The total flow rate and pressure you have available at your source will determine this. If you connect your hose to a 34-inch spigot, you typically have a flow rate of 10 gallons per minute. If you had enough pressure at your spigot, you could run two sprinklers at the same time, but you wouldn’t have enough to run one sprinkler at a time.

If you are using a 1/2-in. hose, then you will need to connect the hose to a ½- in. pipe. If you use a 3/4- inch hose and connect it to the pipe, the pressure will only be able to go up to 1.5 psi, which is not enough to start a fire. You will have to add more water to keep the fire going.

## How do I calculate the number of sprinkler heads per zone?

Plants with the same watering needs should be included in each zone. Add up the necessary flow rate in gpm of all the sprinkler heads, divided by the gpm of your water supply. The number will be the same as how many zones you need to add.

For example, if you have a 1,000-GPM supply of water, you’ll need four zones. If you’re using a 2,500-gpm supply, three zones will be needed, and so on.

## How many zones can a sprinkler valve control?

Whether or not your yard has sprinklers, your controller has the capacity for 16 sprinkler system zones. If you have a yard that doesn’t, you’ll need to buy a new controller.

## Can you have different sprinkler heads on one zone?

Don’t mix the type of head because they have different flow rates, because you can mix different brands in the same zone. Water is thrown at a different rate by different heads. If you want to mix head types, you will need to find a way to measure the flow rate of the head.

This can be done by using a flow meter, or by measuring the amount of water that comes out of a nozzle. You can also use a hydrometer, which is a device that measures the pressure inside a container. If you have one of these, make sure that it is calibrated to the specific head type that you are using.

## How long do sprinklers need to run for 1 inch of water?

If you want to know how long you need to water to get one inch, place a plastic container in your yard and set a timer. It will take 30 minutes to get half an inch of water. 20 minutes, three times per week, will give a lawn about an inch of water. It works best with lawns that are well-cultivated.

## Can you hook multiple sprinklers to one hose?

Attach a ‘y’ to your faucet and run a hose to each sprinkler to run more than one sprinkler. Attach a quick- connect to one branch of the ‘Y’ and a hose to the other branch to run 2 sprinklers off the same hose line.
