Professor Toilet 101

Hello, my name is Professor Toilet. Welcome to my online classroom. I am here to help you learn about the toilet and the science behind how it works. In Flushology, the syllabus is simple. The content here will help you understand:

1. The science (hydraulics) behind a really good flush.
2. The greening of toilet flushing
3. How to fix problems when the laws of physics are over-ruled by a poorly engineered toilet that results in clogging, leaking, ghost flushing and other stress-inducing symptoms.

Browse the site, educate yourself and happy flushing.

    Champion 4 Toilet Delivers Happy Customers–No Callbacks–for Dunbar Plumbing

    Dunbar Plumbing, a leader plumber in northern Kentucky, cites “simple design and powerful flushing action,” as reasons why the Champion 4 Toilet is one of Dunbar’s best selling flushers.   Below is their own video showing the amount of water in the bowl and exclusive Accelerator Flush Valve inside the tank:

    In their own words, on their forum, Dunbar Plumbing explains the benefits of the Champion 4 toilet:

    With the American Standard Champion 4 toilet, our customers have been extremely pleased with the flushing action of the toilet with a “no worry” attitude about what possibly gets thrown down the toilet. This toilet uses a small fraction of water compared to the older 1.6 gallon toilets including the 3.5 gallon flush toilets. Now that these new style toilets use so little water compared to the wasteful 3.5 gallon toilet, it’s a no brainer that those older toilets were such a costly design. We’ve watched the advancements in the technology grow over the past 25 years and it has been a road hard paved with good intentions to finally get a good working, good flushing toilet.”  Read more at the Dunbar Plumbing Forum.

    WikiAnswers – Are Toto or American Standard toilets better?

    Doral Classic Champion 4

    Doral Classic Champion 4

    The Professor is a fierce but fair competitor.  As a toilet scientist, third party testing data from Maximum Performance Testing (MaP testing) is most compelling in choosing a new toilet.  In those tests, the Champion 4 toilet reigns supreme.

    Nonetheless, user feedback is important.  As such, Professor Toilet offers up a variety of opinions via commentators at WikiAnswers – Are Toto or American Standard toilets better.  If you have an opinion about American Standard toilets vs. our competitors, talk back to the Professor and tell you story.

    Champion 4 Toilet Named an Innovative Way to Take the Grunt Work out of Home Maintenance – MSN Real Estate

    The Professor is mightily humbled.

    MSN Real Estate chose only one toilet in a recent feature profiling innovative products that make housework and home maintenance easier.

    Calling the Champion 4 a “low-maintenance, plunger-free toilet,” the editors at MSN note that it “dispatches 70% more material than usual in each flush thanks to a 4-inch flush valve.”  MSN also cites our exclusive EverClean surface that inhibits the growth of mold, mildew and the bacteria causing toilet stains and smells.

    Dual Flush Toilets – Why Jetted is Better

    The Professor has a handful of hot dogs to prove that a siphonic dual flush toilet is better than a washdown dual flush.

    How can just 0.9 gallons of water flush 5 large hot dogs?   Because H2Option is the first  truly siphonic dual flush toilet, with strong push and pull action created by forceful but quiet jetted action under the rim.

    Bathroom Blogfest 09: Flush this economy, but do it with science

    This post is part of Bathroom Blogfest 09. Professor Toilet is proud to be one of 21 bloggers invited to participate in this third annual event, celebrating all aspects of bathrooms. This year’s Bathroom Blogfest theme is “Flush the Recession and Plunge Into Forgotten Spaces.”

    The Science Behind a Really Good Flush

    American Standard Brands Jim McHale, Ph.D.

    American Standard Brands Jim McHale

    Jim McHale, Ph.D. is one of toilet scientists behind Professor Toilet.  Or a Toilet Technologist, as Science Careers magazine named him in a profile.

    Why would Science Careers profile a guy who makes toilets?  Toilets are a high tech appliance, something people don’t really appreciate until faced with a toilet repair or clogged toilet.

    Toilet science includes:

    Physics, governing water distribution to effectively clean the bowl and prevent clogged toilets.

    Mechanical and Materials Engineering, governing the operation and reliability of the valves for flushing toilets.

    Chemistry, to understand the properties of clay, glazes, plastics and increasingly, antimicrobial surfaces on toilets.

    Biology, to understand and control the sanitary properties of toilets and slow bacterial growth.

    Geometry to guide the toilet designs and aesthetic innovations, while statistically analyzing every elementto ensure reliable function.

    Watch Jim explain the science behind water saving dual flush toilets.

    Professor Toilet appreciates being part of Bathroom Blogfest 09. ( In fact, The Professor appreciates now knowing what a blogfest actually is.  The Professor has never pretended to be hip to social media. )

    How to Measure a Toilet Rough In

    Toilet rough in measuring: from wall to bolt cap.

    Toilet rough in measuring: from wall to bolt cap.

    When talking toilets, the toilet rough in is the distance from the wall behind the toilet to the center of the outlet pipe where the waste leaves the toilet. The most common distance is 12 inches, so most toilets have a “12-inch rough.”

    In some cases, the outlet is closer to or further away from the wall, especially in older homes.  For those cases, toilets are available with a 10-inch rough or 14-inch rough.

    Before replacing a toilet, measure the rough in or make sure your plumber measures before buying.

    To measure accurately, measure from the wall–NOT the molding–to the bolt caps. (Note: The Professor sincerely apologizes for the ugly wallpaper.)

    How a Toilet Siphon Works

    To understanding how a toilet siphon works, think about a train going over a mountain.

    As American Standard Chinaware Director James Walsh explains in this video, once a train crests the mountaintop, it heads downhill, pulling the rest of the train with it.

    In a toilet, the flushing action pushes water and waste up the s-shaped trapway, until it crests at the top, the part known as the weir.  The water then rushes downhill, creating a pull that scours waste and paper from the side of the bowl and out the trapway.
