptly

Don’t ignore faucet noise. Addressing the issue promptly can prevent more serious plumbing problems down the line. If you notice any unusual sounds or vibrations, investigate and address the cause to avoid further complications and potential damage to your plumbing system.

When to Call a Plumber

While there are relatively straightforward DIY solutions for many common faucet noises, there are situations where it’s best to call a professional plumber. Here are some signs that your noisy faucet repair might be beyond a DIY fix:

• If your faucet is leaking excessively, even after attempting to tighten the parts or replace the washer, it’s best to call a plumbing service. Leaks can indicate a deeper problem within the faucet or plumbing system, and a professional can diagnose and fix the issue to prevent further water damage.
• If you hear water running behind the wall or suspect a leak that’s not readily visible, call a plumber right away. They have the tools and expertise to locate hidden leaks and minimize any damage.
• Some faucet repairs involve replacing the cartridge or valve stem, which can be trickier and require specialized tools. If the solution seems complex or requires disassembling a major portion of the faucet, consider calling a plumber to ensure the job is done correctly and to avoid causing further complications.
• If your faucet problem has already caused water damage to your cabinets, floors, or walls, call a plumber immediately. They can not only address the faucet issue but also assess the water damage and recommend next steps for repair.
• If you’re unfamiliar with plumbing repairs or feel uncomfortable working with tools and fixtures, don’t hesitate to call a plumber. A professional can ensure the job is done safely and effectively, giving you peace of mind.

In addition to the above, consider calling a plumber if:

• You’re unsure about the cause of the noise.
• You’ve tried the DIY fixes without success.
• The noise is accompanied by other plumbing problems, like low water pressure.

By knowing when to seek professional help, you can avoid worsening the problem and potentially save money on repairs in the long run.
