Save Water & Energy

ECOPOWER harvests energy from water flow to power the electronics—no batteries to change and no external power to run. The 0.5 GPM / 10-sec on-demand cycle uses only 0.08 gallons per use, supporting CEC and CALGreen mandates without sacrificing usability.

Everyday Performance You Can Feel

Water flows only while hands are present, then stops—reducing waste and preventing accidental run-on. Self-adjusting sensor logic in the paired spout provides responsive activation across real-world sink layouts and lighting.

Durable, Low-Upkeep Design

A sealed, below-deck controller keeps critical components protected and out of sight. With no batteries, scheduled power maintenance drops to near zero—ideal for schools, offices, and public venues.

Installer-Friendly Integration

Standard G 1/2 (½? NPSM) interfaces and compact dimensions (~4.19? × 4.44? × 5.81?) simplify placement under tight counters. Add TOTO’s TLM10 (manual) or TLE05701U (thermostatic) mixing valve when hot and cold blending is required.

Sized Right For Tight Vanities

The small footprint makes routing hoses and service loops easier, even in crowded vanities and ADA-height lavs. Keep clearances per the spout/controller rough-in for tool access.

Smart Compatibility

Designed for TOTO ECOPOWER spouts (e.g., Standard/Standard-R, Axiom, Helix families). Confirm the spout’s spec sheet for controller pairing and any accessory requirements before ordering.

Code-Ready Confidence

Engineered to North American plumbing codes with listings for potable water and low-lead content. Conservation compliance (CEC/CALGreen) helps with permit approvals and sustainability targets.
