How to Fix a Dripping Tap: A Step-by-Step Guide
A dripping tap can be more than just an annoyance—it can also waste water and increase your bills. Whether it’s a slow and steady drip or a fast leak, the problem can usually be solved with a few tools and some basic DIY skills. In this blog, we’ll walk you through how to fix a dripping tap step by step.
Common Causes of a Dripping Tap
Before diving into the repair process, it’s helpful to understand why taps leak in the first place. Here are some common causes:
- Worn-out washer or O-ring: The most common cause of a dripping tap. These small rubber parts can wear out over time, causing water to leak.
- Damaged valve seat: Over time, the valve seat, where the tap connects to the spout, can corrode or become damaged, leading to leaks.
- Loose or damaged tap parts: If any part of the tap assembly becomes loose or damaged, it can cause water to drip.
- Water pressure issues: Sometimes, uneven water pressure can cause the tap to drip intermittently.
Tools You’ll Need
To fix a dripping tap, you’ll need the following tools:
- Adjustable spanner (wrench)
- Screwdriver (flathead and Phillips)
- Replacement washer or O-ring (specific to your tap model)
- Plumber’s tape (optional)
- Allen key (for mixer taps)
- Cloth or rag (to protect the tap from scratches)
Step-by-Step Guide to Fixing a Dripping Tap
Follow these steps to fix your dripping tap:
Step 1: Turn Off the Water Supply
Before starting any repair, it’s crucial to turn off the water supply to the tap to avoid any accidental flooding. Locate the isolation valve (usually found under the sink) and turn it clockwise to stop the water flow. Open the tap to let any remaining water drain out.
Step 2: Plug the Sink
This simple step will prevent small parts, such as screws or washers, from falling down the drain while you’re working on the tap.
Step 3: Remove the Tap Handle
Use a screwdriver to remove the cap or decorative cover on the top of the tap handle, revealing the screw underneath. Unscrew it and gently remove the tap handle. If the tap handle is stuck, a cloth or rag can help you get a better grip.
Step 4: Loosen and Remove the Tap Bonnet
Next, use an adjustable spanner to loosen and remove the tap bonnet (the top part of the tap). Once removed, you will expose the internal components of the tap, such as the valve and washer.
Step 5: Inspect the Washer or O-Ring
Check the condition of the washer or O-ring at the base of the valve. If it’s worn, cracked, or damaged, this is likely the cause of the leak.
Step 6: Replace the Washer or O-Ring
Take the damaged washer or O-ring to your local hardware store and get an identical replacement. Once you have the correct part, fit the new washer or O-ring into place. If you’re dealing with a ceramic disc tap, this step may involve replacing the entire cartridge.
Step 7: Reassemble the Tap
Once the new washer or O-ring is in place, reassemble the tap by reversing the steps. Screw the tap bonnet back into position, reattach the handle, and secure it with the screw.
Step 8: Turn the Water Supply Back On
After reassembling the tap, turn the water supply back on by reopening the isolation valve. Slowly open the tap to check if the dripping has stopped and to make sure everything is working properly.
Preventing Future Drips
Fixing the tap is only part of the solution. To avoid future issues, consider these tips:
- Regular maintenance: Periodically check your taps for any wear and tear, and replace parts as needed.
- Use the tap gently: Avoid over-tightening the tap when turning it off, as this can wear down the washer or O-ring more quickly.
- Monitor water pressure: High water pressure can contribute to leaking taps. If you notice issues with pressure, consult a plumber for advice.
When to Call a Professional
While fixing a dripping tap is a straightforward DIY task in most cases, there are situations when it’s best to call in a professional. For example:
