Flow rate in gallons per minutes (GPM)
Determining Flow Rate: We measure
irrigation system flow in gallons per minute (gpm). What is the maximum flow
rate of your irrigation system in gallons per minute? Please ask your
irrigation specialist or feel free to estimate.
Estimating Flow Rate: To
estimate your flow rate you will need to determine what your largest zone is.
This would be the zone with the most sprinkler heads. Count up the number of
heads in that zone and multiply that number by 3. This is the number you will
use for this section.

Neptune Pumps have a plate on the back
and have to be identified by their part number. PZ31 is an 11 GPD pump and the

LMI Pumps have a plate on the back and
