    AI Overview
    High-efficiency toilet tanks (HET) are designed to use 1.28 gallons per flush (GPF) or less, representing a 20% reduction in water usage compared to the 1.6 GPF standard. Many modern high-efficiency options utilize 0.8 to 1.1 GPF, especially in dual-flush or pressure-assisted models. These tanks are often available for OEM/ODM customization, allowing for tailored design, branding, and manufacturing for commercial or residential projects. 
    Key Features & Types 
    • Ultra-High-Efficiency (0.8 GPF): Models like the Niagara Stealth use patented flapperless technology to achieve ultra-low consumption (0.8 GPF), often with whisper-quiet, maintenance-free operation.
    • Dual-Flush Systems: Many HET tanks feature two-button options, typically 0.8 to 1.0 GPF for liquids and 1.28 to 1.6 GPF for solids, maximizing water savings.
    • Pressure-Assisted Tanks: Systems like the American Standard FloWise use pressure to offer powerful flushing with reduced water, such as 1.1 GPF.
    • Concealed/In-Wall Tanks: Designed for wall-hung toilets, these save space and offer a modern look, often with customizable flush actuators. 
    ODM/OEM Customization Options 
    • Branding & Design: Customization options include adding logos, specific color options, and unique dimensions.
    • Production & Material: Suppliers offer high-temperature fired, durable ceramic or high-quality PP materials.
    • Technical Specifications: Customizable flushing mechanisms (top press, pneumatic), and choices between side or bottom water inlets.
    • Manufacturing Capabilities: Large-scale manufacturers can provide high-volume production (e.g., up to 5 million sets per year). 
    Top Manufacturers/Models 
    • Niagara: Known for the Stealth ultra-high-efficiency tank (0.8 GPF).
    • Kohler/American Standard: Offer a variety of 1.28 GPF and 1.6 GPF tanks compatible with their high-efficiency series (e.g., Cimarron, Cadet Pro).
    • Gowlybathroom: Specializes in ODM/OEM wall-hung, concealed, and cistern tanks with dual-flush options. 
    Benefits 
    • Water Savings: Significantly reduces water bills by consuming 20% to over 35% less water than traditional 1.6 GPF toilets.
    • Performance: Modern high-efficiency toilets maintain strong flush performance despite using less water.
    • Sustainability: Often certified by EPA WaterSense, confirming water efficiency.

    What is a common problem with toilet tanks?
    The Toilet Is Constantly Running

    The problem is usually in the fill tank. If the water level in the tank is dropping, check the flapper. If it's not sealing the flush valve opening, water from the tank will leak into the bowl, and the toilet will run constantly to keep the tank filled. Replace the flapper as needed.

    Why do plumbers not like one piece toilets?
    Because the tank and bowl are fused into one solid unit, one-piece toilets are heavier and bulkier to transport. This can make maneuvering the toilet during delivery and installation more difficult, especially in tight spaces or multi-story homes.Jul 1, 2025
