mansfield ecoquantum 147-119 vs 148-119

this is likely a stupid question but I'm looking to replace my old Eljer toilet and currently have a vanity banjo top which is only 31.5 inches high. Makes things pretty challenging when everything seems to be heading to the confort height in toilets. Does anyone know if there are any performance differences b/t the mansfield ecoquantum 147-119 vs 148-119 or if it is just the smart height?

Performance should be similar if not identical. Should the need arise, unless it's hinged or removable, a banjo shelf with limited clearance makes it extremely difficult to service a pressure-assist system.

Generally the higher (ADA or Comfort Height) toilets perform slightly better than the same model in the regular height...

Consumer Reports in the August 2009 issue picks the Gerber Dual Flush as their top choice for dual flush toilets.

However, we no longer sell the Gerber with WDI Dual Flush combination.
We have had to replace more than 40% of the tanks in the first year of production due to failure of the actuator mechanism.

They are a piece of junk.

Shame on CR for not doing your homework.

This dual flush tank has been on the market for a year now.
It's a design that should have never left the factory.
If Consumer Reports had any feeling for the consumer, they would have given this model a "Don't buy" rating.

If you buy a Gerber Ultraflush, don't get the dual flush.
The 1.1 Flushmate or the 1.6 Flushmate would be a better choice then the Dual 1.1/1.6 made in China that is failing too often. When 40% fail in the first year, that is ridiculous
