It’s a GREAT thing to have an old american standard in an upstairs bathroom to help wash things out of line ...
Wifey wanted me to change everything to low flow toilet wise, but the toilets at the end of the line I left as conventionals to help the system clear itself.
Main line preventative maintenance -
Tree root killer if you have big tree’s in the front lawn - flush it a couple times a year if not more.
And teach them NOT to dump grease, baby wipes, paper towels, etc down the drain.
