Very likely that the wet wipes you refered to are causing the problem. Regardless if the packaging says you can DO NOT FLUSH THEM! I've augered out many a toilet that I've brought back these "FLUSHABLE" wipes or cleaning towels that when unfolded are still full size. They do not break down.
I always tell my customers to only flush these 3 P's
#1 - PEE
#2 - POOH(Not Winnie)
#3 - Paper (Toilet)
And never these P's (Found these & then some - That's another tread!)
#1 - Pads
#2 - Pons (Tam)
#3 - Plastic Applicators (See #2!)
#4 - Prophalactics
#5 - Perfume bottles
#6 - Phones(Cell)
#7 - Pens/Pencils
#8 - Pot (Drug enforcement usually gets this)
#9 - Pig (Actually Ham Hock - Bean soup POT dumped into toilet "DISPOSAL" - This did not auger out - She was happy with the new toilet I had to install)
And if they insist on flushing items not in the first set of 3 items I get something...
