CHAPTER 4 · GREEN PLUMBING SYSTEMS 181 The urinal bowl surfaces are smooth and urine repellent; urine is 95% liquid and its drainage is effected without flush water through gravity. Daily cleaning procedures are the same as for flushed urinals, yet save time per urinal. The conventional water-filled urinal trap is replaced by a disposable trap (Figure 10) inserted in the urinal drain outlet of our urinals. It holds a layer of the proprietary immiscible liquid, floating on top of a urine layer. The combination of the trap and the covering liquid blocks out sewer gases and urine odors from the restroom. A three ounce dose ofliquid lasts up to 1500 uses, replacing from 1000 and up to 4500 gallons of quality potable flush water at each fill! ! . n:"..-:.'''i'..o:':">...,....''"'~':. e..'. . Energy Efficient Washing Machines FIGURE 11 In recent years, clothes washer technology has seen dramatic improvemen. effic cy and functionality. Selecting an ENERGY STAR qualified washer nsures premiu atures and equal functionality, in addition to the following benefit. Purchasing ENERGY STAR qualified model rather than a non-qua' led model will save an average of 0 a year on utility bills. Washers built before 98 are significantly less efficient th newer models. If the washer is more than 10 year ld, a homeowner will pay abo $135 more each year on their utility bill than if they ned a new ENERGY :AR qualified model. New ENERGY STAR qualified clothes ashers use adv ed technology to dramatically reduce water use. A non-qualified cloth washer wi se 17 more gallons of water every time a load of clothes is washed. That was wat is equivalent to a daily shower. Instead of twisting and pulling clothes arou . g agitator, front-load and advanced top-load clothes washers use sophisticateg, ash sy IDS to gently flip and spin clothes through a reduced stream of water. Thi~kngthens the of often-washed items. Because they are so gentle, many models c91<' safely clean silk, w I and other hand-washables. Without a bulky agitator, there is ;n6re usable space in the wasH for laundry - especially larger items like comforters. re capacity means fewer loads of la dry each week. Efficient motors spin othes two to three times faster during the Spl cycle to extract more water. Less mo' e in the clothes means less time and energy in the er. RGY STAR qualified dishwashers save money. They use 31 % less energy and 3 0 less water than conventional machines while delivering superior cleaning p. ormance. Technology has improved dramatically over the last decade. New ENERGY TAR qualified models include several innovations that reduce energy and water .consumption and improve performance.
