Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone’s lines or a leak at a nozzle or two. Leaking nozzles won’t produce the same water pressure and need to be replaced, which is fairly simple.
What causes low pressure in one zone of sprinklers?
If the pressure is low at only one or two sprinkler heads, they may simply be dirty. Examine the sprinkler head and filter and clean if needed. Grass can also grow around the base of the sprinkler heads and cause them not to pop up fully, so trim and clear away any obstructions.

How do you increase gpm on a sprinkler system?
If you pump your own water from a well, stream, or pond the only way to increase your water flow is to install a newer and/or larger pump, larger pipe leading to and from it, and possibly drill a deeper well. You will need to see the Irrigation Pumping Systems Tutorial for details on how to do that.
How much water pressure is needed for a sprinkler system?
around 30 psi
How is pressure measured? Water pressure is measured in pounds per square inch – also called psi. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi.
Can I use different sprinkler heads on one zone?
Never put different types of irrigation heads on the same irrigation zone to operate at the same time. The precipitation and/or application rates of the nozzles and emitters of the rotor, spray, bubbler, drip, micro-irrigation, etc. are entirely different.
Can you combine sprinkler zones?
Running multiple zones at once is usually not possible due water-pressure and flow limitations at residential properties. As with any standard irrigation controller, you can wire multiple solenoids/valves to the same zone output if you want.
How often should you replace sprinkler heads?
Annual inspections help ensure the system is working correctly, and no rust or water back-up has occurred. Even with regular maintenance, sprinkler heads do not last forever. Fire safety protocol recommends you get sprinkler heads replaced once every five years to prevent fire sprinkler leaks.
