Will tall toilet toilet meet 1.28 gallons per flush (1.28gpf) ?

Yes. This decision was made on Earth Day, April 22, 2017, and it was the right thing to do.

Does your 20 inch height tall toilet flush well?

Yes. Actually, it flushes better than most siphonic toilets – and here is why. Our super tall bowl elevation adds some more power to the siphonic flush, based on height and gravity physics; all contents rush downward drain moving incoming water at a naturally increasing flow speed. Convenient Height 20″ toilets have the advantage of added steeper elevation which is naturally good for a stronger siphonic action. Right after the trap way bend, the route is downward all the way into the drain, with literally no resistance at all. The Convenient Height Co. production plant tested Model S toilet with 3 ping pong tennis balls and additional hard items in the bowl at the same time and it flushed well; additionally, it passed the 1000 grams. hard artificial waste flush testing.

Flush rating on this toilet? (MaP)

MaP guidelines were used for our flush rate testing and we did a MaP type flush test at our factory that shows a result close to 1000 grams in one flush. We are confident it will yield similar result in MaP’s test lab should we decided to go for a MaP rating later.

Pressure assist (air pressure) flush systems question
Pressure assist air pressure flush systems

Thank you for your question. As you said in your note, “Air pressure flush system is used by the businesses and stores”.. which in other words means – for toilets in the Commercial setting. Commercial drains are not the same as residential and commercial buildings have more complex plumbing systems. Strong water pressure is needed to push water up multiple floors and with the web of drainage pipes, the same principle of power is for contents going down from sinks and toilets. Please also do not forget the main reason Commercial buildings need pressure assisted toilet flush – in commercial bathrooms, there is a lot more stuff thrown to flush that does not belong in the toilet drain!..
So while technically you can get a pressure assist system for a residential toilet, please ensure your home piping can handle the added air pressure. Your plumber is correct to say “air pressure flush system helps keep the sewer system clear and that low flush toilets are causing sewer problems”. But – can has your residential drain been tested to handle air pressure delivered by air pressure device and do you really need it?..

With our Tall Toilet, there is something we engineered better than many others, and it is a gravity-based powerful flush. Please take a moment to watch videos on our website (link here https://convenientheight.com/videos or our youtube channel) as it relates to toilet flushing. We show how much of contents and how well our Convenient Height tall toilet flushes it all down. A good gravity-based powerful flush (like ours) is much safer for your residential drain pipes than the air-pressure designed for commercial setting. Our bowl is engineered to delivers plenty of pressure to push contents down the drain.

How does your toilet flush power compare to American Standard Champion 4 Max toilet?

Flush power: when it comes to the flush power we do have a good flushing toilet with a Dual Flush valve (handle up for less water dispensing around 0.9 GPF and handle down for full flush of water dispensing 1.28 GPF). Here below attached are some of our Convenient Height flush testing videos. The American Standard Champion 4 Max sure is a well-flushing toilet, but of course if you are looking for a super powerful flush for any particular reason, then the most of the flush power will come from pressure-assist toilets – which is neither Convenient Height and not the American Standard Champion 4 Max unit. Both our Convenient Height brand and the American Standard Champion 4 Max have a very well performing flushing gravity based flush toilets and we are both high-efficiency design with a 1.28 GPF for a full flush (except that we also have a dual flush option with our dual flush 2 inch valve). Please review the flush videos (links below) and let me know if you have any questions.

Air venting for drain pipes
Plumbing Vent
Example of Plumbing vent pipe on the roof

Air is critical to the drainage process because drainage flow is caused by sloping pipes, and the motive force is gravity. Without proper air flow, you may experience slow drain performance or a gulping sound in your fixture. Plumbing air vents also prevent sewer gases from entering the home and allow wastewater gas and odor to escape. Plumbing vent pipes are located on roofs, away from windows or air conditioning units, so that the fumes can easily dissipate. Proper ventilation is especially important for a good drain action.
