Sprinkler systems are an essential part of keeping your lawn or garden looking its best. But to make sure your system works optimally, you need to know what kind of water pressure is required. For spray heads, the ideal operating pressure is between 30 and 50 pounds per square inch (PSI), with an operating range of 15 to 30 PSI. Drip lines require approximately 20 PSI, with an operating range of 15 to 30 PSI.
The issue is that the operating pressure of most sprinkler systems is determined by the pressure of the water that exists in the main supply line. This usually far surpasses what the system can handle and sometimes exceeds 100 PSI. Leaving too much water pressure unattended will waste water and damage the sprinkler piping, heads, and valves. Because there are many variables that determine how well a sprinkler system works, relying on the advice of an irrigation professional is the best way to guarantee that your system works well for years to come.
Water pressure determines how far apart the sprinkler heads can be to work properly, and it can also decide what type of spray head is the best choice for your application. Low pressures mean that the sprinkler will not be able to irrigate the area it is intended to cover, causing dead spots on the lawn or garden. Your irrigation system can be a big investment; if it doesn't work correctly, your budget and your lawn or garden suffer. The average water pressure for most homes and businesses is between 30 psi and 50 psi; most sprinkler systems are designed to use pressures of around 30 psi. In any case, both systems will have minimum pressure requirements depending on the number of sprinkler heads in the system. To ensure that your sprinkler system works properly, it's important to understand what kind of water pressure is needed for optimal performance.
Knowing this information will help you make sure that your system is set up correctly and that it will last for years to come.
