Confusion on Caroma Caravelle One Piece

On the Website of California Urban Water Conservation, there is a list of qualifying High Efficiency Toilets (HET).

https://www.map-testing.com/

There are two Caroma One Piece (Model#989646) with a performance rating of 500;
the other one is Caroma One Piece Easy Height EL ADA (Model#989670) with a performance rating of 800

The ADA version has a higher performance rating so it should be a better model...

I talked to several distributors in the north California area and said the Caroma One Piece Easy Height EL ADA does NOT exist in their database.

I talked to the main distributor and said it DO exist but could provide any further info...


Is there really an ADA version of the Caroma One Piece

If the ADA version really exist then it is the ONLY Dual Flush One Piece Toilet with the highest Maximum Performance Rating

Ya that's wierd there is no mention of this toilet except on Water Saver replacement programs. It shows no list price but all the others do.
