A lie is a lie regardless of is “color”. My parents didn’t tell them to me, nor did I to my children. I do recall being told ( and telling my kids), “I don’t know. Let’s look it up.”
I hope your luck with Ratray’s is better than mine. I had a bowl crack which is irreparable (according to 2 pros) and never heard back from them when I emailed for advice. Pipe was under 2 years old.
