A leaking tap can be more than just a nuisance—it wastes water and increases your utility bills. Often, the cause of a leaky tap is a faulty tap spindle. If you're dealing with a leaking tap spindle, don't fret! Repairing or replacing it is something you can tackle yourself with the right tools and a little know-how. In this blog, we’ll guide you through the process of repairing or replacing a leaking tap spindle like a pro.

What is a Tap Spindle?

Before we dive into repairs, let’s understand what a tap spindle is and why it’s important. The tap spindle, also known as the valve stem, is the part of the tap that controls the flow of water when you turn the handle. When you twist the tap, the spindle moves up or down to open or close the valve, controlling the water flow.

Over time, wear and tear, corrosion, or mineral build-up can damage the spindle, causing it to leak. A leaking spindle can result in water dripping from the spout even when the tap is turned off, wasting water and potentially causing damage to your plumbing.

Signs of a Faulty Tap Spindle

A faulty tap spindle may not always be obvious, but there are a few signs you can look out for:

• Water Drips When the Tap is Off: The most common sign of a leaking tap spindle is water continuing to drip even when the tap handle is fully turned off.
• Hard to Turn: If you find it difficult to turn the tap handle, the spindle may be worn or corroded.
• Strange Noises: A damaged spindle can cause unusual sounds, such as squeaking or rattling, as it moves inside the tap.

If any of these issues sound familiar, it’s time to inspect the spindle and decide whether to repair or replace it.

Tools You’ll Need

Before you begin the repair or replacement, make sure you have the following tools on hand:

• Adjustable wrench or spanner
• Flathead and Phillips screwdrivers
• Penetrating oil (like WD-40)
• Replacement spindle or washer (if needed)
• Cloth or towel (to protect your tap’s finish)
• Plumber’s tape (optional)

Step-by-Step Guide to Repairing a Leaking Tap Spindle

Step 1: Turn Off the Water Supply

The first and most important step is to turn off the water supply to the tap. This will prevent any unwanted water flow while you’re working. Locate the water shut-off valve under the sink or in your main water supply line and turn it off. You may also need to open the tap to relieve any remaining pressure in the pipes.

Step 2: Remove the Tap Handle

To access the tap spindle, you’ll need to remove the tap handle. Start by using a screwdriver to unscrew the handle’s decorative cap (if applicable). Once you’ve removed the cap, use a flathead or Phillips screwdriver to loosen the screw holding the handle in place. After the screw is removed, gently lift off the handle.

Step 3: Loosen the Tap Nut

Next, you need to remove the tap nut, which holds the spindle in place. Use an adjustable wrench to loosen and remove the nut. If the nut is stuck, apply some penetrating oil and let it sit for a few minutes before attempting to loosen it again.

Step 4: Remove the Spindle

Once the nut is removed, you should be able to pull the spindle out of the tap body. Inspect the spindle for signs of damage or corrosion. If the spindle is worn, cracked, or has mineral build-up, it’s time to replace it.

Step 5: Replace the Washer or Spindle (if needed)

In some cases, the issue may be as simple as a worn washer, which can cause a leak. If the washer is damaged, remove it from the spindle and replace it with a new one. You can also replace the entire spindle if it’s too damaged to repair.

If you’re replacing the entire spindle, make sure to buy a new one that matches your tap model. Installing a mismatched spindle can lead to more leaks or difficulties when turning the tap.

Step 6: Reassemble the Tap

After replacing the washer or spindle, it’s time to reassemble the tap. Start by inserting the new spindle into the tap body, ensuring it fits snugly. Then, tighten the tap nut back into place using your adjustable wrench. Be careful not to overtighten, as this could damage the components.

Once the nut is secure, replace the tap handle and tighten the screw that holds it in place.

Step 7: Test the Tap

Turn on the water supply and check the tap for leaks. Turn the tap handle to ensure the water flows smoothly and there are no drips. If you still notice water dripping, it may be necessary to adjust the spindle or check for further issues, such as damaged seals or washers.

When to Replace the Tap Spindle

While repairing a leaking tap spindle is a great DIY solution, there are times when replacement is the better option. If the spindle is severely corroded, cracked, or worn down, a replacement may be necessary. Additionally, if the tap is old and frequently needs repairs, it might be worth considering a complete tap replacement.

Pro Tips for a Successful Repair

• Use Plumber’s Tape: To ensure a tight seal, you can wrap plumber’s tape around the threads of the new spindle before installing it.
• Don’t Over-Tighten: Over-tightening can damage the components of the tap, so be gentle when reassembling.
• Clean the Tap Body: Take the opportunity to clean any mineral build-up or debris inside the tap body before installing the new spindle.
• Know When to Call a Pro: If you’re unsure about your ability to complete the repair, or if you encounter problems during the process, don’t hesitate to call a professional plumber for assistance.

Conclusion

A leaking tap spindle doesn’t have to be a major issue. With the right tools and a little patience, you can easily repair or replace the spindle yourself and restore your tap to full working order. Whether you're fixing a minor leak or replacing a worn-out component, this guide will help you get the job done like a pro. If you’re ever in doubt, it’s always wise to consult a professional plumber to ensure your repair is done correctly.
