Our Picks: Best Commercial Toilet Flush Valve reviews
1. Sloan Regal 111: A Manual Flushometer for High-Traffic Restrooms
The Sloan Regal 111 is a manual flushometer built for commercial restroom use. It delivers a stated 1.6 gallons per flush and uses a non-hold-open handle, so the flush cycle is not meant to continue just because someone keeps pressing the handle.
The listed configuration includes a sweat solder adapter and cover tube, a cast wall flange, and a screwdriver-operated Bak-Chek angle stop. Its brass castings are described as high-copper and low-zinc for resistance to dezincification. The metal handle is ADA-compliant, an important feature when accessibility is part of the project requirements.
This is a strong option if you want a conventional manual valve from a brand with a broad commercial flushometer lineup. Its 1.6 GPF volume may not suit a project that specifically requires a lower-volume fixture, and you should confirm that the adapter and connection type match your plumbing before ordering.
Pros:
- 1.6 GPF flush volume is clearly specified.
- ADA-compliant, non-hold-open metal handle.
- Includes a sweat solder adapter and cover tube.
- Bak-Chek angle stop allows water shutoff at the valve.
Cons:
- Manual operation is not a fit for buyers seeking touchless flushing.
- Confirm the water connection and toilet compatibility before purchase.
Verdict: Choose the Sloan Regal 111 if you need a conventional 1.6 GPF commercial flushometer with an ADA-compliant handle and the listed solder-adapter setup.
2. Zurn Z6000 Aquaflush: A Manual Valve with Soft-Close Operation
The Zurn Z6000-WS1-YB-YC is an exposed manual closet flush valve with a 1.6 GPF flush volume. Its listed features include a linear-bypass diaphragm designed to resist clogging, plus chemical-resistant gaskets and seals intended to support a longer service life.
Zurn also specifies quiet operation and soft-close technology intended to help eliminate water hammer. The polished chrome finish and cast wall flange give it a familiar exposed-valve appearance. An exposed sweat solder kit is included, so check the connection requirements for your installation rather than assuming it will fit every existing setup.
Compared with the Sloan, the Zurn highlights diaphragm design and soft-close operation, while the Sloan’s product details call out its ADA-compliant handle and included Bak-Chek angle stop. The Zurn listing also notes a three-year warranty. It mentions LEED- and WaterSense-compliant options, but that does not establish that this particular configuration has either certification.
Pros:
- 1.6 GPF flush volume is specified.
- Linear-bypass diaphragm is described as clog-resistant.
- Soft-close technology is intended to reduce water hammer.
- Includes an exposed sweat solder kit and has a stated three-year warranty.
Cons:
- Manual operation may not meet a preference for touchless flushing.
- Verify the exact connection and fixture fit before installation.
Verdict: The Zurn is worth considering if you want a 1.6 GPF manual valve with a clog-resistant diaphragm and soft-close operation.
3. American Standard Selectronic: A Touchless, Battery-Powered Option
The American Standard Selectronic replaces the manual handle with touchless operation. It is designed for flushometer bowls with a 1½-inch exposed top spud, so that measurement is a key compatibility check before you buy.
This piston-type valve comes with a CR-P2 lithium battery installed. The listed battery life is five years. Its DynaClean wiper spring cleans the refill orifice with each flush, a design feature intended to help prevent valve run-on. Touchless activation can be useful in facilities aiming to reduce contact with restroom fixtures, but this model does rely on a battery.
Unlike the Sloan and Zurn options, the Selectronic does not have a stated flush volume in the supplied product details. Check the valve and toilet requirements together, especially if your project has a specific gallons-per-flush target. It is also a more specialized choice than a standard manual valve, so confirm that the fixture and installation are designed for this model.
Pros:
- Touchless operation avoids a manual handle.
- Includes an installed CR-P2 lithium battery.
- DynaClean technology cleans the refill orifice with each flush.
- Specified for bowls with a 1½-inch exposed top spud.
Cons:
- Requires a battery, unlike the water-powered TOTO option.
- The supplied details do not state its flush volume.
Verdict: Consider the Selectronic if touchless operation is a priority and your bowl has the required 1½-inch exposed top spud.
4. TOTO ECOPOWER: A 1.28 GPF Touchless Valve Without Battery Changes
The TOTO ECOPOWER is a touchless flushometer with a stated flush volume of 1.28 GPF. It generates power from running water, so it does not require an external power source or battery replacement. Its programmed timing is designed to prevent ghost flushing, while automatic activation is intended to reduce missed flushes.
The product details specify toilets with a 1½-inch inlet and 12-inch vacuum breaker tubes. Those measurements should be checked against your toilet and existing plumbing before choosing this valve. Its lower stated flush volume sets it apart from the 1.6 GPF Sloan and Zurn models, but the toilet must be compatible with that flush volume.
The listing supplied for this product indicates that it may not currently be available, so check the product page before planning a purchase. Even if it is available, its fit requirements make it less of a universal replacement than the name alone might suggest.
Pros:
- 1.28 GPF flush volume is clearly specified.
- Water-powered operation does not require battery replacement.
- Touchless flushing avoids a manual handle.
- Programmed timing is designed to prevent ghost flushing.
Cons:
- Requires a compatible 1½-inch inlet and 12-inch vacuum breaker tubes.
- The supplied listing indicates availability may be limited or unavailable.
Verdict: Choose the ECOPOWER if its lower flush volume and water-powered touchless design suit your fixture, and verify that the product is available before relying on it for a project.
5. American Standard Ultima: A Manual Valve with a Self-Cleaning Diaphragm
The American Standard Ultima is a manual, diaphragm-type flush valve for flushometer bowls with a 1½-inch exposed top spud. It uses the brand’s DynaClean self-cleaning wiper spring, which cleans the refill orifice during each flush to help prevent the valve from running on.
The valve also uses EvoLast diaphragm material, which the product description identifies as a way to prevent failure. Its ADA-compliant non-hold-open handle is designed to shut off automatically after each flush. These features make the Ultima a practical manual alternative to touchless models when a compatible bowl and handle-operated valve are preferred.
The supplied product details do not state a gallons-per-flush figure, so check the flush volume against your fixture and project requirements. The listing also indicates that availability may be limited or unavailable; confirm the product page before making plans around this model.
Pros:
- DynaClean wiper spring cleans the refill orifice with each flush.
- EvoLast diaphragm material is intended to help prevent failure.
- ADA-compliant non-hold-open handle shuts off automatically.
- Specified for bowls with a 1½-inch exposed top spud.
Cons:
- The supplied details do not specify its flush volume.
- The listing indicates availability may be limited or unavailable.
Verdict: The Ultima is a sensible manual option if its 1½-inch spud requirement matches your bowl and you confirm its flush volume and availability before ordering.
How to Choose a Commercial Toilet Flush Valve
Match the valve to your toilet
Start with the toilet’s specifications, not the valve’s appearance. Check whether the bowl is designed for a flushometer, then confirm its spud size, inlet, and vacuum breaker requirements. For example, the Selectronic and Ultima list a 1½-inch exposed top spud requirement, while the TOTO specifies a 1½-inch inlet and 12-inch vacuum breaker tubes. Do not assume those details are interchangeable.
Confirm the flush volume
Flush volume is measured in gallons per flush, or GPF. The Sloan and Zurn models in this guide specify 1.6 GPF, while the TOTO lists 1.28 GPF. The supplied details do not state a flush volume for either American Standard model. Choose a valve and toilet combination that meets your project’s requirements, and do not treat a lower GPF figure as proof that a valve will work with every bowl.
Decide between manual and touchless operation
Manual valves use a handle, as with the Sloan, Zurn, and Ultima. Touchless models such as the Selectronic and ECOPOWER activate without a manual handle. Consider how the restroom will be used and which operation style makes sense for the facility. Touchless does not automatically mean maintenance-free: the Selectronic uses a battery, while the TOTO is powered by running water.
Review power and maintenance needs
Look at the valve’s moving parts and power source before you buy. The Selectronic includes a CR-P2 battery, and its product details state a five-year battery life. The TOTO generates power from running water and does not require battery replacement. For manual models, compare design features that may affect upkeep, such as the Zurn’s clog-resistant diaphragm or the self-cleaning wiper springs on the American Standard valves.
Check the water connection and included hardware
Installation details can determine whether a valve is a good replacement. The Sloan includes a sweat solder adapter and cover tube, while the Zurn lists an exposed sweat solder kit. The Sloan also specifies a Bak-Chek angle stop. Compare these details with your existing water supply and installation instructions, and consult a qualified plumber if the connection or fixture requirements are unclear.
Consider access and handle requirements
If the restroom must meet accessibility requirements, pay close attention to the handle design and the applicable project rules. The Sloan and Ultima product details identify ADA-compliant handles. Confirm that the specific valve configuration and installation meet the needs of your facility rather than relying on a product feature alone.
Check availability, warranty, and project documentation
Availability can change, so verify the product listing before scheduling work. The Zurn product description states a three-year warranty; warranty terms for other models are not specified in the supplied details. For a commercial installation, confirm the current manufacturer documentation, local requirements, and any applicable water-efficiency standards before placing an order.
Frequently Asked Questions
What is a commercial toilet flush valve?
A commercial flush valve, also called a flushometer, releases a controlled amount of water directly into a compatible toilet bowl. Unlike a typical residential tank toilet, it does not rely on a tank mounted behind the bowl. The valve and bowl must be designed to work together.
Can I replace one brand of flush valve with another?
Sometimes, but brand alone does not determine compatibility. Compare the bowl type, spud size, water connection, vacuum breaker, and flush volume with the replacement valve’s specifications. Check the installation documentation before removing the existing valve.
Are touchless flush valves battery-free?
Not all of them. The American Standard Selectronic model in this guide uses a CR-P2 lithium battery. The TOTO ECOPOWER model generates power from running water and does not require battery replacement.
Which flush valve uses the least water in this guide?
The TOTO ECOPOWER has the lowest stated flush volume here at 1.28 GPF. The listed Sloan and Zurn models are 1.6 GPF. The supplied details do not specify a flush volume for the American Standard Selectronic or Ultima, so check their product documentation before comparing water use.
What does a non-hold-open handle do?
A non-hold-open handle is designed to return after use rather than remain open while someone holds it down. The Sloan and American Standard Ultima product details specify this style of handle. It supports an automatic shutoff after each flush.
What should I check before ordering a replacement valve?
Confirm that your toilet is designed for a flushometer, then check the spud size, inlet, vacuum breaker tube requirements, flush volume, and water-supply connection. Also verify that the included adapter and any required installation hardware match your setup.
Which commercial toilet flush valve is the best overall choice?
The Sloan Regal 111 is the most straightforward pick in this group if you need a 1.6 GPF manual valve with an ADA-compliant handle and the listed sweat solder adapter. If you want touchless operation, compare the battery-powered Selectronic with the water-powered TOTO, paying close attention to fixture fit and flush volume.
Final Recommendation
For a conventional manual installation, the Sloan Regal 111 stands out for its specified 1.6 GPF volume, ADA-compliant non-hold-open handle, and included connection hardware. The Zurn Z6000 is a strong alternative if its soft-close operation and diaphragm design better fit your needs. For touchless flushing, the Selectronic and TOTO ECOPOWER offer different power approaches, but their compatibility requirements matter. Confirm the valve, bowl, and plumbing specifications before ordering any model.
