How to Read Your Meter and Use It to Measure Leaks
If you have a water meter you can check your plumbing system for undetected leaks by following these easy steps:
- Find your water meter. They’re often located in the front yard near the street.
- Turn off all running water and water-using appliances, and don’t flush the toilet.
- Read the dial and record the reading.
- After 15-20 minutes, recheck the meter.
- If no water has been turned on or used and the reading has changed, a leak is occurring. The rate (gallons per minute) of the leak can be determined by dividing the number of gallons by the elapsed time. (Check all TOILETS for silent leaks by testing them with food coloring. If the leak can’t be found and fixed, you should call a plumber.)
You should read the meter like a car odometer. You should read the meter from left to right and include the last zero on the meter. If the small black/red triangle or star (leak detector) is moving, water is going through your meter. This means that you have something on or you have a leak.
A lot more water comes out of a faucet than we realize…
A tiny drop of water can add up to 15 gallons a day
A steam 1/32nd of an inch loses 25 gallons a day
A steam 1/16th of an inch loses 100 gallons a day
A stream 1/8th of an inch loses 400 gallons a day
A stream 1/4th of an inch loses 1,600 gallons a day
