CHAPIN G405 Fertilizer Feeder Hose-End Sprayer, 1 lb Hopper, 4 Spray Patterns & Anti-Siphon

The CHAPIN G405 Fertilizer Feeder is a hose-end sprayer that automatically mixes dry and water-soluble fertilizers and delivers them through four selectable spray patterns with thumb control.

Designed for homeowners and professionals, this hose-end feeder attaches to any standard garden hose and combines convenience with durable, chemical-resistant construction. Its generous hopper holds up to one pound of dry or water-soluble fertilizer so you can treat lawns, gardens, and landscape beds without pre-mixing. Built-in anti-siphon protection and a 4-pattern dial make it simple to switch from targeted spot treatments to broad coverage while preventing unintended backflow into your water supply.

How does the G405 mix dry fertilizer without pre-mixing?

The feeder uses the flow of water through the unit to dissolve and distribute granules or water-soluble materials on demand. As water passes the hopper, it draws fertilizer into the stream and disperses a consistent solution based on hose flow and the material used.

• Large hopper holds up to one pound of dry or soluble fertilizer
• Automatic dissolution while the water flows—no jar or premixing required
• Even distribution for continuous coverage during application

What spray patterns and controls are available for different tasks?

The G405 features a four-pattern dial so you can choose the right spray for the job, plus an easy thumb on/off control for quick starts and stops. Patterns range from narrow streams for targeted spot treatments to wide sprays for covering larger turf and garden areas.

• Four distinct spray patterns selected with a twist dial
• Thumb-operated on/off control for immediate flow control
• Pattern choices support spot treatment, edging, and broad lawn coverage

Is the feeder safe for my water supply and built to last?

The unit includes an anti-siphon feature that prevents fertilizer solution from being drawn back into your hose and municipal supply, addressing common safety concerns. Its polymer construction resists rust and typical garden chemicals for reliable seasonal use.

• Integrated anti-siphon prevents backflow into the water line
• Chemical-resistant, rustproof polymer housing for durability
• Simple maintenance—rinse after use to prolong life

How easy is it to set up and maintain the CHAPIN G405?

Setup is straightforward: attach the G405 to any standard hose end, add fertilizer to the hopper, and select a spray pattern. After use, flush the unit with clean water to remove residual fertilizer and store in a dry place between seasons.

• Quick attach to any standard garden hose—no tools required
• Hopper fills and empties easily for fast refills and clean-out
• Rinse interior after each use to avoid clogging and buildup
