I'm just curious....

What 3.5 gallon toilet did all of you plumbers recommend before toilets switched to 1.6 gallons per flush? Any that you didn't recommend?

It seemed that back in the day that purchasing a toilet wasn't such a big deal until it was mandated that all toilets today have to be 1.6 gpf. Or was it a big deal back then and were there horrible units that plumbers didn't recommend?

I've noticed in my neck of the woods (Central PA) that there are loads of American Standard Cadets and Eljer Touch Flush Emblems from the 60's and 70's - so they must have been highly recommended.

Just curious as to what the experts recommended back in the day.
