How to Fix a Leaking Tap: Step-by-Step Guide

Ah, the perennial issue of a leaky tap! So, why does it drip? Often, it’s that sneaky little washer, tucked inside, worn and weary, that’s given up its duty of halting the water flow. Or, perhaps, it’s the O-ring, now damaged and letting water sneak past, especially around the base of the spout.

Now, addressing that annoying drip the moment you spot it? That’s sage advice. Let that leak linger and, before you know it, you’re grappling with unsightly stains, safety hazards, and a blow to your health. And consider this: even those seemingly insignificant drips could rob you of 15 litres of water in just a month. Overlooking tap repairs? Think again.

How do you fix a leaking tap?

Despite advances in tap technology over recent years, addressing typical tapware troubles remains straightforward. Armed with a bit of knowledge and the right tools, any seasoned DIY enthusiast can tackle that pesky dripping tap.

Be it a subtle trickle or a more pronounced leak, your first task is to pinpoint the culprit. It might be soaring water pressure, some slack components, or even pipe predicaments. Identifying the problem up front can save you heaps of time and effort, ensuring you apply the most effective fix.

Ready your tools

1. A trusty adjustable wrench (or spanner) – that’s for those stubborn packing nuts.
2. Your flat-head screwdriver – a must-have for yanking out those screws.
3. On standby, the heroes of the day: O-rings, washers, or maybe even a cartridge.
4. Rags paired with white vinegar? Oh yes, for a swift swipe and to battle that nasty grime accumulation.
5. Don’t forget the plumber’s grease or Teflon tape. Essential for smooth operations and safeguarding those faucet components.

Different types of leaks

Some faucet leaks are easy to identify—like when water drips from the spout even with the handle off. But not all leaks are so apparent, and they might happen in areas other than just the spout.

If you notice an unusual increase in your household’s water use, it might be due to less conspicuous faucet leaks. There are three typical locations where these leaks occur.

Leaks Under the Sink

Leaks beneath the sink, often overlooked due to their hidden location, can be highly damaging as the water seeps onto the floor or further down, leading to potential expensive repairs.

To identify the source:

1. Clear out the vanity and dry everything.
2. Run some water and observe for drips.
3. Key culprits are typically:
4. Loose water supply connections.
5. Loose sink drain or P-trap connections.
6. If the source isn’t evident, lay dry paper towels below and check after a day for water marks.

Examine the water supply lines at three junctions:

• Connection to shut-off valves.
• Connection of valves to flexible supply tubes.
• Where tubes link with the faucet tailpieces.
• Leaks often arise from these points and may require tightening or, in worn-out cases, replacing components.

While less frequent, an aged faucet might be the issue, especially if its tailpieces are corroded. Tightening might not suffice, necessitating a replacement.

Lastly, if the leak originates from the sink drain or P-trap fittings, tightening is typically the fix. However, on older sinks, the entire drain fitting might need replacement.

Leaks Around the Base of the Faucet

Leaks around the faucet base may go unnoticed due to frequent water splashes in that area. However, consistent puddles suggest a leak, evident only when the faucet is on. To verify, dry the sink and turn the water on, observing any seepage around the faucet’s base.

Often, this leak results from a worn or cracked internal O-ring, sealing the faucet body. If unresolved by replacing the O-ring, a damaged inner cartridge might be the culprit, requiring its replacement.

Leaks From the Spout

Visible faucet leaks occur when it drips or runs despite the handles being off. You might find the need to adjust the handle more tightly or position it correctly to prevent drips. Such leaks not only increase your water bill but can stain the sink over time.

Initially, such drips may be sporadic. To detect them, dry the sink, place a dry paper towel beneath the spout, and check later for wetness. Alternatively, use a cup or bowl.

The repair depends on the faucet type. For compression faucets, which feel like they’re screwing down onto a washer, the fix typically involves replacing the washer. However, many modern faucets use cartridges, so you’d need to replace the cartridge. Given the frequent maintenance of compression faucets and their gradual replacement by cartridge models, if you own the former, consider upgrading to a newer version.

Conclusion

A leaking tap, while a common household challenge, can be effectively addressed with the right knowledge and tools. By understanding the various types of faucet leaks and their underlying causes, homeowners can tackle the issue head-on, preventing water wastage and potential damage. From identifying the problem, gathering the right tools, to following a step-by-step repair guide, fixing a leaky tap becomes a manageable task. However, if uncertainty persists or the problem seems beyond a DIY fix, it’s wise to consult a professional emergency plumber. Always prioritize the proper maintenance of your tapware, as it not only saves water and money but also ensures the longevity of your faucets.
