How to Detect a Water Leak

To detect a water leak, follow this procedure

  1. At the end of your day, ensure that no water is being used in your house (washing machines, dishwashers, sprinklers or toilets being flushed) and record the number on your water meter. 
  2. Do not use any water overnight. (Do not flush toilets.) 
  3. First thing in the morning, check the number on your water meter. 
  4. If the number has changed, then you have a water leak somewhere inside or outside of your house. 
To detect a toilet leak, follow this procedure

Toilet leaks may be easy to repair, but detecting them is a great challenge, especially when they are completely silent. The first indication of a water leak is an increase in your water consumption. Here is a very quick and easy method to detect a toilet leak.

  1. Remove the tank lid of the toilet. 
  2. Drop five drops of food colouring in the toilet tank. If you do not have food colouring, try using Worcestershire sauce or any very dark liquid. 
  3. Replace the toilet lid and wait 30 minutes. 
  4. Survey the toilet bowl. If the water is clear, then there is no leak in your toilet. If the water has changed colour, there is a leak present. 
  5. Repeat the process with all toilets in the house.

Leaks can be extremely wasteful and very costly. Regularly checking taps, pipes and fittings around your property could save water and money. Some leaks are difficult to detect.
