A toilet with a brain? Genius! No, really: Touch-free toilets with FlushIQ technology are smart enough to help prevent overflows, detect potential leaks and offer you a clean, touch-free flush.

What is it?

Think of FlushIQ technology as the sophisticated engine under the hood of a flashy convertible—except the car is a really sleek toilet. The technology is a symphony of sensors that flush and fill the toilet, detect potential leaks and help to prevent overflows. It even communicates to you by means of a tiny light that changes color. Toilets that feature FlushIQ technology are intuitive and totally hands-off.

So, there’s no flusher?

Right. Simply place your hand near the sensor on the tank to flush, so touching the toilet is a thing of the past. Behind the scenes, it’s all science: That sensor opens a valve, and water pressure forces a flush. The sensor is positioned out of the way, so users don’t trigger accidental flushes.

Sensor? Sounds fancy.

It is—and so are the other two sensors. A second sensor monitors the water level in the toilet bowl; if the water rises to a certain point—say, because a teddy bear wanted to go for a swim—the sensor prevents additional flushes, averting an overflow. The light will flash red and blue to tell you there’s a problem, and the no-touch toilet won’t flush until it’s fixed; when Mr. Bear is removed, the toilet automatically resets.

A third sensor watches the water level inside the tank. Over time, all toilet flappers deteriorate, causing water to leak out of the tank; the FlushIQ sensor alerts you with a yellow light if the water level drops, or if the tank doesn’t refill properly. Plus, toilets equipped with FlushIQ technology feature Delta Faucet’s pre-assembled SmartFit tank-to-bowl connection that reduces potential leaks where the two meet. Altogether, it’s heavy protection against messy, costly leaks.

So this can save me money?

It sure can. Typical tank or toilet leaks often go undetected. Even the smallest leak in an old flapper can waste gallons of water by slowly draining your tank. When water leaks from your tank into the bowl, a typical tank will continually refill itself. Delta toilets with FlushIQ technology have a sensor that will detect a drop in the water level in the tank and will not refill the tank. The LED indicator will change to yellow the next time the toilet is flushed, indicating a potential leak.

Even if you never have a leak, toilets with FlushIQ technology are low-flow and labeled with the WaterSense seal, which means they use just 1.28 gallons of water per flush. (Standard toilets use about 2 gallons.) These toilets save water—and could cut more than $110 off your water bill each year.* You can feel good about saving money and the planet by conserving water.

Wait, do I have to plug the toilet in?

Nope. The unit runs on four AA batteries that last about two years (you can also use four C batteries for an estimated five-year life). When power gets low, a red light blinks, and you’ll have about a month to replace the batteries. There’s no hard-wiring involved.

How do you clean the thing?

Touch the sensor for seven seconds, and the toilet enters “sleep mode”—in other words, it won’t flush while you’re scrubbing or letting bowl cleaner work its magic. After 10 minutes, the toilet automatically reactivates. Some models also have a quick-release seat that undocks from the bowl for deep cleaning.

*The EPA estimates that a family of four replacing a home’s older toilets with WaterSense-labeled models will, on average, save more than $110 per year in reduced water utility bills, and over $2,200 during the lifetime of the toilets.
