As a general rule, rotors and impact sprinklers require at least 30 psi, while spray heads operate best at 30 psi or less. Check the performance chart for the product you wish to use to determine the best operating pressure for your specific application.
THE WATER PRESSURE TO MY SYSTEM HAS
CHANGED SINCE I INSTALLED IT AND NOW MY SPRINKLERS WON'T ROTATE.
WHAT CAN I DO?
Unfortunately, your problem is a familiar one in growing
communities or subdivisions. Some sprinkler system installers
design the system based only on the water flow available at
the time of design, without considering future changes. If
this is the problem, you can try watering very early in the
morning when no one else is using water. If this doesn't work,
you may have to re-pipe the system.
