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.

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.

Water Conservation Put to the Test in Metro Atlanta
No one loves tests as much as professors. And no one loves a test of toilets more than Professor Toilet.
Especially when test results reveal a high grade of satisfaction when it comes to toilets, faucets and showerheads that save water.
American Standard identified 21 homeowners in two suburban Atlanta communities who volunteered to replace their existing toilets and bathroom sink faucets last fall with high-efficiency WaterSense®-certified models, and to replace their showerheads with the highly-rated FloWise showerhead that delivers an invigorating, satisfying soak while reducing water usage up to 40 percent.
After two months of measurement, green building consultant Tommy Linstoth, LEED-AP found an overall household savings of at least 25 percent. The level of satisfaction has been higher than expected. American Standard has not received a single request to return to the higher-consumption products and several volunteers reported that the products exceeded their expectations, as well as the performance of their previous higher-consumption products. Learn more at Tommy’s RehydrateUS.org blog.
Below, Tommy explains the purpose of the test:

WikiAnswers – Are Toto or American Standard toilets better?
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.

Green Lodging News ~ Torn in Two About the Benefits & Challenges of Dual Flush Toilets
Followers of Professor Toilet know that dual flush toilets can be a mixed blessing. On one hand, dual flush toilets can save both water and money.
Glenn Hasek of Green Lodging News, notes the downside to some models regarding the small area of water in the bowl also known as the water spot:
“…some dual flush toilets do not clean the bowl as efficiently as traditional single-flush versions. Be sure to ask vendors about this. Without getting into too much detail here, you obviously do not want to leave your guests with a bad impression and you do not want to add to the work load of your housekeepers.”
Hasek echoes what the Professor has said before about dual flush toilets. “Dual flush toilets that use a siphonic design have a water spot the size found in standard toilets.“ Learn more from Toilet Scientist Jim McHale and follow Hasek’s blog at Green Lodging News:

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.

Read Any Good Water Bills Lately?
If water conservation is the goal, do you know how to read your water bill?

In today’s lesson, Tommy Linstroth, founder of RehydrateUS.org, helps demystify the water bills from the City of Atlanta. Linstroth is consulting with American Standard on a water efficiency test for two Georgia neighborhoods.
Most bills have a fee for water use and sewer use, both of which are based on how much water comes through the meter at your house. Utilities typically assume that the same amount of water coming into your house (your water bill) is the same amount leaving in the sewer (your sewer bill). Thus the two fees are directly related.
Water is often billed in a unit of hundreds of cubic feet, shown as CCF. One CCF (or hundred cubic feet) = 748 gallons of water.
Unfortunately, by measuring in such large units, there’s not that sense of satisfaction Americans are used to in seeing numbers going down, such as reducing a grocery bill with coupons or losing weight.
And with water so inexpensive, there isn’t even the fun of seeing significant cost savings, similar to the dramatic change that homeowners see when upgrading to higher efficiency heating and cooling equipment. Use this water savings calculator to see how much you can save with your local water rates.
The good news is that if you lower your home water consumption, you’ll lower not only your water bill but also your sewer bill, and likely your electric bill. Less water coming into your house, less going into the sewer – everybody wins. Learn more and take the water efficiency pledge at RehydrateUS.org.

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.

On one hand, we applaud the Indianapolis plumber who advises training your house guests on how to use your toilets.
On the other hand, that’s not a discussion Professor Toilet really wishes to have with the in-laws.
If you have a houseful headed your way this month, get a top-rated Champion 4 toilet like the Oakmont.
