Automatic flush valves use a sensor to flush a toilet or urinal without touching a handle. Electronic Faucet sells hands-free flush valves and sensor flush valves for commercial and residential restrooms, with solid brass construction, 20+ finishes, battery-powered models, and retrofit valves that replace most Sloan, Zurn and Toto toilet flush valves.

Automatic Flush Valves for Modern Bathrooms

Give your bathrooms a big upgrade. Visit Electronic Faucet to check out our automatic flush valves. Why is touchless flushing such a big deal for modern bathrooms now? They offer great accuracy and make things easier. Going touch-free boosts cleanliness fast, and it helps limit the spread of germs. Our automatic toilet flush valves work great in busy offices or right at home. They mix smart tech with all-brass construction built for lasting service.

At Electronic Faucet, we care a lot about your setup. That is why we focus on reliable gear that is easy to maintain, with a spec sheet and an installation manual on every product page. Our smart bathroom tools take the headache out of regular restroom maintenance. A replacement battery pack is available, and the ATV-2B retrofit replaces most Sloan, Zurn and Toto toilet flush valves. Whether you are fixing up a busy commercial space or updating a guest bathroom at home, you will find the setup you need.

Hands-Free Flush Valve System

Let us talk about the Hands-Free Flush Valve system. This is a neat electronic flush valve with a solid brass piston-type valve. It replaces old, clunky flush systems and gives a more accurate amount of water to the bowl every time. It is easy to use: the built-in sensor starts the flush, so there is nothing to push, and the exact amount of water needed is released.

How does the sensor hold up in a busy public restroom?

The sensor and electronics are hermetically sealed, so they are protected inside the unit, and a built-in particle strainer helps the valve last longer. A visible low battery indicator in the sensor capsule tells you when to change the batteries, and a manual flush button works independently of the battery and electronics, so the toilet can still be flushed if the batteries run out.

Benefits of automatic flush valves

Each flush uses a set amount of water, which brings great consistency. Toilet models are available at 1.28 or 1.6 gallons per flush, and the AUV-2 urinal flush valve ranges from 1.0 down to 0.125 gallons per flush, so you can match the valve to your water goals. Hands-free operation also means there is no handle to reach, press or grip. The clean, touchless design keeps things more sanitary, which makes it a practical choice for public restrooms and packed business spaces.

How Do You Choose an Automatic Flush Valve?

Choosing an automatic Electronic Flushing System is simple once you know your fixture. Here is what to check before you buy:

  1. Fixture: a toilet valve (ATV-2) or a urinal valve (AUV-2).
  2. New installation or replacement: use a complete unit for new work, or the ATV-2B retrofit to replace most Sloan, Zurn or Toto toilet valves.
  3. Flush rate: toilet valves are 1.28 or 1.6 gallons per flush, and urinal valves range from 1.0 to 0.125 gallons per flush.
  4. Power: these valves run on four AA batteries, with a low battery indicator and a manual flush button as a backup.
  5. Finish: 20+ finishes match MAC Faucets and soap dispensers, so the whole sink and toilet area can share one look. See our finishes page and matching pair collection.
  6. Code: Check ADA requirements and your local plumbing and accessibility code before you install.

Frequently Asked Questions

Where do I find a hands-free flush valve for my California toilet?

Electronic Faucet sells hands-free flush valves for toilets and urinals and ships to California. The ATV-2 is a battery-powered automatic toilet flush valve, and the AUV-2 is the urinal version. Both are complete units that include the stop valve, spud, coupling and flashings. If you are replacing an existing Sloan, Zurn or Toto valve, the ATV-2B retrofit is made for that.

What automatic flush valve do California plumbers most commonly install?

Plumbers can choose between a complete unit, the ATV-2 for toilets or the AUV-2 for urinals, and the ATV-2B retrofit for replacing an existing valve. Every product page has a spec sheet and an installation manual, so a plumber can check the fit before the job. The ATV-2 fits any commercial toilet installed in the US and Canada.

I am planning a restroom upgrade for my California hotel. What touchless toilet flush options are available?

For a hotel, the ATV-2 gives you a touchless toilet flush valve in 20+ finishes that match MAC Faucets and soap dispensers, so the whole bathroom can share one finish. If you are replacing existing valves, the ATV-2B retrofit replaces most Sloan, Zurn and Toto toilet flush valves. Each valve has a manual flush button that works independent of the battery, which keeps a toilet usable if the batteries run out.

independently Are there ADA-compliant sensor flush valves in California?

The ADA allows flush controls to be hand operated or automatic, and an automatic sensor valve is the automatic option, so sensor flush valves suit accessible restrooms. Whether a restroom complies also depends on the installation and on local code, and California has its own accessibility rules, so confirm the requirements for your project. We ship to California.

hand-operated Is a hardwired flush valve worth the extra installation cost over a battery model for a California airport?

Our current automatic flush valves, the ATV-2, AUV-2 and the retrofit models, are battery powered, so installation needs no electrical wiring. A visible low battery indicator is built into the sensor capsule, so batteries can be changed before they run out, and a replacement battery pack is available. For a busy location such as an airport, build battery checks into regular maintenance, and contact us if your project needs a different power setup.

battery-powered Where can I buy a commercial toilet sensor valve rated for continuous public use in California?

For a commercial restroom, look for durable construction and easy service. The ATV-2 is made for commercial and residential applications, with a solid brass body and piston-type valve, a built-in particle strainer and hermetically sealed sensor electronics. It is manufactured in accordance with applicable unified plumbing codes. Contact us if you would like help choosing a valve for a high-traffic project.

Does an ADA flush valve installed in a California public restroom need to be touchless, or just easy to operate?

Touchless is not required. The ADA says flush controls must be hand-operated or automatic, and hand-operated controls must be usable with one hand without tight grasping, pinching or twisting. California sets a lower maximum height of 44 inches for hand-operated controls. An automatic sensor valve meets the automatic option, and the manual flush button on our valves is a backup. Check your local code before you finalise the installation.

Can I replace my Sloan, Zurn or Toto flush valve with an automatic one?

Often, yes. The ATV-2B retrofit flush valve replaces most Sloan, Zurn and Toto toilet flush valves. Check the installation manual and spec sheet on the product page against your current valve before ordering.

How much water does an automatic flush valve use?

It depends on the model you choose. The ATV-2 and ATV-2B toilet valves are available at 1.28 or 1.6 gallons per flush, and the AUV-2 urinal valve is available at 1.0, 0.5, 0.25 or 0.125 gallons per flush.

What happens if the battery in an automatic flush valve runs out?

Each valve has a visible low battery indicator built into the sensor capsule, so you can change the batteries before they run out. If they do run out, the manual flush button works independent of the battery and electronics. A replacement battery pack of four AA batteries is available for the ATV-2 and AUV-2.
