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.
