There's no exact number for how many impact sprinklers you can connect to a single water pipe, because it's not determined by the number of sprinklers, but by your home's "water supply capacity."
You can imagine the water pipe as a road, the water flow as cars, and the impact sprinklers as exits. If the road isn't wide enough and there are too many exits, the cars won't be able to move.

Here are some key factors that determine how many sprinklers you can install on a single line:

→ Water pressure

This is the most crucial point. Impact sprinklers work by the force of the water.
Can it handle the load? If you connect too many sprinklers to one pipe, the water will run out of force by the time it reaches the last sprinkler. You'll find that the sprinklers at the beginning rotate freely, while the ones at the end only "drip," unable to rotate at all.
Reduced range: After the water pressure is divided, sprinklers that could originally spray a long distance may now only spray a short distance.

→ Water pipe diameter

The diameter of the water pipe is like the width of the road.
Thicker pipes are more powerful: If you use a thick, professional main pipe, it can supply more water simultaneously.
Thin pipes have limitations: With ordinary household garden hoses, the water pressure will drop significantly after connecting two or three impact sprinklers.

→ The size of the sprinklers themselves

Different impact sprinklers have different water requirements.
Large sprinklers: Sprinklers designed for large farms consume a lot of water, and you might only be able to connect one or two to a single line.
Small sprinklers: If you're using small sprinklers for gardens, you can connect several to one water pipe without a problem.

→ The length of the water flow path

The further the water travels in the pipe, the less force it will have due to friction.
If your water pipe is very long, the pressure will decrease at the end even without any sprinklers connected in between.
Therefore, you can't place impact sprinklers as densely on a very long line as you would on a short one.
