There is nothing wrong with the pipes that are draining the toilet.
I find that quite a few pressure assist toilets will shred paper and waste matter and float it back into the bowl.
Consumer Reports "Best Buy" Eljer Aqua Saver with PF/2 pressure assist did the same thing.
It's fine as long as you only flush wipes and sponges.
Kinda sucks for real world use though.
And it's just for these examples, that I supply a report on toilets, so homeowners don't waste money on "un-tested" products.
I consider any toilet tested in a lab, as "un-tested"
At some point, someone has to get down and dirty and really use them for any of it to be useful.
Glacier Bay 1.0 GPF Pressure Assist toilet N2310E with Sloan Flushmate IV
I installed a new Galcier bay 1.0 pressure assited model and so far the flush is just awful.
The water pressure when the toilet is flushed seems fine, in fact , I think it make be too powerful.
Everytime I flush there is paper and other matter that re appears. It's almost like the powerful jet of water is shredding the paper and other stuff into small peices and kicking them back into the bowl.
