We have someone in our family who consistently clogs most toilets, even when flushing immediately before adding any paper to the bowl. In fact, that is how they use toilets--flushing twice, once for the "biowaste" and the second time for the paper. But even so, they would clog the toilet most of the time. Unclogging toilets this often is pretty unpleasant, so decided to try to see if we can fine a toilet that worked better and after a LOT of research we chose the Toto Drake 1.6 gallon flush and this worked GREAT! It hardly ever would get clogged. (Sometimes it would still clog but only maybe every other month or so on average.) It was well worth the cost of putting it in.
But we got a new place, and the toilets here clog almost every time that person uses them. So we want to replace them. And the only reason we are replacing them is so that these toilets won't clog. Because the Drake 1.6 gallon flush worked SO WELL, we really want to just go with that again. As I'm sure you can imagine, a new toilet isn't something you can buy to casually "try out" with the intention of just returning it for a full refund if it doesn't work. It has be installed, and once you install a toilet you're pretty much stuck with it--changing it out at that point gets expensive. That's why we want to go with something we KNOW will work.
HOWEVER, we are in California. California requires all toilets to use not more than 1.28 gallons per flush. So the Toto Drake 1.6 gallon flush toilet is banned. Stores won't carry it. Online stores won't ship it to California locations. So the Toto Drake 1.28 is the only one we can purchase here. We are reluctant to buy it because we don't know if it will work. Researching this issue, I found this thread from 8 years ago.
Since this thread first came out is there any better information on how the Drake 1.28 compares with the Drake 1.6 in flushing power? Or is there any other 1.28 gallon flush toilet that works better?
If the Drake 1.6 provides a better flush, then we want to go with that. We can still get Drake 1.6 toilets, but this would require driving to another state. It would take a full day and require an 8 hour drive. But toilets are something that get used every day and we expect that whatever toilets we install, we will be using for a long time. So I'm thinking making the drive may be worth it. But if it turns out that the 1.28 Drakes work just as well, then maybe I should consider going that route?
