How to Fix Leaking Taps

Leaking taps may seem like a minor issue, but they can lead to frustrating water wastage and increase your utility bills over time. Fixing a leaking tap is a simple process that can save you money and prevent more serious plumbing issues. In this guide, we'll show you how to identify the cause of a leaking tap and provide clear steps for fixing it. If you're in Sydney and dealing with persistent tap leaks, read on to learn how to solve this common plumbing problem.

Why Taps Leak

A leaking tap typically occurs when water continues to drip from the faucet even when the valve is fully closed. The root cause of this issue is usually related to worn or damaged parts that control water flow, such as washers, seals, or cartridges.

The most common reasons for a tap leak include:

• Worn Out Washers: Over time, washers can wear down due to constant friction against the metal parts inside the tap.
• Damaged O-Rings: The O-ring provides a seal between moving parts. If it's damaged, water can leak from the faucet.
• Loose Parts: Loose parts, especially in compression taps, can cause leaks at the base of the spout or handle.
• Faulty Cartridges: In mixer taps, a faulty cartridge may lead to leaks. These cartridges control water temperature and flow.

Understanding the cause of the leak is the first step toward fixing it. Let's go over some solutions to stop your tap from leaking.

Tools You'll Need

Before starting any plumbing task, gather the following tools:

• Adjustable spanner
• Screwdriver (flathead or Phillips, depending on the screws)
• Replacement washers, O-rings, or cartridges (specific to your tap model)
• Plumber's tape
• Clean cloth

Step-by-Step Guide to Fix a Leaking Tap

1. Turn Off the Water Supply

Before attempting any tap repairs, always ensure the water supply to the tap is turned off. Locate the shut-off valve beneath the sink and turn it clockwise. If you can't find the shut-off valve, you may need to turn off the main water supply for the property.

2. Plug the Sink Drain

It's easy for small parts to slip down the drain during repairs. Use a plug or a cloth to block the drain and prevent any parts from falling in.

3. Disassemble the Tap

To fix the leak, you'll need to access the internal parts of the tap. Depending on the type of tap (compression, mixer, or cartridge), disassembling it may require different steps.

• Compression Taps: These taps typically have separate handles for hot and cold water. Remove the handle by unscrewing it. Then, unscrew the tap bonnet (the decorative cover), and you'll see the valve mechanism.
• Mixer Taps: These have one handle that controls both temperature and flow. You'll likely need to remove the handle and unscrew the cartridge.

4. Inspect and Replace the Faulty Parts

Look for worn-out washers, O-rings, or a damaged cartridge. These are usually the culprits behind the leak.

• Washers: If the rubber washers are cracked, misshapen, or too thin, replace them with new ones of the same size.
• O-rings: If the O-ring appears worn or cracked, replace it with a new one. This small but crucial part helps to prevent leaks around the tap handle.
• Cartridges: For mixer taps, a faulty cartridge can cause persistent leaks. If you notice damage, replace the cartridge with one that matches your tap model.

Make sure to bring the old parts to your local hardware store to get an exact match when purchasing replacements.

5. Reassemble the Tap

Once you've replaced the faulty parts, carefully reassemble the tap by following the reverse steps you used to disassemble it. Be sure not to overtighten any parts as this can cause additional damage.

6. Test the Tap

After reassembling the tap, turn on the water supply and check for leaks. Run the tap for a few minutes to ensure the problem is resolved. If there's still a leak, it could be due to an improperly fitted part, or you might need to replace a different component.

When to Call a Professional Plumber

While fixing a leaking tap is often a simple DIY task, there are instances when professional plumbers help is needed:

• Persistent Leaks: If you've replaced the washers or cartridge but the leak persists, the issue could be more complex.
• Corroded Pipes: Over time, corrosion can cause leaks in the pipes that supply water to your taps. A professional plumber can assess the situation and fix the pipes.
• Lack of Tools or Expertise: If you don't have the right tools or experience, hiring a plumber can prevent further damage and save you time.

Benefits of Fixing Leaking Taps

Save Water: Even a small leak can waste a significant amount of water over time. Fixing leaks helps conserve water, which is especially important in Sydney, where water conservation is a priority.

• Lower Utility Bills: Reducing water wastage means you'll see a decrease in your monthly water bill.
• Avoid Further Damage: Leaks can damage the internal components of your tap, causing more expensive repairs in the future. Addressing the issue early can save you from larger expenses.

Common Mistakes to Avoid

• Using the Wrong Parts: Always ensure you're replacing the faulty parts with the correct ones. Using the wrong size washer or cartridge can lead to further leaks.
• Over-Tightening: Tightening the parts too much can cause the seals to break. Tighten the components just enough to stop any movement.
• Ignoring Drips: Even a small drip can be a sign of a larger issue. Address leaks promptly to prevent further damage.

Fixing a leaking tap doesn't have to be a daunting task. With the right tools, parts, and a little know-how, most homeowners can address this common plumbing issue on their own.
