OPEN VALVE

Valves are found through the water
system allowing

water to flow in certain directions
and keeping it from

flowing in others. Pictured is an
open water valve.

Notice the red handle runs along the
gray pipe below

it. When this valve is closed, the
red handle will run

perpendicular
(like a cross) with the gray pipe below it stopping the water from flowing
through.

All valves
should be marked whether or not they should normally be open or closed.
Typically this

labeling is
done with Red and Green tags. Green for normally open and Red for normally
closed.

A chart
should also be posted on the wall in the RO room with this same information
as well as

a
schematic.
