CHAPIN G405 Hose-End Fertilizer Feeder, 1-Pack — mixes dry & soluble fertilizers, 4 spray patterns

Easy to attach to any standard garden hose, the G405 turns household water into a ready-to-spray fertilizer solution without needing to pre-mix powders. Constructed from rustproof, chemical-resistant polymer, it handles common garden fertilizers while offering a large-capacity hopper and simple thumb control for start/stop operation. It’s designed for both homeowners and pros who want fast coverage without extra measuring or separate mixing containers.

How does the G405 mix dry and water-soluble fertilizers automatically?

The G405 feeds water through its hopper so powder or soluble crystals are blended on contact and carried out the nozzle, eliminating the need to dissolve fertilizer beforehand. Flow rate from your hose controls the mixing speed, and internal channels help maintain a steady solution concentration while you spray.

• Large-capacity bottle holds up to one pound of material for longer runs.
• Internal metering paths blend dry or water-soluble formulas as water flows.
• No premixing bowl or measuring required—load and spray.

What spray patterns and controls are available for precise application?

The unit has a four-pattern dial so you can switch between wide coverage and targeted streams depending on the task. A single thumb-control lever makes it effortless to start and stop the flow, giving you better control over application and reducing waste.

• Four selectable spray patterns to match lawns, beds, or spot treatment needs.
• Thumb on/off control for quick pauses without resetting the dial.
• Patterns adjust instantly for transitions between areas and plant types.

Is the G405 durable and safe to use with common garden chemicals?

Chapin built the G405 from chemical-resistant polymer that resists rust and degradation from fertilizer contact, extending the tool’s service life. A built-in anti-siphon feature prevents backflow into your water supply for safer operation near potable sources.

• Rustproof polymer construction resists corrosion and chemical wear.
• Anti-siphon valve prevents backflow to protect your hose water supply.
• Simple assembly and disassembly for cleaning and winter storage.

How do I maintain and troubleshoot the feeder for reliable performance?

Routine rinsing after each use prevents buildup and keeps metering paths clear; periodic inspection of seals and the anti-siphon valve helps avoid leaks. Chapin also provides customer support and parts information if you need replacement components or operating advice.

• Rinse hopper and nozzle thoroughly after each use to prevent clogging.
• Check seals and connections for wear and tighten as needed.
• Contact Chapin customer support for technical assistance and parts.

Who is this for: The CHAPIN G405 is designed for homeowners, landscapers, and small-scale commercial users who need a fast, portable way to apply dry or water-soluble fertilizers without premixing. It’s ideal for routine lawn fertilization, garden bed feeding, spot treatments, and property maintenance where convenience, chemical resistance, and anti-siphon safety are priorities.
