Streamline Bathroom Visits with the TOTO TET1GB32CP 1.6 GPF ECOPOWER Touchless Toilet Flush Valve (Top Spud, 24″ VB Set)
Upgrade high-traffic restrooms with reliable, battery-free, hands-free flushing. TOTO’s ECOPOWER® sensor valve (MPN TET1GB32CP) uses a hydropower turbine—no batteries or hardwiring—to deliver a consistent 1.6 GPF flush. A self-cleaning piston with a 360° filter helps keep debris from interrupting service, while smart sensing prevents ghost flushes, and a mechanical override ensures operation during maintenance. This model ships as a complete 24″ vacuum breaker set for top-spud bowls in a durable polished chrome finish.

Save Energy & Lower Maintenance
ECOPOWER® uses water flow to charge its sensor—no batteries to replace and no external power to run. With no minimum daily usage requirement, the turbine maintains charge even in variable-traffic restrooms, helping reduce maintenance callouts and downtime.
Everyday Performance You Can Trust
The self-cleaning piston design with a 360° filter helps protect the valve from debris for consistent flushing. A 6-second detection window and adaptive sensor range reduce false triggers and missed activations in real-world conditions.
Durable Materials, Easier Care
A solid bronze valve body under a chrome-plated housing stands up to daily cleaning and commercial use. Tamper-resistant screws and a true mechanical override provide secure, straightforward service access when needed.
Installer-Friendly, Complete VB Set
Ships ready for top-spud bowls with a 24″ vacuum breaker set, angle stop, and spud hardware. Standard exposed rough-in and an adjustable tailpiece simplify swaps and retrofits in existing restrooms.
Sized Right For Tight Spaces
The compact valve body—about 7.0″ × 4.56″ × 3.19″—fits neatly over fixtures and behind shields, with clean lines that work in modern or traditional commercial designs.
Code-Ready Confidence
Designed to meet pressurized flushing device standards (ASSE 1037 / ASME A112.1037 / CSA B125.37) and listed by IAPMO (cUPC), with documentation to support UPC/IPC/NSPC/NPC approvals for plan review. Verify local requirements and fixture pairing before installation.
