In short, yes. All the information is required for the designers to complete a design in full, so they will not begin if it is not present. We will let you know if we require more information when you have submitted a request.A water pressure measurement is not as crucial for micro irrigation systems. We assume it will be connected to a mains-supplied water source with at least 1 BAR pressure - the minimum required pressure for satisfactory performance of a micro irrigation system. If you have any doubt, speak to our team and they can assist you.
