The three toilet types selected for our study were a dual flush volume high efficiency gravity flow toilet (HET) with selectable flush volumes of either ~3.9 or ~5.3 liters per flush (Lpf), a dual flush volume pressure-assisted toilet (PAT) of either ~4.2 or ~5.1 Lpf, and a commercial type flushometer (FOM) toilet of ~5.5 Lpf.
In Section 1417(a), as amended, the general prohibitions on the use of lead pipes, solder, and flux do not apply to "(A) pipes, pipe fittings, plumbing fittings, or fixtures, including backflow preventers, that are used exclusively for nonpotable services such as manufacturing, industrial processing, irrigation, outdoor watering or any other uses where the water is not anticipated to be used for human consumption; or (B) toilets, bidets, urinals, fill valves, flushometer valves, tub fillers, shower valves, service saddles, or water distribution main gate valves that are two inches in diameter or larger."
