Overview

The Rain Bird MANIF21PK is a professional-grade, six-port drip irrigation manifold designed to deliver water precisely where you need it. Each outlet provides a regulated flow of 2.0 gallons per hour, enabling multi-location watering from a single compact unit. It threads into a 1/2" male pipe threaded (MPT) riser and can be paired with Rain Bird RCKIT-1PS to adapt an existing underground sprinkler system for drip irrigation.

Key benefits at a glance

  • Uniform flow across a wide pressure range (15–50 psi) thanks to a pressure-compensating design.
  • Six 1/4" barbed outlets to attach drip tubing and water several locations from one manifold.
  • Self-flushing action and a 150-mesh stainless-steel filter help minimize clogging over time.
  • Durable, UV- and chemical-resistant construction with a color-coded cap for quick identification.
  • Flexible configuration: cap or uncapped outlets and expansion with 1/4" barbed tees to add ports.

How to use

Attach 1/4" distribution tubing to each barbed outlet to direct water to containers, raised beds, garden rows, or potted plants. With six ports, you can water several zones from a single valve while maintaining individual flow rates. If upgrading an existing sprinkler system, consider using RCKIT-1PS (sold separately) to convert to Drip irrigation.

Durability and maintenance

  • Engineered from highly durable materials designed to withstand outdoor sun exposure and chemicals.
  • Includes a 150-mesh stainless-steel filter; a self-flushing action helps keep emitters flowing smoothly.

Customization and expansion

Customize your Drip area with up to six different emission devices. For more ports, add 1/4" barbed tees (sold separately) and extend the network without starting from scratch. The MANIF21PK also features an outlet with cap removed to enable additional operational ports after careful untipping.

Installation tips

Install on a clean, dry riser and ensure all connections are tightly sealed. The 1/2" FPT inlet threads onto a 1/2" MPT riser for a secure fit, and the barbed outlets accommodate a range of drip tubing brands for versatile layouts.

FAQ

Q: How do I install the MANIF21PK with an existing system?

A: Thread onto a 1/2 in MPT riser and connect 1/4 in drip tubing; it can convert underground sprinklers using RCKIT-1PS (sold separately).

Q: What flow can I expect per outlet?

A: Each port delivers 2 GPH with a pressure-compensating design for uniform flow from 15 to 50 psi.
