Choose Rain Bird 2045A for an in-ground impact sprinkler with a straight-through flow path suited to dirty-water irrigation. This base Maxi-Paw uses a 3-inch pop-up and offers a full circle or a 20–340-degree part-circle pattern. Select the nozzle and check operating pressure for the required reach; choose a SAM model when low-head drainage control is needed.

Compatibility & Installation Notes
Flush the piping before installation. Use PTFE thread-sealing tape on threaded connections; do not put PVC cement or other glue on sprinkler threads.
Match the bottom or side connection and seal the unused inlet. Rain Bird does not recommend side-inlet installation in freezing climates.
For a part-circle pattern, lower the trip pin and set the adjustable stops. Raise the trip pin for full-circle operation. Check the pattern with the zone running.
Select the nozzle for operating pressure, available flow and desired overlap. The full family radius and flow ranges are not the performance of every nozzle setting.
The illustrated Maxi-Paw instructions specify arm-spring position B for the supplied blue nozzle. If changing nozzle size or trajectory, follow the applicable host/nozzle guidance.
Frequently Asked Questions
Does this configuration include a SAM check valve?
No. The base 2045A does not include SAM. Choose a SAM configuration when the design requires low-head drainage control.
What watering pattern can it provide?
It provides a 360-degree full circle or an adjustable 20–340-degree part circle. Set the trip pin and adjustable stops for the intended pattern.
Which nozzle is supplied?
The supplied nozzle is blue #8 with a 23-degree standard trajectory. At 35 psi, the manufacturer charts a 38-foot radius and 3.3 GPM.
Which inlet connections are available?
The body has a combination nominal 1/2- or 3/4-inch female bottom inlet and a nominal 1/2-inch female side inlet. Side-inlet installation is not recommended in freezing climates.
Why Buy from Big Frog Supply?
Choose 2045A when you need the base Maxi-Paw’s impact drive and straight-through flow path for a dirty-water irrigation layout. Its combination 1/2- or 3/4-inch bottom inlet and separate 1/2-inch side inlet help match an existing connection, while the full-circle or 20–340-degree pattern follows the watering boundary. Choose 2045ASAM when the design also requires low-head drainage control.
