Ask me about the huge wad of baby wipes my plumber pulled out... I though the PO flushed some rags or shop towels.
It was an ORDEAL. I had just bough the house and we didn't even have a baby... Turns out it was my wife all along...
They say right on the package if they are flushable or not.
This happened on an Easter Sunday while we were both flying out for work. Plumbing bill was insane and we had to project manage this while she was in London and I was in Indianapolis.
