Underground sprinkler systems make it simple to water your yard and keep it green. Knowing the number of sprinkler heads that every valve can manage ensures the setup is suitable for adequate coverage. Each valve covers a zone. The number of sprinkler heads in each zone is determined depending on the water pressure available.
Assess Pressure
Check the water pressure in your home utilizing a water-pressure gauge on the outside tap for the sprinkler system. Make sure there is not any water running any place in the home before assessing the pressure to find an accurate reading. The needle gauge lets you know the pounds per square inch, or psi.
Faucet Output
Calculate the gallons per second to your tap by measuring the time it requires the tap to fill out a 5-gallon bucket. Divide the time measured by five to determine the gallons per second, or GPM. This will inform you how much water every valve zone can manage for optimum output.
Sprinkler Heads
Calculate the number of sprinkler heads for a valve zone by dividing the GPM from the sprinklers’ mind outputsignal, which can be recorded on the packaging. Round down the number so that you don’t exceed the capacity of the zone. Sprinkler heads change in water output depending if they supply a mist spray or stream of water.
