If your water bill is unusually high, you may have a leak. Toilets and water softeners are the first place to check. A leaky toilet can waste thousands of gallons each month. A continuous leak from a 1/8"diameter water stream can waste over 3,000 gallons each month, while a 1/4" stream can waste over 13,000 gallon in a month's time.
Toilets: The flapper is the most common source of problems. To check this, turn the water supply valve off at the toilet and watch the level in the toilet bowl. If the level drops, replace the flapper and clean the flapper seat in the toilet tank. In addition, check the level in the tank. After flushing, the water should shut off when the tank level is about ½ inch to 1 inch below the overflow. If water does not shut off at this level, adjust the float in the toilet's water tank.
Water Softeners: After the softener has regenerated, check to see if water is still running down the drain. If it is, the softener needs to be repaired. Consider turning off and bypassing your softener. Remember, the Water Treatment Plant softens your water for you!
Faucets: Dripping faucets should be repaired or replaced.
Furnace Humidifier: Inspect the humidifier float to make sure that it is shutting off the fill water at the level recommended by the manufacturer. Check your owner's manual for details.
Overnight Leak Check:
IF YOU FIND A LEAK, GET IT FIXED AS SOON AS POSSIBLE!!!
- Locate your water meter inside your house
- Read and record it in the evening when you are done using water for the day. If you have a softener, pick a day that your softener will not be regenerating.
- Read it again the next morning before you use any water. If your meter reading changes overnight when no one was using water, you have a leak.
