Description
Although there are numerous anecdotal stories attributing drain-line problems to the use of 1.6-gallon toilets (especially in cases where the drain line services only a single fixture), there is littlefield data to support these claims. Several laboratory studies of “line carry” have beencompleted, but most studies caution that the use of sponges, plastic balls, etc., may not accuratelysimulate “real world” conditions.The intent of this study was to provide science-based data on the effectiveness of popular toiletmodels to transport solids to the sewer, i.e., drain-line carry. The study involved physicallymeasuring the effectiveness of several different types of ultra-low-flush (ULF) toilet flushingsystems to transport a realistic test media (soybean paste and toilet paper) along drain linesinstalled at different slopes. There is a real need to identify if the installation of ULF toilets, especially in olderbuildings, can lead to drain line problems, and therefore, flushing performance problems. Thisproject is intended to answer these questions, and thereby enable appropriate policy, code, andeconomic decisions to be made.
