Toilets have changed fast, and so have the facts. Here’s a few things every plumber should know when it comes to performance, efficiency, and what’s really happening inside the bowl.
1. Myth: “More water = better flush.”
Truth: Modern engineering wins, not gallons. Today’s 1.28 GPF—and even 0.8 GPF—systems move waste better thanks to smarter trapways and bowl hydraulics. See Niagara’s patented Stealth Technology® for a closer look at a vacuum-assisted flush.
2. Myth: “Low-flow means more clogs.”
Truth: Most clogs come from bad installs, venting issues, or old lines—not the flush volume. High-efficiency toilets today outperform most old 3.5 GPF units.
3. Myth: “A toilet’s flush score tells the whole story.”
Truth: Real performance depends on the entire system—line condition, pipe sizing, venting, and building age all matter.
4. Truth: Rising water rates make efficiency a must.
For property owners, efficient fixtures aren’t just eco-friendly – they directly cut operating costs and reduce stress on aging infrastructure.
Today’s high-efficiency toilets are stronger, smarter, and far more reliable than most customers realize. With the right installs and the right fixtures, plumbers play a huge role in saving water and improving performance.
