Quick checks you can do today
1) Water meter test
Turn off all fixtures. If the meter still moves, there is a leak.
2) Toilet dye test
Add dye to the tank. If it appears in the bowl within 10-15 minutes, the flapper is leaking.
3) Under-sink inspection
Check for moisture, rust, or warped cabinet floors.
If the leak is not obvious, a professional inspection saves time and money.
