How to Stop Hot Water Tap from Ruining Your Plumbing System

A dripping hot water tap can be more than just an annoyance. It wastes water, increases your utility bills, and can even lead to damage to your plumbing system. Knowing how to stop a hot water tap can save you money, water, and headaches. This guide will walk you through the common causes of a hot water tap that won’t stop and provide step-by-step instructions on how to fix it.

Understanding the Problem: Why Won’t My Hot Water Tap Stop?

Before you start fixing your hot water tap, it’s important to understand the reason behind the issue. Here are some common culprits:

• Worn-out Washer: The washer is a small rubber or plastic disc that sits inside the tap’s cartridge. It creates a seal to prevent water from flowing when the tap is turned off. Over time, the washer can wear out, crack, or become deformed, leading to leaks.
• Damaged O-Rings: O-rings are small rubber rings that seal the various components within the tap mechanism. If they become damaged or worn, they can cause leaks.
• Clogged Aerator: The aerator is a small screen at the end of the spout that mixes air with water, creating a smooth flow. If it becomes clogged with debris, it can restrict water flow and cause a drip.
• Loose or Broken Parts: Internal parts of the tap, such as the stem, valve seat, or cartridge, can become loose or broken, leading to leaks.
• Corrosion or Mineral Buildup: Over time, mineral deposits from hard water can build up inside the tap, obstructing water flow and causing leaks.
• Faulty Cartridge: The cartridge is the central component of the tap, containing the valve mechanism and other internal parts. If the cartridge itself is faulty, it can cause leaks.

Step-by-Step Guide: How to Stop a Hot Water Tap

Now that you understand the potential causes, let’s dive into the solutions. Here’s a step-by-step guide to fix a hot water tap that won’t stop:
1. Turn Off the Water Supply: Before you start working on the tap, turn off the water supply to the fixture. Locate the shut-off valve under the sink or in the basement. If there’s no shut-off valve, you’ll need to turn off the main water supply to your home.
2. Remove the Aerator: Unscrew the aerator from the end of the spout using a wrench or pliers. Clean it thoroughly with a toothbrush and vinegar to remove any mineral buildup or debris.
3. Inspect the Washer: If the aerator cleaning doesn‘t resolve the issue, you’ll need to access the internal parts of the tap.

• Cartridge Tap: For cartridge taps, you’ll need to remove the cartridge. This usually involves unscrewing a handle screw and pulling out the cartridge. Inspect the washer inside the cartridge for wear or damage. If it’s worn or damaged, replace it with a new one.
• Compression Tap: For compression taps, you’ll need to remove the packing nut, which holds the stem in place. The washer is located under the packing nut. Inspect it for wear and tear and replace it if necessary.

4. Replace O-Rings: If the washer isn‘t the culprit, check the O-rings for damage. Replace any that are worn or cracked.
5. Clean Mineral Deposits: If mineral deposits are causing the problem, you can try cleaning them with a vinegar solution. Soak the tap parts in a vinegar solution for a few hours, then scrub them with a toothbrush.
6. Replace the Cartridge: If the problem persists, the cartridge may be faulty. Replace the cartridge with a new one that matches your tap model.
7. Reassemble the Tap: Once you’ve addressed the underlying problem, reassemble the tap. Make sure all parts are properly tightened and secured.
8. Turn the Water Back On: Slowly turn the water supply back on and check for leaks. If the leak persists, you may need to consult a professional plumber.

Preventive Measures: Keeping Your Hot Water Taps in Top Shape

To prevent leaks and extend the lifespan of your hot water taps, consider these preventive measures:

• Regular Cleaning: Clean your aerators and tap parts regularly to prevent mineral buildup and debris accumulation.
• Use a Water Filter: If you have hard water, installing a water filter can reduce mineral deposits in your plumbing system.
• Avoid Over-Tightening: When tightening nuts and screws, avoid over-tightening them, as this can damage the tap parts.
• Professional Maintenance: Schedule regular professional plumbing inspections to catch any potential issues early on.

What If My Hot Water Tap is Still Leaking?

If you’ve followed these steps and your hot water tap is still leaking, it’s time to call in a professional plumber. They can diagnose the problem accurately and provide a permanent solution.

Beyond the Tap: Understanding Your Plumbing System

While fixing a leaky hot water tap is often a DIY project, it’s important to remember that your plumbing system is a complex network. Understanding the basics of your plumbing system can help you identify and address potential issues before they become major problems.

Time to Turn Off the Drip: A Final Word

A dripping hot water tap can be a nuisance, but with a little knowledge and effort, you can often fix the problem yourself. By following these steps and implementing preventive measures, you can keep your hot water taps functioning smoothly and save yourself a considerable amount of water and money.
