How much water pressure is needed for irrigation?

Determining your specific pressure is necessary to your irrigation plan. Keep in mind that sprinkler and drip systems will not work properly if the pressure is too low or too high. Most sprinkler systems work at an optimal pressure of 30-50 psi, and most drip systems work best in the range of 20-40 psi.

Thereof, how many zones do I need for my sprinkler system?

The resulting number will equal how many zones you need. If, for example, each sprinkler head will require a flow rate of 1.31 GPM and you have 20 of them, then you will need 26.2 GPM total. If your system can only handle 16.67, you will need to use two zones to cover that same area of your yard.

What pressure is needed for drip irrigation?

A typical drip irrigation system needs about 25 pounds per square inch (psi) of water pressure to function optimally, but many emitters rated at 25 psi will work well at pressures as low as 15 psi.

Do you need a pressure regulator for drip irrigation?

Most drip systems operate best at lower water pressures than are common in a typical water supply system. You probably will need to install a pressure regulator on your drip system if your water pressure is higher than 2,8 bars (40 PSI). Keep in mind that a pressure regulator only reduces the water pressure.
