A barely discernible leak from your toilet's cistern is all it takes to lose over 200kL of water a year!
Leaking toilets often go unnoticed, but they are one of the most common water wasters in the home. A slow leak from your toilet's water cistern down into the toilet bowl can lose over 200kL of water in a year if left unchecked.
To check for a leak in your toilet:
- Place a few drops of food dye into your water cistern
- Leave your toilet for 10-15 minutes without flushing.
- If, after that time, you can see the dye in your toilet bowl, you’ll know you have a leak somewhere.
A deteriorating rubber valve in the cistern is one of the most common causes of toilet leakage. To fix it yourself you’ll likely need to fit new washers or install a cistern outlet kit, available at plumbing supply shops. Alternatively, call in your local plumber.
