When you're first setting up any watering system, you'll need to know how much water is available from your tap (or water source). The flow rate (and pressure) will dictate how many sprinklers, sprayers or drippers you can run at any given time.
It's important to know your pressure and flow, as you'll need to work within the water that's available when you have a watering set up which needs more water than you have available, then you'll see reduced performance (or no performance - such as pop ups dribbling or not popping up).
This can be worked out with a flow test, using a pressure gauge test kit and/or a simple bucket test. The Bucket Test can be measured by timing how long it takes to fill a household bucket (any bucket which has volume markers - 9l/12l etc).
Our DIY flow rate test can be found here:
Flow Rate Test DIY with Bucket - Holman Industries
Please note: If you plan on adding a tap timer to automate your watering, do the bucket test with the timer in place; the timer will reduce your flow rate so this needs to be taken into account before choosing sprinklers.
Once you know how much water is available, then you can get planning. Let's say we had 20L per minute (20LPM) available.
Flow rates (and spray radius) for our sprinklers can be found on their product pages (and physical labels), which will help with your next steps.
50mm Pop up Sprinkler Full Circle - Holman Industries
Using the example of 20L per minute (LPM), and a 360 degree pop up:
The 360 degree states a flow of around 9LPM
180 degree @4.5LPM
90 degree @ 2.5LPM
In this case, you can run 2 pop up sprinklers with our 360 degree pattern, 4 of the 180 degree, 8 of the 90 degree or any combination of these; within the 20L available.
