Questions
What should I do if my toilet won't stop running?
First, try adjusting or replacing the float in the cistern. If that doesn't work, it could be a faulty flush valve, requiring professional repair. Turning off the water supply at the isolating valve can limit water waste until a tradesperson arrives.
Why is my toilet flush weak?
A weak flush can result from a partial blockage or scale in the cistern or flush valve. Cleaning the components or adjusting the water level in the cistern might resolve the issue. Consult a professional if the problem persists.
How can I prevent toilet leaks at the base?
Ensure the pan connector is properly fitted and in good condition. Regularly check for signs of wear. Tightening bolts and sealing around the base with appropriate materials can also help prevent leaks.
When is toilet replacement necessary?
Replacement is often considered when repairs become frequent, the pan is cracked, or efficiency is compromised even after repairs. Consult a tradesperson to determine if replacement is the best option for long-term reliability.
