Years back I went to Costco and bought a box of their moist wipes. It was only after a $500 drain cleaning bill I noticed the microscopic printing "do not flush."
So more recently Costco began marketing Kirkland (house) brand Flushable Moist Wipes - safe for septic system and sewer."
So far I'm into this experiment to the tune of $790 and the disturbing news the actual pipe from the house to the city's sewer line will cost either $5000 or $10,000. My portion of the line is damaged and the TV camera "locate" showed two large root balls obstructing. So that was another $150 for 2.5 gallons of Crossbow - a really powerful herbicide. One cup down the pan each week followed by two flushes. I cannot imagine what the city would have to say about that, but it was recommended by a licensed plumber.
