Rain Bird 5004+FCSAMR 4-Inch Full-Circle PRS Rotor

Brand: Rain Bird | SKU: 5004+FCSAMR

Product Overview

Match a dedicated, non-reversing 360-degree full circle layout with the Rain Bird 5004+FCSAMR. This 4-inch pop-up rotor has a PRS stem that targets 45 psi when the supply is sufficient. Plus flow shut-off lets you stop water at the individual head during maintenance, and the SAM check valve limits low-head drainage on sloped zones.

Key Features

• 4-inch pop-up stroke and 3/4-inch female NPT bottom inlet.
• Dedicated non-reversing full circle.
• PRS stem targets 45 psi with sufficient supply.
• Plus flow shut-off at the rotor head.
• SAM check valve reduces low-head drainage.

Common Uses

• Full-circle lawn irrigation where watering is needed in every direction.
• Selecting a pressure-regulated replacement rotor.

Compatibility & Installation Notes

Match the 3/4-inch male NPT supply connection and allow room for the retracted body. Flush the line before fitting the rotor, then select the nozzle for pressure, flow and head spacing.

PRS reduces excessive pressure; it cannot raise a low-pressure supply to 45 psi. Check pressure with the zone operating and allow for losses in the supply piping.

Choose FC only where the sprinkler should water completely around itself. This dedicated full-circle model does not provide an adjustable partial arc.

For Plus flow shut-off, insert a flat-blade screwdriver into the flow shut-off slot and turn clockwise 180 degrees to stop flow; turn counterclockwise 180 degrees to resume. The shut-off slot is separate from the arc adjustment.

SAM reduces low-head drainage after the zone shuts off. It is separate from PRS pressure regulation and is not a backflow-prevention device.

Frequently Asked Questions

Can I adjust this rotor to a partial circle?

No. This FC model provides a dedicated non-reversing 360-degree pattern. Choose a PC model for adjustable part-circle watering.

Does PRS always produce 45 psi?

PRS regulates toward 45 psi when inlet pressure and flow conditions are sufficient. It cannot boost an inadequate supply.

Does it have Plus flow shut-off?

Yes. The Plus feature allows water to be stopped at this head while the rest of the zone operates.

Is SAM included?

Yes. Its SAM check valve limits low-head drainage across up to 7 feet of elevation change.

Why Buy from Big Frog Supply?

Choose 5004+FCSAMR when open turf needs a dedicated full-circle pattern together with pressure regulation and drainage control. Its 45 psi PRS target manages nozzle pressure, while SAM holds back up to 7 feet of low-head drainage. Plus shut-off supports individual-head maintenance. Choose an adjustable PC model when the site has a watering boundary.
