When you notice your toilet tap leaking, it’s often due to worn internal components or faulty mechanisms. Understanding these common causes can help you identify when professional help and repair are needed:
Typical leak sources include:
- Worn washers and seals that no longer create a watertight seal
- Faulty float valves that fail to stop water flow when the cistern is full
- Damaged valve seat and spindles are causing taps to drip continuously
- Corroded outlet valves leading to internal cistern leaks
- Loose connections between tap components and water supply lines
A single leaking toilet tap can waste over 9,000 litres of water annually, whilst a faulty toilet cistern can waste more than 60,000 litres. That’s why prompt professional repair isn’t just about stopping the annoying drip—it’s about protecting your water bills and the environment.
