locateyourmeterWhat do you need?

  • A screwdriver or shovel to open the lid.
  • A damp cloth or paper towel to clean the meter face.
  • Gloves if there are insects in the box. 

Where is it?

  • For most homes, the meter box will be flush with the ground near the sidewalk or street at the front of your property.
  • Look for a gray or brown lid with a black circle on one end. 
  • If you cannot find it, check under rock mulch or overgrown plants near the edge of the property.
  • CAUTION: If you see bees making their home in the meter box, contact Gilbert Meter Services at 480-503-6800.Gilbert Box

How to read the numbers?

  • Once opened, your meter will look like one of the ones below. Most homes have one of the two in the bottom right.
  • Look on your utility bill to see what size meter you have. Residential customers in Gilbert typically have a ¾ inch or a 1 inch sized meter.

Sensus meterOn  these 3/4 and 1 inch Sensus meters the thousand gallon increments are the number in black with the white background. The next two digits in white with the black backgrounds are the hundreds and the tens increments. The last digit does not turn and the dial with the red pointer records ten gallons for every revolution. The numbers on the red dial each equal 1 gallon. If the black triangle is moving there is water moving through the meter.

leakindicator1

For the 3/4 and 1 inch size Invensys meters they will record down to the tenth of a gallon increments starting from the right side of the digits. The increments go up from there just like the odometer on a car.

leakindicator3

For the 1 inch Metron meter the black numbers with the white backgrounds are still the one thousand gallon increments but now the last three digits do not turn. On this meter the red dial on the right measures one thousand gallons for every revolution. The center red dial reads one hundred gallons for every revolution and the red dial on the left reads ten gallons for every revolution.

Metron Meter

If you have a 3/4 inch Metron meter the black numbers with the white backgrounds are the thousand gallon increments. The white number with the black background is the one hundred gallon increments and the last two digits do not turn. The red dial on the right counts for 100 gallons every revolution. The center red dial measures 10 gallons for every revolution and the red dial on the left measures one gallon for every revolution.

iperl

The new 3/4 and 1 inch iPerl meters have digital displays. The thousand gallon increments are shown with the black dashes above the numbers on the left side of the display. There is a small decimal point between the third and second digits from the right hand side. This means the digit on the far right side of the display equals 1/100th of a gallon. If this digit is counting up then there is a small amount of water moving through the meter.

 Sensus 1 inch

These 3/4 and 1 inch Sensus meters they will record down to the tenth of a gallon increments starting from the right side of the digits. The increments go up from there just like the odometer on a car. The red dial with a black line in it is the leak indicator dial. One revolution of the leak indicator dial is equal to one tenth (1/10th) of a gallon.

 

 

How to check for leaks

After you find and determine what type of meter you have, you can easily check for a leak. On the Sensus meter, the small black triangle located above the numbers is the leak indicator. On the Sensus meter, the leak indicators will move in a clockwise motion when water is being used. On the Invensys meter, the red pointer is what is referred to as the leak indicator. On the Metron meter, the red asterisk is the leak indicator. This will move in a counter clockwise direction when water is being used. On the Iperl meter, the circle with a + in it indicates water is moving through the meter.

With all the water turned off in the house, there should be no movement of the pointers or the dials on any of the meters. If you have turned off all the taps in the house, and the meter appears to be turning, you may have a leak. Find how to identify leaks here.  Use the step-by-step Smart Home Water Guide to isolate the leak and determine where it is coming from. 

What do I do if I can’t find the leak?

Before calling in a plumber you can schedule a free water efficiency checkup with a Gilbert Water Conservation Specialist. You can also call the Water Conservation office at 480-503-6098 to schedule an appointment.

What do I do if the meter tells me I don’t have a leak but my water use is still high?

Still schedule a Water Efficiency Checkup with a Gilbert Water Conservation Specialist. We will go through all the water using fixtures of the house, including the irrigation system, and almost always come up with the answer to the question of “where is all my water going?” For additional assistance – Water.Conservation@gilbertaz.gov
