DUh, you can’t flush those. They are very useful but not flush able.
She did not realize it: the only reference to them being unflushable was a very small icon on the back of the package showing a person tossing the wipe into a toilet with a superimposed crossed circle over it. No words, just the (very tiny) picture.
Truthfully, wiping with toilet paper is neither efficient nor sanitary, compared to flushing the area with water, which removes far more feces, then just drying with a little TP.
Once you get used to flushing, it is pretty obvious that wiping with TP is just gross.
A simple, inexpensive means to do so is to use a suspended hot water bottle, rigged as an enema device, but not inserted, just washing the area. It really does a much better job.
Some toilets are now coming equipped with water nozzles under the rim, for that purpose.
I know they say flushable, but that’s dumb. Whatever they say, it’s just not worth clogging the pipes and keeping RotoRooter in business.
Logically, if they are made to wipe wet, they will not break down when flushed. Probably would fill up a septic with inert mass as well.
