It’s frustrating to fix a dripping tap only to find it still won’t stop. This is surprisingly common and usually means there’s an underlying issue that wasn’t addressed the first time.
Common reasons a tap still drips
Using the wrong washer or cartridge size is one of the most frequent causes. Even a slightly incorrect fit can prevent a proper seal.
Another common issue is a damaged valve seat inside the tap. If the metal surface the washer presses against is pitted or worn, water can leak through no matter how new the washer is.
In mixer taps, a worn cartridge is often the culprit. Cleaning rarely fixes a damaged cartridge, and replacement is usually required.
Poor reassembly can also cause problems. A misaligned component or trapped debris can leave tiny gaps that allow water to pass.
How to fix it properly
Double-check that all replacement parts are the correct size and type. Clean the tap thoroughly before reassembly and ensure everything is tightened securely, but not overtightened.
If the valve seat is damaged, specialist tools are needed to repair it. In many cases, replacing the tap is the most practical solution.
When to call a plumber
If the tap continues to drip after replacing parts, or if you’re unsure about the condition of the tap itself, a professional inspection will save time and frustration.
