You Can’t Flush Tampons Down The Toilet .

I've been (among many other things and many other qualifications for those things) a licensed Master Plumber for decades and I can tell you that tampons are a HUGE cause of clogged pipes not just in homes but in commercial plumbing systems as well. That said, it's so common to encounter them when you do a video sewer inspection or run a Roto-Rooter-style sewer/drain cleaning machine through not just "soil" pipes where #2 goes down and out but also the waste arms of lavatories and other sinks which are "grey water" sources not black water like commodes produce that they're called "sewer mice"; in fact when I was a young apprentice and still somewhat naive it took the journeyman plumber I was helping to explain to me how we just extracted two very full Tampax out of a lavatory (the sink in a bathroom) drain which was at the end of a ten foot 2" pipe arm and many more feet away from the commode in the bathroom, he explaining when the sewer backed up which is why we were called there in the first place the tampons which had been part of the original clog that they simply migrated to the highest point of the back up which was the lavatory drain. I also had to replace an entire sewer system for a business that employed several women in their office and no men all of whom were flushing not just Tampax but full-sized Kotex as well which of course kept clogging the main 4" sewer line out to the street the old sewer line being installed decades before and had settled out not just level but in some cases the wrong direction which kept creating clogs of course which meant that literally every month we had to run the RotoRooter machine through it, yeah, geez. And one last point: yes, sanitary products are such a nuisance in municipal waste systems that sewage treatment plants all have these super-duper screening systems costing in the hundreds of thousands of dollars or more designed to catch and remove anything in the sewer flow that's not supposed to be there, not just feminine products but yard waste, parts of human remains (no kidding!), ordinary household kitchen garbage that should have been put in the garbage in the first place, anything metal and anything plastic, basically anything that's not pee or poop has to be caught and filtered out before the waste water itself goes into the treatment plant for processing.
