Pump Guide - Helps Understand The Fittings You Require

Specifying a pump on an irrigation system will boost available pressures and water flows, allowing larger zones and enabling more thirsty items such as pop up sprinklers to be used, however the pump also needs fittings on the inlet and the outlet to connect it to the water source and ensure that it will run reliably.

In this video, Mike Briley from Access Irrigation talks through the options for surface mounted pumps and also submersible irrigation pumps.

All pumps and fittings are available from Access Irrigation, along with friendly and helpful advice.


Measuring water flow and pressure

Small irrigation systems such as drippers can generally be run off the mains water supply without problems, but as water flows get larger there is the danger that the water supply will not be large enough. In addition, sprinkler systems require a certain pressure to operate. If there is too little flow or pressure then the irrigation system will not work properly.

Installing barbed fittings

Barbed fittings are designed for use with low pressure pipe, such as drip watering systems. The barbed fittings are low cost and can neatly be installed inside the pipe using hot water.

Before fitting barbed connections ensure that the pressures used in the system will be below 4.0 bar (drip systems usually operate at around 1 bar) and are only designed for above-ground installations. Barbed fittings can only be used with soft walled above ground pipe - generally this is soft enough to distort when squeezed hard.
