Can you flush paper towels with a septic tank?
The short answer for paper towels and a septic tank: never. Paper towels are made to stay strong when wet, so they do not disintegrate in the tank the way toilet paper does.
They gather at the inlet and form clogs that can back the system up into the house. Throw used paper towels in the trash or compost.
