Trap condensate
 Trap at all low points and recommended intervals using full size ‘T’ for traps.
 Condensate should not be routed to a sink used frequently by personnel. Route to a floor
drain or equivalent. Condensate normally cools in traps but is still hot. A SAMe or larger
steam line generates more condensate and water may not cool in the trap. A drain water
cooler option may be installed if required by code.
 Route condensate to floor drain or equivalent in multi-unit to single SAM-e installation.
