intended to produce hot water. Water heated to a
temperature which will satisfy clothes washing,[ dish washing, and other sanitizing needs can scaldand permanently injure you upon contact, Some/
people are more likely to be permanently injured by hot water than others, These include the elderly,
children, the infirm, or physically/mentally handi- capped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special pre-
cautions. In addition to usmcj the lowest possible
temperature settingthat satisfies your hot water needs, a means such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at
plumbing supply or hardware stores. Follow manu- facturers instructions for installation of the valves,
