–can usually be installed by consumer on shower head or faucet
In
multi-family housing, the average hot water temperature sometimes will vary
greatly from one unit to the next.When a building’s hot water system cannot supply consistently safe
water to some units, certain devices may help reduce the scald risk.These
come in two types:measures designed
to controlwater temperature, as
listed on this slide, and those designed to prevent people from falling into
hot water.We’ll call them direct and
indirect scald prevention measures.
As a direct scald
prevention measure, a tempering valve mixes heated water with whatever
cold water is needed to keep the temperature below a specified maximum level.
A plumber can install such a valve at a connection of the hot and cold water
lines. This is most easily done somewhere near the heater during initial
construction.
The alternative
direct approach is to install an anti-scald device at the shower head
and any faucet which combines hot and cold water. Screwing such a valve on
the fixture ordinarily does not require a professional. These devices work by
halting the flow of hot water until the temperature of the water
flowing through the valve falls below a pre-set maximum level.
