Brand: K-Rain SKU: 6605
Product Overview
The K-Rain 6605 is a six-outlet 6000 Series distributing valve configured for five-zone operation. Its factory-installed cam advances water through five selected outlets as the upstream source cycles off and on, leaving one of the six physical outlets outside the sequence.
This model is intended for higher-capacity irrigation and distribution systems using pumps or high-flow city water. The valve top and housing use die-cast metal, while the six-outlet lower section is high-strength ABS polymer. A 1½-inch female NPT inlet feeds six 1½-inch slip outlets. K-Rain lists operation from 15 to 150 GPM and 25 to 150 PSI, making the valve suitable for larger residential, commercial, and approved wastewater or effluent applications.
The built-in atmospheric vacuum breaker helps the valve drain and reset when flow stops. Five-zone indexing still depends on correct vertical installation, adequate flow, proper off-cycle timing, and outlet laterals that do not create extreme hydraulic imbalance. The integrated vacuum breaker should not be assumed to satisfy every backflow-protection requirement.

Compatibility and Installation Notes
Identify the five active outlets before piping. Install vertically, use approved thread sealant and solvent cement, and allow water flow to stop completely between cycles. Confirm that the supply, valve, and piping can provide the selected zone flow at the required dynamic pressure.
Frequently Asked Questions
Why are there six outlets for five zones?
The five-zone cam leaves one physical outlet outside the operating rotation.
Can the valve be changed to six zones?
Yes. Install the compatible P8002906 six-zone cam and connect the unused outlet.
Are the outlets 1 inch like some 4000 Series valves?
No. The 6000 Series outlets are sized for 1½-inch PVC connections.
Why Buy the K-Rain 6605 from Big Frog Supply?
The 6605 delivers the five-zone sequence in K-Rain's higher-flow six-outlet platform without requiring a separate cam purchase. Big Frog Supply also carries the six-zone cam, valve housings, seals, stem assemblies, and vacuum-breaker components for future service.
