A. Most residential toilet tissues will work fine in a VacuFlush toilet. However, a few can be troublesome in any toilet system (including home toilets). These troublesome tissues contain adhesives that bond together the paper fibers from which the tissue is made. The adhesives prevent the tissue from breaking apart, and their use in any toilet can cause blockage. One brand of tissue we don’t recommend is Charmin® Ultra (trademark(s) of the Proctor & Gamble). SeaLand brand tissue is especially formulated for use in low water consuming toilets. Its rapid dissolving properties prevent tissue paper from accumulating in the holding tank or elsewhere in the system.
