# Quick Answer: How Is Water Flow Available Through A Supply Line Measured In Homeowner Irrigation Systems?

## How is water pressure normally measured in homeowner irrigation systems?

Water pressure is measured in pounds per square inch – also called psi. You can measure the water pressure at your site with a flow meter or water gauge attached to an outdoor faucet. When determining your sprinkler needs, use the lowest pressure reading to ensure the best functionality.

## How do you measure water flow at home?

Here is how to measure your water flow rate Take the amount of water in the jug in litres (e.g. 0.8 litres) and multiply this by 10. This will give you your flow rate in litres per minute (e.g. 0.8 litres x 10 = 8 litres per minute).

## How do I find my mains water flow rate?

The easiest way to get a fairly accurate measure of your water flow rate is to time yourself filling up a bucket. So for example if you fill up a 10 litre bucket in 1.5 minutes, then your flow rate will be: 10/1.5 = 6.66 Litres per minute.

## How many sprinkler heads can I put on one zone?

At different pressures, the sprinkler head and nozzle will consume different amounts of water. For example, at 35 pounds per square inch (PSI) the 5000 Series Rotor using the 3.0 nozzle will use 3.11 gallons per minute (GPM). If your home’s water capacity was 10 GPM, you could place 3 heads per zone.

## How many PSI do I need to run my sprinklers?

The optimum operating pressure for most residential sprinkler heads is between 30 and 50 pounds per square inch (PSI). With correct water pressure, each head will perform the way they were designed, and the result will be even spray-patterns and efficient use of water.
