Eljer
I have an eljer in my own house,
they are pretty good all in all
with a full two inch trap going through them
and you can also change out the flapper
from 1.5 to a full 3 gal flush
to make it really roar out if youi so wish..
they have common --easy to find parts.....
now the american standard, I dont think it
could take hamster droppings down without
stopping up...
or leaking out of that stupid little
vent hole in the back side of the bowl...
they seem to be having trouble in our town finding
any supply house who wants to carry that line ....
