Metron meters (1-1/2" and 2")
Method for Checking for
a Leak
(3/4" and 1" Sensus meters)
 In
order to check water use on your meter, turn off all in-house water
using fixtures and outside irrigation on your property. Open the
water meter cover and record the position of the small red sweep
hand (rate of flow indicator) and all the numbered digits (totalizer
which indicates the cumulative water use). Take another read of the
red sweep hand and the numbered digits in about ten (10) minutes.
If
the position of the red sweep hand and the digits are the same as
that initially recorded, your water system is water tight. If the
meter read has changed, water is going through the meter and into
your system. If no water is being used on the property, water is
being lost due to a leak and/or plumbing problem. At this point
you should estimate the rate of the loss and then check the water
fixtures or waterlines on your property to determine where the water
is being lost. In the event that you are having difficulty locating
the problem, you may wish to contact a plumber.
The District suggests
that you become familiar with reading your water meter. If you do
not know the location of your meter, and would like District Staff
to show you where it is located and how to read it, please contact
the District at (805) 969-2271.
The display on
the meter measures water in hundred cubic feet. The District
bills in hundred cubic feet increments. The hundred cubic
feet numbers are in white and the cubic feet are in black.
Small amounts of water are measured by the black triangle.
How to Determine the Rate of
Loss
(3/4” and 1” Sensus meters)
METHOD
1
Prior to starting, read the meter and record all the numbers. For
example, let’s assume the beginning meter read is 00000,
and the red hand is on 0. Then after the ten (10) minute
waiting period, the meter read is 00001 and the red hand
has rotated one complete revolution. Subtract the two
meter reads in order to determine the amount of water loss. In
the example, one (1) cubic foot flowed through the period in a ten
(10) minute period; 1 ÷ 10 = .1 cubic feet per minute.
Since there are 7.5 gallons in one cubic foot, divide 7.5 gallons
by 10 minutes to determine the rate of flow; 7.5 ÷ 10 = .75
gallons per minute. Then multiply this number by 43,200
(there are 43,200 minutes in a month) in order to determine the
rate of loss for a month; 43,200 x .75
= 32,400 gallons/month.

METHOD 2
Prior to starting, read the
meter and record all the numbers. For example, let’s assume the
beginning meter read is 00000, and the red hand is on 0.
Then after the one (1) minute, the red hand rotates from 0 to 4/10
(this number equals .4 cubic feet). In the example, .4 cubic foot
flowed through the meter in one (1) minute. Since there are 7.5
gallons in one cubic foot, multiply .4 cubic feet x 7.5 gallons to
determine the rate of flow in gallons; .4 x 7.5 = 3.0 gallons per
minute. Then multiply this number by 43,200 in order to
determine the rate of loss for a month;
43,200 x 3 = 129,600 gallons.
