1. Irrigation using...

RAIN BIRD P5-R Impact Sprinkler
Seaflo pump 12V DC, 5.5 GPM, 60 PSI

2. Sprinkler configuration...

Two sprinklers in series, 24m apart.


3. Illustration...

The sprinkler can be set up to spin 180°, or 360°.
RAIN BIRD P5-R sprinkler is claimed to be capable of reaching 12m in one direction.

That means two sprinklers in series, will cover an area of 48m.


4. Water volume...

The Seaflo pump moves:
5.5 gpm
= 20 liters per minute
= 1,200 liters per hour.


5. Conclusion...

As shown above, two sprinklers on one hose, would cover a circlular area with diameter of 48m. If you run the pump for one hour, that area will get 1,200 liters of water.

You have to decide if that amount of water is too little, too much, or just enough.
Based on the above, you can decide how long to irrigate for.

After one area has been irrigated, the sprinklers can then be moved to irrigate another 48m area.
You can keep doing this throughout the day.

IMPORTANT: The Seaflo pump is not waterproof. So make sure it is not exposed while outside.
