A leaking tap (also known as a dripping tap or faucet) is one of the most common household plumbing issues. While it might start as a small annoyance, a tap that won’t stop dripping can waste a surprising amount of water, increase your water bills, and even lead to long-term damage if left untreated.
This guide is designed to help homeowners understand why taps leak, how to fix them, and when it’s best to call a professional plumber. Whether you’re dealing with a slow drip or a steady leak, this article covers everything you need to know.
O-rings are small rubber seals that help prevent water from leaking around the tap handle or base. When an O-ring becomes loose or deteriorates, leaks often appear around the handle rather than from the spout itself.
Locate the isolation valve under the sink or turn off the main water supply to your home. Open the tap briefly to release any remaining water in the line. Plug the drain to prevent small parts from falling in.
Gently pry off any decorative caps to reveal the screw holding the handle in place. Use the appropriate screwdriver or Allen key to remove the handle and access the internal components.
Check for visible signs of wear:
Replace any damaged washers, O-rings, or cartridges with identical parts. Apply a small amount of plumber’s grease to rubber seals before reinstalling them to ensure a proper fit and smoother operation.
If corrosion is minor, cleaning the valve seat may help. Severe corrosion, however, usually requires professional repair.
Reassemble the tap in reverse order, ensuring all parts are seated correctly. Turn the water supply back on slowly and test the tap. Avoid overtightening, as this can damage new components and cause future leaks.
Regular maintenance can help prevent leaks from developing in the first place:
Small preventative steps can extend the life of your taps and reduce the likelihood of leaks.
While many leaking taps can be fixed with basic tools, some situations are best handled by a professional plumber:
A professional plumber for leak detection can diagnose the issue quickly and ensure the repair is safe, durable, and compliant with plumbing standards.
Most mixer taps can be repaired by replacing the internal cartridge, provided the tap body itself is in good condition.
A leaking tap might seem minor, but it’s a problem that shouldn’t be ignored. Left unchecked, it can waste water, increase costs, and cause further plumbing damage. With the right approach, many leaks can be fixed at home, while more complex issues are best left to professionals.
Addressing a leaking tap early keeps your plumbing system efficient, your water bills lower, and your home protected from unnecessary wear and damage.
