If your water consumption increased significantly and there is no explanation for this increase such as watering the lawn, filling a pool or an increased number of people in your household, you may have a leak. Identifying and fixing leaks will save you money.

Check for toilet leaks – they are the most common

Toilets are the number one source of water leaks inside the home so this is the best place to start a leak detection. Because a toilet leak can waste up to 200 gallons of water per day, it is important to regularly test your toilets and quickly repair any leaks you discover.

To determine if a toilet is leaking, place some dye such as food coloring, Kool-Aid, cola or brewed coffee in the tank of the toilet before you go to bed. Do not flush or use the toilet during the test. If you see any of the color in the bowl of the toilet the next morning, then you know you have a leak that needs to be repaired.

If you discover that you have a toilet leak, make sure the lift chain is free of kinks and that you don't have any mineral buildup around your valves that might prevent them from sealing properly. You can also use the adjustment screw on the overflow pipe to lower the water level in the tank to keep it from flowing into the overflow pipe. Most overflow pipes have a line on the pipe that indicates where the water level needs to be. If the flapper valve or plunger ball isn't properly sealing at the bottom of the toilet, you will also get leaks. Parts are available at your local hardware store to replace these items.

Other common sources of leaks

All water faucets (both inside & outside) 
Water heaters 
Ice makers
