On installing new water-saving tiolets (JIM) I've got two bottom-of-the-line
$46 Home Depot flushers in my house, and they both work quite well. The
thing is, they have to be installed with greater care than old water-wasters;
the extra water made installation *much* more forgiving.
- First, make sure the waste line is adequately sized. When we removed
the old toilet in our house we found it had a 2" (that's TWO-INCH) line
attached. Make it at least 3" (4" would be better, but that would require
that your septic line be 4" all the way out to the street; if your main
is 3", it's against code to install a reducer)
- Second, make sure there's as straight a shot as possible from the
toilet to the sewer main. Our upstairs bath works great because it's
sitting on essentially a ten-foot straight drop before it rounds the
corner to join the main
- Make sure the waste line is adequately vented
