How to Fix a Leaky Faucet

If you're dealing with a persistent dripping and wondering how to fix a leaky faucet, rest assured that many common faucet leaks can be resolved with some simple DIY steps. A leaky faucet not only wastes water but can also be quite annoying. Fortunately, the process of fixing a leaky faucet is usually straightforward and doesn't require extensive plumbing knowledge.

Worn-Out Washers

A worn-out seat washer is a rubber or plastic component that has become degraded due to prolonged use, causing water to leak. This is a common issue in compression-style bathtub faucets, where rubber or plastic washers are susceptible to failure. To fix this issue, a seat wrench can be used to remove the worn-out seat washer and replace it with a new one.

The best course of action for a worn-out washer is simple: replacement. Installing a new washer effectively restores the water-tight seal and stops the leak.

Corroded Valve Seats

The valve seat is an essential component in your faucet that provides the surface against which an intake or exhaust valve rests, helping to maintain a proper seal. Over time, valve seats may become corroded, leading to leaks around the handle.

To address this issue, follow these steps:

  1. Inspect the brass faucet seat with a flashlight for signs of damage.
  2. If you notice corrosion, consider contacting a plumber for inspection and potential replacement.
  3. The plumber may also suggest replacing the entire faucet if other corroded components are found inside.

Faulty Cartridges

In some cases, a faulty cartridge can lead to a dripping faucet due to a compromised seal or worn parts. One way to detect a faulty cartridge is to inspect it for signs of wear and tear, such as cracks, corrosion, or discoloration.

A professional plumber should be contacted if the cartridge is malfunctioning and needs to be replaced. They can inspect and replace the cartridge, ensuring your faucet is working properly once again.

How to Identify Your Bathtub Faucet Type

Knowing your bathtub faucet type is key to its proper repair. There are three main types of bathtub faucets: double-handled, single-handled, and single-lever faucets. Each type has its unique characteristics and repair requirements, including the tub spout.

Determining your faucet type allows you to focus on the specific steps needed to fix the leak, thus streamlining the repair process.

Double-Handled Faucets

Double-handled faucets feature two handles, typically one for hot water and one for cold water, providing more precise control over the flow rate and temperature of the respective water sources.

The primary cause of a dripping double-handled bathtub faucet is often a worn-out rubber washer. Replacing the rubber washers in both the hot and cold valves is the most commonly recommended solution for repairing a double-handled faucet.

Single-Handled Faucets

Single-handled faucets have one handle that regulates both the water flow and temperature. These faucets provide a more streamlined and minimalist design compared to their double-handled counterparts.

In the case of a leak in a single-handled bathtub faucet, it is often the valve cartridge or its rubber O-rings that are worn out or corroded. To repair a single-handled faucet, you will need a brand-specific cartridge replacement.

Single-Lever Faucets

Single-lever faucets:

  • Operate using a ball joint mechanism
  • Feature a single handle or lever to regulate both the water temperature and flow
  • Are easy to install and require drilling only one hole
  • Are a popular choice for kitchens and bathrooms

To repair a single-lever faucet, disassembly and replacement of certain components may be necessary. This may involve replacing worn-out parts, such as O-rings or seals, to restore the faucet’s functionality.
