Rain Bird RD04SP30NP 4-Inch SAM 30 PSI Spray Body — Non-Potable

Brand: Rain Bird | SKU: RD04SP30NP

Product Overview

Match a non-potable spray zone that needs 30 psi pressure regulation and low-head drainage protection with Rain Bird RD04SP30NP. This 4-inch RD1800 body includes the SAM check valve and purple non-potable identification. It is the SAM/PRS version without the Flow-Shield option, and its nozzle is selected separately.

Key Features

• Triple-Blade Wiper Seal balances flushing and debris protection.
• Debris pockets help keep grit from recirculating inside the body.
• Reinforced ratchet ring supports nozzle-pattern alignment.
• Top-access internal components simplify service.
• Built-in 30 psi pressure regulator.
• SAM check valve helps prevent low-head drainage across elevation changes up to 14 feet.
• Purple non-potable identification with “DO NOT DRINK / NO BEBA” warnings and symbol.

Common Uses

• Non-potable spray-nozzle layouts requiring regulated pressure and drainage protection.
• Replacing a matching RD1800 body after checking pop-up height, features and inlet fit.

Compatibility & Installation Notes

Check finished grade, the 6-inch body height and the 4-inch pop-up stroke. Connect through the bottom inlet; the SAM check valve relies on that bottom connection.

Measure operating pressure and confirm the supply supports the 30 psi nozzle target and combined zone demand. A regulator cannot boost inadequate supply pressure.

Choose a compatible Rain Bird nozzle and filter screen, flush before nozzling and align the pattern using the stem ratchet. Follow the selected nozzle’s own radius and arc instructions.

The SAM check valve limits drainage after shutdown; it does not close a leaking upstream control valve.

Frequently Asked Questions

Does it include a nozzle?

No. Choose a compatible nozzle and the required screen separately for the desired arc, reach and flow.

Does this model include Flow-Shield?

No. RD04SP30NP includes SAM and 30 psi regulation without Flow-Shield. Choose RD04SP30FN when that service-indication feature is needed.

Can I use a side inlet?

No. This SAM model requires its 1/2-inch female NPT bottom inlet.

Will its regulator increase low supply pressure?

No. The regulator reduces available pressure. The technical specification gives a 35–100 psi inlet range for the 30 psi regulation target; check pressure while the zone operates.

Why Buy from Big Frog Supply?

Choose RD04SP30NP when the job calls for a purple-marked non-potable body with 30 psi regulation and SAM protection for up to 14 feet of elevation head. Its 4-inch stroke, 6-inch body and bottom-only inlet help check replacement fit. Choose the separate RD04SP30FN when a missing-nozzle service-indication stream is also required.
