Uncover The Mystery: Why Is My Hot Water Tap Leaking?

A leaky hot water tap can be a major inconvenience, not to mention a potential waste of water and money. If you’re experiencing this issue, it’s crucial to identify the cause and take appropriate action to resolve it. Here’s a comprehensive guide to help you understand the potential reasons behind a leaking hot water tap and guide you through the necessary steps to fix it.

Common Causes of a Leaking Hot Water Tap

1. Worn-out Washers:
Washers are small, rubber or plastic seals that create a watertight barrier between the tap handle and the valve body. Over time, washers can deteriorate due to wear and tear, leading to leaks.

2. Loose Tap Handle:
The tap handle is connected to the valve stem with a screw. If the screw becomes loose, it can cause the tap handle to wobble, resulting in a leak around the base.

3. Damaged O-Rings:
O-rings are rubber seals that prevent water from leaking between the tap body and the spout. Worn or damaged O-rings can compromise the seal, leading to leaks.

4. Faulty Valve Seat:
The valve seat is the surface where the washer or O-ring rests to create a seal. If the valve seat becomes damaged or worn, it can prevent the washer or O-ring from sealing effectively, resulting in leaks.

5. Corroded Pipes or Fittings:
Corrosion can weaken pipes or fittings, leading to leaks. This is especially common in older plumbing systems or areas with hard water.

6. High Water Pressure:
Excessive water pressure can put stress on the tap and its components, increasing the risk of leaks.

7. Faulty Cartridge:
Some modern taps use cartridges instead of washers or O-rings to control water flow. A malfunctioning cartridge can cause leaks.

Troubleshooting and Repair Guide

1. Inspect the Tap Handle:
Tighten the screw that secures the tap handle to the valve stem. If the handle is still loose, you may need to replace the washer or O-ring beneath it.

2. Replace Worn Washers or O-Rings:
Turn off the water supply and remove the tap handle. Replace the old washer or O-ring with a new one of the same size and material.

3. Repair Damaged Valve Seat:
If the valve seat is damaged, you may need to call a plumber to have it repaired or replaced.

4. Check for Corrosion:
Inspect the pipes and fittings for any signs of corrosion. If corrosion is present, you may need to replace the affected components.

5. Adjust Water Pressure:
If the water pressure is too high, you can install a pressure-reducing valve at the main water supply.

6. Replace Faulty Cartridge:
If the tap has a cartridge, you may need to replace it if it is malfunctioning. This typically requires disassembling the tap and replacing the cartridge with a new one.

When to Call a Plumber

In some cases, it may be necessary to call a plumber to fix a leaking hot water tap. This is especially true if:

• You are unable to identify the cause of the leak.
• You don’t have the tools or experience to make the repairs yourself.
• The leak is severe or is causing damage to your home.

Prevention Tips

To prevent future leaks, consider these tips:

• Regularly inspect your taps and plumbing fixtures for any signs of wear or damage.
• Replace washers and O-rings as needed.
• Keep your plumbing system free of corrosion by using water softeners or corrosion inhibitors.
• Avoid putting excessive force on the tap handles.
