A dripping tap is more than just an annoyance—it can waste significant water over time and lead to higher bills. Thankfully, most dripping taps are easy to fix with basic tools and some know-how. In this guide, we’ll explore the steps required to fix a leaking tap, common issues, preventive measures, and FAQs to help you tackle this problem confidently.
Types of Taps and Their Repair Needs
Different taps use distinct mechanisms, and identifying the type will help in selecting the right repair approach.
Compression Taps
These older taps have separate handles for hot and cold water and usually leak due to worn-out washers.
Cartridge Taps
These taps have a cartridge inside, which regulates water flow. When leaking, the cartridge or O-ring often needs replacing.
Ball Taps
Common in kitchen sinks, these taps use a ball mechanism to control water. They are prone to leaks if internal seals wear down.
Ceramic Disk Taps
Known for durability, they use ceramic plates and rarely leak. If they do, it usually requires replacing the ceramic disks or seals.
Tools You’ll Need
Adjustable wrench
Screwdrivers (flathead and Phillips)
Needle-nose pliers
Replacement parts (washers, O-rings, or cartridges)
Plumber’s grease
Utility knife or small slotted screwdriver
Old cloth or rag (to catch parts and protect surfaces)
Step-by-Step Guide to Fixing a Dripping Tap
Turn Off the Water Supply
Locate the valve under the sink and turn it off. This prevents water from spilling while you work.
Plug the Drain
Cover the sink’s drain with a rag or stopper to avoid losing small parts during disassembly.
Disassemble the Tap
Remove the tap handle by unscrewing the decorative cap and the handle screw beneath it. You may need pliers or a wrench to access the internal components.
Inspect the Parts
Look for damaged washers, O-rings, or cartridges, as these are the most common causes of leaks.
For Compression Taps: Replace the seat washer and O-ring. Coat them with plumber’s grease to ensure a tight seal.
For Cartridge Taps: Remove the cartridge and install a new one. Ensure it matches the old cartridge in size and fit.
For Ball Taps: Replace worn seals or springs inside the ball mechanism.
For Ceramic Disk Taps: Check for cracks in the ceramic plates and replace them if needed.
Reassemble and Test the Tap
After replacing the faulty parts, reassemble the tap by following the disassembly steps in reverse order. Turn on the water supply and test to ensure the drip has stopped.
Common Causes of a Dripping Tap
Worn Washers: Compression taps rely heavily on washers, which degrade over time.
Damaged O-rings: These rings create watertight seals. When cracked, they can cause water to leak around the handle.
Cartridge Wear: Frequent use can degrade cartridges, leading to leaks in modern taps.
Loose Components: Handles and fittings may loosen, allowing water to escape around the spout or base.
Addressing these issues quickly prevents further water wastage and keeps your tap functional.
Preventing Future Leaks
Regular Inspections: Check for signs of wear on washers, O-rings, and cartridges every few months.
Tighten Loose Parts: If handles or spouts become loose, tighten them promptly to prevent leaks.
Use Plumber’s Grease: Applying grease during repairs reduces friction and extends the life of washers and O-rings.
Upgrade Fixtures: If leaks are frequent, consider replacing older taps with modern ceramic disk models for durability.
FAQs
Q: How much water does a dripping tap waste?
A: On average, a dripping tap can waste up to 20 gallons of water per day, adding to both environmental waste and your water bill.
Q: How do I know which part needs replacing?
A: Disassemble the tap and inspect the washers, O-rings, and cartridge. Visible wear, cracks, or degraded material indicate a need for replacement.
Q: Do I need to call a plumber?
A: Most minor leaks can be fixed with basic tools. However, if the leak persists or you are uncomfortable with DIY repairs, calling a professional plumber is advisable.
Q: Can I prevent leaks entirely?
A: While leaks cannot always be avoided, regular maintenance and inspections can significantly reduce their occurrence.
Q: How long do washers and cartridges typically last?
A: Washers can last 1–3 years, depending on water hardness and frequency of use. Cartridges typically last 3–5 years with normal wear.
Q: What’s the best tap type for preventing future leaks?
A: Ceramic disk taps are known for their longevity and low maintenance, making them an excellent choice for long-term use.
In Summary
Fixing a dripping tap is a straightforward task that can save water, reduce bills, and prevent more serious plumbing problems. Identifying the type of tap and the faulty part—whether it’s a washer, O-ring, or cartridge—is the key to successful repairs. Regular maintenance, such as tightening loose components and inspecting for wear, will also help prevent future leaks. If DIY solutions don’t resolve the issue, don’t hesitate to consult a professional plumber to ensure the job is done right.
