Hunter Pro-Spray PRS30 Pop-Up with Check Valve – 100 mm

Uneven watering at the bottom of slopes is often caused by water draining out of low points after a zone shuts off.

The Hunter Pro-Spray PRS30 100 mm with check valve combines pressure regulation with built-in drainage protection, helping spray zones shut down cleanly.

This makes it well suited to sloped sites and areas where elevation changes cause pooling or over-watering.

What this is used for

The Hunter Pro-Spray PRS30 100 mm with check valve is a pressure regulated spray body designed to control outlet pressure and prevent low head drainage.

• Spray zones installed on sloping ground
• Areas where lower heads drain after shut-off
• Systems using fixed spray nozzles
• Installations where pressure control and drainage protection are both required

What to check before you buy

• Pressure regulation: PRS30 regulates outlet pressure to 30 PSI (2.1 bar).
• Check valve function: Built-in check valve helps prevent low head drainage after shut-off.
• Pop-up height: 100 mm riser. Confirm it clears turf and finished ground levels.
• Nozzle type: Best suited to fixed spray nozzles. MP Rotators typically require higher regulated pressure.
• Inlet thread: ½" female BSP bottom inlet.

Important note for MP Rotators

MP Rotator nozzles are designed to operate at higher regulated pressure. For MP Rotator zones, a PRS40 spray body is usually the correct choice.
