What toilets think of gDiapers.

A third-party, independent laboratory tested the ability of a flushable inner pad of a gDiaper to pass through typical North American household toilet fixtures with the addition of a 60-foot length of four-inch diameter glass pipe attached to the toilet discharge. Observations were made of the travel and condition of the inner pad in the drainage pipe. Test guidelines were based on the Water Environment Research Foundation (WERF) "Protocols to Assess the Breakdown of Flushable Consumer Products" method A.1 "Screening Toilet Bowl and Drainline Test," the current industry standards for assessing flushable products.

Six toilets, representative of toilets currently in domestic use, were used in the evaluation (see table below). All toilets are considered low consumption models (approximately 1.6 gallons or less). Based on all six toilet fixtures, the gDiaper flushable pad met the WERF acceptance criteria for bowl and trap clearance.

* For pressure-assisted toilets such as the Mansfield Quantum, the tests indicated that the minimum static water pressure should be 35 psi for the product to be evacuated successfully. The tests also indicated that the product should not be recommended for use in this type of toilet with a pressure lower than 35 psi. It should also be noted that pressure assisted siphon jet toilets with a low static pressure (e.g. 20 psi) do not flush well under normal circumstances. The flush volume was measured as 0.9 gallons at this pressure, contrasting with its rated volume of 1.3 gallons compounding the problem of reduced pressure.
