# Installation calculators

Try our calculators for a better irrigation system disposition. First, you will need to complete the bucket test below and define your flow rate. This will determine the results you get on the different calculators.

How many sprinklers your system can run at one time depends on how much your home can supply. Your flow rate will determine the total number of pop-up sprinklers you can use at any one time. Different pop-up sprinklers will have their own flow rate. Similarly, drip lines contain emitters which distribute water at a certain rate (typically 2 l/h). The bucket test will also tell you just how much drip line you can run on one zone.

An easy way to calculate your flow rate is by doing a bucket test. All you need is your garden tap, a standard 9 litre bucket and a stopwatch. Before you start, make sure you measure your water flow at times of peak water usage. If using a tap timer or pressure reducer, make sure you measure the flow with the device fitted.
