Why Diaphragm Flushometers Were Invented

1906

Sloan invents the Diaphragm Flushometer

• Replaced overhead tanks
• Relied on water pressure, not gravity
• Used less water and energy

Pioneers: William Elvis Sloan, Chicago, Illinois USA

Today: Most often specified, Largest installed base

Advantages of All Sloan Flushometers

The Sloan Foundry Advantage

• ISO-9001-2015 Certified
• "Magma" modular software optimizes process conditions to ensure structural integrity.
• Laempe Core Shooter Machines for high performance product quality with around-the-clock continuous operation.

High-production facility produces 60,000 pounds of high quality castings per day. (Augusta, Arkansas USA)

Image Description: A computer screen displaying a 3D simulation of a casting process, showing temperature and velocity data overlaid on the object. Text indicates that by adding pick points, one can see the temperature of the metal fronts and their respective velocities, and that metal solidifies below 1840°F.

Advantage - Semi-Red Brass vs Yellow Brass

• High Copper – Low Zinc
• Improved corrosion resistance
• Reduced "Dezincification": Occurs when zinc in the brass alloy dissolves over time

Semi-red brass lasts longer and requires less maintenance.

Material Comparison:

Image Description: Two close-ups of brass fittings. The left shows 'Semi-Red Brass' with a composition of 80% Brass, 8% Zinc, 12% Other. The right shows 'Yellow Brass' with 60% Brass, 35% Zinc, 5% Other. Semi-red brass is noted for improved corrosion resistance and reduced dezincification.

Advantage - Machining, Plating, Assembly, and Testing in Franklin Park, IL, USA

"Our products are made to last, and we take the necessary steps to ensure our products are sustainable throughout the entire duration of their use."

Image Description: Workers performing machining and assembly tasks in a factory. Another image shows racks of finished flushometer components.

Advantage – Non-hold Open Design

The flushometer is unaffected by a user continuing to hold the handle down.

Image Description: A toilet with a flushometer. Diagram illustrating the basic diaphragm function of a flushometer, showing components like the diaphragm, plunger, and relief valve.

Advantage – Common Relief Valves

Color differentiates the stroke and is one of the factors that differentiates Gallons-per-Flush (GPF).

Image Description: Various relief valves and internal parts kits for closets and urinals, color-coded and labeled with part numbers and Gallons-per-Flush (GPF) ratings. A diagram shows the internal components of a flushometer.

Advantage – No External Flush Volume Adjustment

Sloan flushometers are designed to deliver accurate flush volumes throughout their entire lifetime – no adjustment necessary.

Image Description: A close-up of a manual flushometer handle and a component being held. Text emphasizes that Sloan flushometers provide accurate flush volumes without external adjustment.

Advantage – All Sloan Diaphragm Flushometers Can Be Exposed or Concealed

Image Description: A toilet with an exposed flushometer, a urinal with an exposed flushometer, and two different exposed flushometer models.

Advantage – No Planned Obsolescence

All standard units are backwards and forwards compatible:

• Current components fit past and future products
• Parts for Regal/Sloan/Royal models are easily interchangeable
• Valve bodies built before 1964 require an A108 blue filter ring for dual filtered diaphragms
• Most standard flushometers allow for right or left handed installations

Image Description: Two flushometers shown side-by-side, illustrating backwards and forwards compatibility.

How a Diaphragm Flushometer Works

Image Description: A modern restroom with multiple toilets and urinals, featuring Sloan flushometers.

Basic Diaphragm Function

Diagrams: Three stages illustrating the basic diaphragm function of a flushometer. Image: A hand covering a bowl. Graph: Flow Rate over Time.

1. Moving the handle causes pressure relief. The diaphragm flexes up, releasing water into the fixture.

2. Diaphragm controls the flow rate, volume of water, and slow close.

3. Resets quickly for the next flush.

What's the Difference between Regal, Sloan, and Royal?

Image Description: A reflection of hands on a tiled floor, with the question 'What's the Difference between Regal, Sloan, and Royal?'

Product Positioning

• Good: Regal
• Better: Sloan
• Best: Royal

Image Description: Three flushometers labeled 'Good - Regal', 'Better - Sloan', and 'Best - Royal'.

External Differences

Image Description: Three apples of different colors (green, yellow, red) representing external differences.

External Difference - Appearance

Image Description: Top views and line drawings of the caps for Regal, Sloan, and Royal flushometers, showing branding and country of origin.

External Difference - Hex Coupling

Image Description: Flushometers and close-ups of their hex couplings, differentiating between 'Top' Hex Coupling (Regal and Sloan) and 'Bottom' Hex Coupling (Royal). Arrows indicate the coupling location.

External Difference - Spud Flange

Image Description: Flushometers and close-ups of their spud flanges, differentiating between 'Bell' Shaped Flange (Regal and Sloan) and 'Diamond' Shaped Flange (Royal). Arrows indicate the flange location.

External Difference – Control Stop Cap

• Good – Regal: Hex nut
• Better – Sloan: Vandal-resistant locking stop cap
• Best – Royal: Vandal-resistant, threaded, free-spinning stop cap
• Ultimate – Concealed

Image Description: Close-ups of control stop caps for Regal (Hex nut), Sloan (Vandal-resistant locking stop cap), and Royal (Vandal-resistant, threaded, free-spinning stop cap). An 'Ultimate – Concealed' option is also shown.

Internal Differences

Image Description: Images of a 2020 Chevrolet Blazer, 2020 Buick Enclave, and 2020 Cadillac XT6. (Note: These images are not directly relevant to flushometers and are omitted from detailed description.)

Internal Difference – Vacuum Breaker

A vacuum breaker:

• Provides an instantaneous tight-sealing check against back-flow (required).
• Provides the air gap between flush valve and fixture (required).

The V551A is standard on Regal and Sloan models. The V651A is standard on Royal models and includes a "skirt" that is designed to resist high back pressure from the fixture.

Diagram: A flushometer with a vacuum breaker assembly. Text explains the function of a vacuum breaker and differentiates between the V551A (Regal/Sloan) and V651A (Royal) models, noting the Royal's 'skirt' for high back pressure resistance.

Internal Difference – Handle Seal

• Regal: Uses a standard handle seal.
• Sloan and Royal: Use a triple handle seal.

Image Description: Close-ups of handle seals for Regal (standard) and Sloan/Royal (triple handle seal). Diagram: Flushometer handle assembly.

Internal Difference - Regal Diaphragm
