Zone Calculator is a tool designed to help the installer determine how many heads to install with each irrigation / sprinkler zone.
This is the available Gallons Per Minute that you are using for irrigation for this particular zone. This is generally less than 15 for residential properties.
Main Line SizeExceeding 5 feet per second may result in damage to pipe or components.
Make a selection to determine the type of sprinkler heads you will be using on this zone.
If you are planning to use Hunter products the calculations will be comparable if you select the nozzles by distance
Drip, Bubblers and Xeri Sprays are all covered in this section. You will need to know the GPH (Gallons Per Hour) for the emitters you plan to use. Simply select the option below that matches your rate of flow in GPH. If you are unsure which emitters to choose, here are some popular options/resources.
These calculations will work with all drip manufacturers as long as you choose the correct emitter for the rate of flow.
If installed properly, MP Rotators are the most efficient type of sprinklers available. They are not the answer for all applications, in fact, I only use them in approximately 1 out of 4 systems, but given the right situation, they work very well. They are less durable and more expensive, but on the other hand, they work well along driveways, because they are less likely to leave water spots on vehicles since they apply water in a very accurate pattern.
MP Rotators are listed here in favor of Rain Bird Rotary nozzles because of their durability.
