I've got an older 1970's Kohler that's still going strong.
Remember those 6-7 gallon Full Flush models made before all that "water conservation" crap?
The thing to consider is, I've heard from neighbors that they had to pay a plumber
multiple times to clean out their sewage pipes leading out to the street main - an expensive procedure.
Because the toilet paper and crap gets clogged under the house's pipe because not enough water pushes the crap though, it sticks, builds up, then you've got a problem.
So, I'll stick to the old style flush.
At least I know that the "crap" makes it out to the street in
one flush.
