Why is your toilet "wasting money"?
A leaking toilet is no small problem! You can waste enough water to take several showers a day, especially in areas like Auckland with water restrictions. This is literally flushing money down the drain! Common culprits include:
- A worn and deformed rubber flapper—accounting for 70% of leaks
- The water level in the inlet valve is set too high or a component is damaged
- A misaligned or aged float system
- Scale or corrosion on internal components
How Find the cause of leaks in 10 minutes!
[Money-Saving Diagnosis] Add a few drops of food coloring or ink to your toilet tank and let it sit for 20 minutes. If color appears in the bowl, it means you're wasting thousands of liters of water every day! Don't worry—90% of the time, the problem lies with the rubber water check valve. All it takes is a $15 part and 10 minutes to fix it yourself, saving you $200 in plumber visits!
Four Steps to a Cost-Effective Repair
-
Turn off the water supply and empty the water tank.
→ Locate the water inlet valve at the back of the toilet and tighten it clockwise.
→ Flush the toilet to empty any remaining water and soak up any remaining residue with an old towel. -
Replacing the rubber water check valve (the simplest and most effective repair)
→ Remove the old valve (usually just remove the hook).
→ Take the old valve to Bunnings or Mitre 10 for a replacement.
→ Install the new valve, ensuring a tight seal. -
