I'm pretty sure the solution to my toilet problems is to review your toilet buying advice (https://terrylove.com/crtoilet.htm) and buy some new toilets, but is there anything else I should rule out first?
House was built in 1984. I assume all the toilets are the original ones the builder selected.
2 story house built on concrete slab. All 3 toilets have the same tank, marked American Standard, 4083, NOV 9, M84.
Toilet 1 on first floor near front of house, has different base-bowl than the 2 upstairs. It clogs somewhat often and often overflows. In the overflow cases, last flush appeared to go down, but didn't. Next flush overflows.
Toilet 2 & 3 upstairs, base-bowl says American Standard Plebe. Master toilet often clogs. It also often fails to sink the goods w/out sufficient toilet paper to surround them and pull them down.
