How to calculate your flow rate

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.

Calculating your flow rate

Place a 9 litre bucket under your garden tap, and turn the tap on full boar. Using a stopwatch, time how long it takes the water to reach capacity. Enter your results in the fields below to calculate your flow rate.

Fittings explained

Confused about the different types of fittings? Let us explain for you to make your next DIY project easier.

Barbed ends

Barbed fittings connect your system. Insert the barbed fitting into the poly pipe or drip tube and secure with a locking clamp.

Threaded ends

For a watertight seal use threaded end fittings. These are common for connecting your water emission devices such as solenoid valve and pop up.

Male fittings

Male fittings feature the thread on the outside of the fittings. Male fittings are paired with female fittings with the same BSP for a watertight connection.

Female fittings

Female fittings feature the thread on the inside of the fittings. Female fittings are paired with male fittings with the same BSP for a watertight connection.

Diameter

The size of your poly pipe, drip tube or pop-up will dictate the fittings you'll need. Refer to the size in millimetres, or BSP for threaded fittings.

Secure your fittings

Prevent poly tubing and Drip Eze® from slipping off barbed fittings by locking them securely in place with either a Loc-Sure® Clamp or Locking Clamp.

Add some height

Rigid Risers screw directly into poly pipe to enable jets and spray to be located above ground.

Redirect water

Use elbows, tees or crosses to direct the water flow around a corner, or joiners to connect additional sections of poly pipe.
