A leaking flush valve in your toilet will allow a very slow flow of water to pass from the tank to the bowl and down the drain. Often the only sympton of this issue is the fill valve opening for a few seconds periodically. Although this won’t cause any damage to your home it will waste a massive amount of clean water. Testing for a leaking flush valve is quite simple.
- Die the water in your toilet tank with 2-5 drops of food colouring.
- Wait for 10-30 minutes.
- Inspect toilet bowl for any sign of died water.
- If you find died water in your toilet bowl, your flush valve is leaking.
NOTE: Red or blue food colouring works the best.
NOTE: Existing stains or buildup in a toilet bowl may become tinted from the food coloring.
