Revised August 10, 2017 7 Irrigation Plan Requirements
Table 3: Pressure Calculation Worksheet
Complete this form for the most pressure-demanding lateral and submit it with the irrigation
plan.
Pressure Calculation Worksheet
A. Pressure available at point-of-connection _____ psi
B. Pressure loss through the meter - _____ psi
C. Pressure loss through backflow prevention device - _____ psi
D. Pressure loss in mainline pipe from backflow prevention
device to remote control valve - _____ psi
E. Pressure loss through remote control valve - _____ psi
F. Pressure loss in lateral pipe from remote control valve
to most remote sprinkler - _____ psi
G. Elevation change from point-of-connection to most remote
sprinkler (0.43 psi per foot of elevation):
pressure loss - _____ psi
or
pressure gain + _____ psi
H. Miscellaneous losses through other valves, strainers, etc.
(in some cases this will not be applicable) - _____ psi
I. Total possible pressure loss (add B through H) - ___ psi
J. Remaining pressure (subtract I from A) ___ psi
K. Minimum pressure required at sprinkler _____ psi
L. Difference (Subtract K from J. If the value is negative,
a booster pump may be needed. If the value is more than
+15 psi, pressure reduction may be necessary for this
zone, and/or other zones.) ___ psi
