American Standard Ultima 0.5 GPF Urinal Flush Valve
The Ultima Selectronic 0.5 GPF urinal valve features a touchless sensor, a self-cleaning piston, and a water-saving mode during high-use periods. The valve is powered by an 8-year CR-P2 lithium battery and offers programmable sensor adjustments for easy customization. A self-cleaning piston reduces maintenance needs and helps guard against clogs, while a pressure-compensation mechanism maintains consistent flush volume across varying inlet pressures. Ideal for restrooms prioritizing hygiene and water efficiency.
American Standard Ultima 1.6 GPF Touchless Flush Valve
Designed for 1-1/2 inch exposed top spud flushometer bowls, this unit uses an 8-year CR-P2 battery and delivers touchless operation to limit germ spread. The sensor can be programmed for responsiveness and flush duration, providing a practical, hands-free solution for bathrooms that require reliable performance with everyday use. The precision electronics enable hygienic operation without sacrificing reliability.
Zurn AquaFlush Plus Exposed Sensor Valve
The ZER6000PL-HET-CPM AquaFlush Plus valve features a high-efficiency 1.28 GPF flush and a quick-install retrofit design. It is compatible with standard 11-1/2” rough-ins and 1-1/2” top spuds, making it a convenient option for upgrading older installations. The exposed diaphragm design accepts easy maintenance and replacement parts, contributing to long-term reliability in residential restrooms.
American Standard Ultima 6065721.002 Dual-Flush Valve
This dual-flush, 1.28/1.1 GPF valve offers self-cleaning pistons and hygienic, touch-free operation. With no diaphragms to replace and no intricate filter screens to clean, it is designed to deliver reliable performance even with variable water quality. The integrated wiper spring helps maintain a clear refill orifice with every flush, contributing to consistent operation over time.
TECHO Touchless Toilet Flush Kit
The Techo kit provides an easy upgrade path to a hands-free toilet flush. Installation can be completed in roughly 10 minutes for many common toilets. It features an adjustable sensing range and adjustable water output, enabling a tailored flush while saving water. Powered by four AA batteries, the kit offers a balance of simplicity, efficiency, and reliability for residential use.
Buying Guide: Key Purchase Considerations
- Compatibility: Check whether the valve matches your toilet or urinal’s rough-in, spud size, and valve type (piston vs diaphragm). Retrofits should align with standard 11-1/2″ rough-ins and 1-1/2″ spuds where applicable.
- Water savings: Look for adjustable flush volumes (e.g., dual-flush) and sensors with programmable range to maximize efficiency without compromising flush reliability.
- Power source: Battery-powered sensors reduce electrical work and can offer longer life in damp bathroom environments. Some models use long-life CR-P2 batteries; others may use standard AA/AAA kits.
- Maintenance: Self-cleaning pistons or robust valve components reduce routine upkeep and the risk of clogs or leaks. Consider valves with fewer diaphragms or screens that require regular cleaning.
- Hygiene and reliability: Touchless operation reduces germ transmission. Choose sensors with proven response times and consistent flush performance under varying water pressure.
- Installation and upgrades: Some kits are designed for quick DIY upgrades without shutting off water supply. Others may require professional help for optimal seal and wiring.
- Durability and warranty: Look for corrosion-resistant materials, such as chrome finishes or brass components, and check warranty terms for components like sensors and pistons.
- Maintenance access: Quick-access service ports and replaceable parts shorten downtime and simplify future maintenance.
