Irrigation pressure: how to achieve a perfect irrigation system

When it comes to irrigation pressure, balance is everything. Pressure and flow rate are the two key elements that determine whether your system is working optimally or not. Understanding how to measure and adjust them correctly is the first step towards precise, efficient and waste-free irrigation.

Pressure and flow rate in irrigation: what they are and how they are related

Pressure is the force with which water is pushed through the system, while flow rate indicates the amount of water that flows in a given time (usually litres per minute).
If the pressure is too low, the water will not reach all parts of the system; if it is too high, it can cause waste or damage to components.

A well-balanced system finds its perfect rhythm: the right pressure and ideal flow rate ensure that each sprinkler distributes water evenly and without waste.

How to measure pressure and flow rate in irrigation

To find out the actual values of your system, i.e. how pressure and flow rate behave, you need two simple but indispensable tools:

• A pressure gauge to measure water pressure.
• A bucket and stopwatch to estimate the flow rate: simply fill a graduated container and calculate how many litres per minute the water point delivers.

This data will help you see if the system is working properly or if it needs to be adjusted.

What happens if the pressure of the irrigation system is incorrect

Excessive pressure can cause uneven spraying, leaks and even damage to solenoid valves or fittings.
Conversely, insufficient pressure results in uneven distribution: some areas receive too much water, while others remain dry.

Both situations reduce the efficiency of the system and increase water consumption, so it is essential to keep the values within the recommended range for the different types of sprinklers.

How to adjust and balance the irrigation system

There are various tools and solutions for optimally managing irrigation pressure:

• Pressure reducers: ideal for stabilising flow and protecting the system.
• Specific controllers: such as Zero Pressure, designed to deliver water even at minimum flow and pressure values.
• Control and programming systems: these allow the system to be divided into zones, adapting pressure and flow rate.

By combining these tools, you can achieve a balanced, high-performance system with uniform irrigation and water savings.

An efficient irrigation system starts with the right pressure

Taking care of your irrigation pressure is like giving your system new energy: it keeps it in shape, efficient and ready to perform at its best. A few periodic checks are all it takes to prevent breakdowns and ensure top performance, season after season.
