Gravity Flush
This is the system toilets have used for over a century: The flush valve or “flapper” opens and water rushes down through the bowl. Manufacturers have steadily improved tank and bowl designs to create a more powerful flush with less water. One of the most effective improvements was to simply enlarge the flush valve from 2 in. to 3 in. or more.

Pros:
•Cost. Some of the models that perform well in lab tests cost as little as $150.

•Easy to maintain. Diagnosing problems and finding replacement parts is relatively easy.

Cons:
•Tanks can sweat. If condensation forms on the tank of your current toilet, the same problem will likely occur with any gravity toilet.

•Big differences in performance. There are still a lot of wimpy flushers out there. You have to do your homework to find a model that performs well (see “Toilet Tests,” left).

My Crane VIP toilet was well rated in Consumer Reports when we built our house in 2003. But now that we have a tank leak problem, it seems to be a 1 time/has-been wonder, with no info or support as to how to fix. It is an oddity, as shown above. Since it's no longer made, and Crane has since been bought by American Standard, help does not look hopeful. Would love to hear otherwise before buying a whole new toilet. Can the current "guts" be removed and another system installed in the tank?

This article has a very misleading title. I expected to find information on improving my current toilet(s) performance and all this article does is talk about three types of toilets with which I could REPLACE my current toilets. The title also says "Step-by-Step Instructions and Pictures" but there are NO instructions at all in this article, just information. I gave it 1 star.
