Why Do Bib Cocks Leak?

Before jumping into the repair process, it’s important to understand the reasons behind a leaky bib cock. There are a few common causes of leaks:

1. Worn-out Washer or Seal

Most bib cocks rely on a rubber washer or seal to prevent water from leaking out when the tap is closed. Over time, these washers can become worn out or damaged, leading to leaks.

2. Loose Valve Mechanism

The valve inside the bib cock controls the flow of water. If it becomes loose, water can seep through even when the tap is off.

3. Corrosion

Corrosion from prolonged exposure to water and moisture can cause damage to the bib cock’s components, leading to leaks at various joints.

4. Cracked or Damaged Components

If the bib cock is old or made from inferior materials, parts may crack or break, causing water to escape.

Tools You’ll Need for the Repair

Before you start fixing the leaky bib cock, make sure you have the following tools:

• Adjustable wrench
• Screwdriver (flathead or Phillips depending on the screws)
• Replacement washers or seals (specific to your bib cock model)
• Plumber’s tape (optional, for re-sealing connections)
• Towel or cloth (to catch any excess water)
• Pliers (optional, if needed for tighter fittings)

Step-by-Step Guide to Fixing a Leaky Bib Cock

Step 1: Turn Off the Water Supply

The first and most crucial step is to turn off the water supply to the bib cock. If the tap is connected to a water line, make sure you close the valve supplying water to the tap. This will prevent water from flowing while you’re working on the fixture.

Step 2: Inspect the Bib Cock

Before making any repairs, take a close look at the bib cock to identify where the leak is coming from. Check the handle, valve, and base of the tap for any signs of moisture or drips. Understanding the source of the leak will help you determine which part needs to be replaced.

Step 3: Remove the Handle

Using a screwdriver, remove the screws that hold the handle in place. In most bib cocks, the handle is secured with one or two screws. Once the screws are removed, gently pull the handle off the valve stem.

Step 4: Inspect and Replace the Washer or Seal

With the handle removed, you’ll likely see the valve mechanism, which is where the leak is most often caused by a worn-out washer or seal. The washer is typically located inside the valve assembly, at the bottom of the stem.

1. Remove the Valve Assembly: Use an adjustable wrench to loosen and remove the valve assembly from the bib cock body.

2. Replace the Washer or Seal: Inspect the washer or O-ring and check for signs of wear, cracks, or brittleness. If you find damage, take the old washer to a local hardware store to buy a replacement of the same size.

If your bib cock uses a rubber washer, simply remove the old one and replace it with a new one. If the seal is damaged, replace it with a new O-ring or washer.

3. Reassemble the Valve: After replacing the washer or seal, place the valve assembly back into the bib cock body and tighten it securely.

Step 5: Reassemble the Bib Cock

Once the washer or seal is replaced, reattach the handle by lining it up with the valve stem. Tighten the screws to secure it in place.

If needed, apply plumber’s tape around the threads before reattaching the valve to ensure a tight seal and prevent future leaks.

Step 6: Turn on the Water Supply

Now that the repair is complete, it’s time to turn the water supply back on. Slowly open the tap to check if the leak has been fixed. Run the water for a few minutes to ensure there are no drips or leaks from the valve or handle.

If the leak persists, check the connection points again and ensure the washer or seal has been correctly replaced. You may also want to double-check that the valve was properly tightened.

When to Consider Replacing Your Bib Cock

If you’ve replaced the washer or seal and your bib cock is still leaking, it may be time to consider replacing the entire unit. Over time, old bib cocks can develop issues like corrosion or internal cracks, which can cause leaks that are difficult to fix. In such cases, it may be more cost-effective to replace your old bib cock with a new one.
