Toto Flushing System Confusion

[tankertoad]

I am trying to understand if Toto's flushing systems are totally discrete or whether they share components with one another.

For instance, my understanding is that E-Max is an evolution of G-Max, and is identical except for the float on the plunger. So, it's safe to assume that they flush with comparable authority.

I don't know if it's a marketing thing, but the Dual Cyclone is listed as it's own system. But isn't it simply the design of the top of the bowl? What about what's going on in the tank and the siphon and the trap? Doesn't a 1.28 Dual Cyclone toilet share the same flush flapper/valve, siphon, and trapway design as an 1.28 E-Max toilet? Wouldn't "E-Max with Dual Cyclone rinse technology" be more accurate? Or, do the E-Max designs have features not present in the Dual Cyclone designs?

Below are tank photos of the Eco Drake (E-Max) and the Dual Cyclone Gwyneth (aka Ultramax II) . According to the spec sheets, the newer Drake II and Ultramax II (as well as the now discontinued Gwenyth) have a smaller water spot than the Eco Drake and Eco Ultramax.

If someone could shed some light on this, comparing the plethora of Toto toilets will be a lot simpler.


Thanks.

Toto uses three fill valves.
You can pretty much use any fill valve, as long as you are tailoring the amount of refill water for the bowl after the flush.
They do that sometimes by putting in restricters to prevent excess overfilling of the bowl.

Toto uses three flappers.
Blue, which uses the most water
Red, less
Red with a weight, which uses even less.

These toilets use a similar siphon jet trapway design.
They do have two types of rinse.
Those that rinse straight down the bowl
And the Double cyclone that has two rinse outlets near the top of the bowl.

For Toto, E means 1.28 gallons
And S means 1.6 gallons.

The WaterSense product has E labeling.

OK, so the Soiree, Guinevere, Gwyneth, Drake II, and Ultramax II are all identical "underneath" and only differ in their exterior design?

Also, all of the above only come in ADA height. Can we expect any to be released as standard height as well?

If you mean "underneath" that they all have Double Cyclone flush, 1.28 gpf and CEFIONTECT finish then yes they are all the same.

The Gwyneth is the old name for the Drake II (2pc) and the Ultramax II (1 pc).

Those toilets they will not be making in a standard height.

If you want regular height you can go with the Carlyle (skirted) or the Ultramax available in Eco or CEFIONTECT or both. Although neither is available in the Double Cyclone flush.
