The modern household is filled with products labeled "flushable," a term that is frequently misleading. "Flushable" wipes, feminine hygiene products, paper towels, and cat litter do not degrade like toilet paper. They weave together within the tank, creating a thick mat that clogs inlet and outlet baffles—the critical checkpoints that keep the system flowing.
