: I have two 30 year old American Standard toliets that have recently stopped flushing completely.It takes sometimes 3 or more flushes to do the job. I had a plumber come out an snake the line and it worked fine for a week.I had another plumber come out to snake the main cleanout but he told me that I needed new toliets instead. They had worn out? He said if the main line was blocked I would have water backing up the other drains;tub,shower,sinks,ect.
: How does the porcelain toliet wear out ? I am sceptical.
