Grohe 32665DC3 Concetto Pull-Down Kitchen Faucet

Grohe 32665DC3 Concetto: SilkMove Ceramic Cartridge

The Grohe Concetto uses SilkMove technology -- a large-diameter (46mm) ceramic disc cartridge that requires less force to operate than standard 35mm cartridges. The result is a single-lever that responds to light touch for temperature and flow adjustment, reducing hand fatigue during high-frequency kitchen use. Grohe rates the SilkMove cartridge for 2 million cycles with no performance change.

EcoJoy Technology

Grohe EcoJoy integrates a flow regulator at the cartridge inlet that maintains consistent 1.75 GPM output regardless of supply pressure fluctuations (20-100 PSI). The regulator also incorporates an air-injection aerator that adds micro-bubbles to the stream, giving the 1.75 GPM flow a volume appearance similar to a 2.5 GPM standard stream. Grohe claims this creates the sensation of higher flow while using less water.

Dual-Spray Pull-Down

The pull-down head offers Stream and Spray modes via a face-mounted button. The 24-inch hose incorporates a GROHE SilkMove retract mechanism -- a weighted hose guide that pulls the head back into the dock with consistent tension rather than relying on a spring. The head body is solid brass with StarLight chrome finish.
