We bought the home new five years ago.
It came with Mansfield Alto round bowl toilets.
All three plugged the first day we moved in.
They plugged often.
Then two years later, my son replaced the downstairs toilet with a Sterling Wyndham 1.6 gallon toilet.
That was an improvement, but still plugged it occasionally.
The two years ago, that was removed and replace with a Toto Drake toilet.
The Drake has never plugged.
I like the fact that we got the elongated bowl, and the softclose seat.
Not only does it work well, but it's comfortable.
