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.

The SAM check valve controls low-head drainage after shutdown within its elevation rating. It does not serve as backflow protection or a pressure regulator.

Why Buy from Big Frog Supply?

Choose 2045ASAM when a Maxi-Paw installation needs both the straight-through impact flow path and a check valve for up to 10 feet of elevation change. Its 3-inch pop-up and full-circle or 20–340-degree pattern help match the turf layout. Select the base 2045A where SAM drainage control is unnecessary, or 2045ASAMNP when the system also requires a purple non-potable identification cover.
