WATER CONTROLS
Your home has a built-in fire sprinkler
system. If you have a fire, the sprinklers
will put it out or control it with water.
The system protects your family and
home from the dangers of fire, 24 hours
a day.

Keep Valve Open
Domestic Water
In most cases, sprinkler systems are
supplied by the Water Main, where
water comes into a home. The fire
sprinkler system connects to the water
main. In Illinois the water flows through
a Backflow Valve. Typically, a DoubleCheck Backflow Valve (DC) is required.
For systems with anti-freeze, Reduced
Pressure Zone (RPZ) check values are
required. A main water control valve is
on the pipe that supplies the sprinkler
system. This Control Valve turns the
water flow on and off. Your system may
have additional or different features.

CONTROL VALVES MUST BE OPEN OR TURNED ON.
The control is OPEN when it is in line with the pipe.
WATER CONTROLS
OPEN
The control is CLOSED (“turned off”) when it makes a corner
to the pipe.
Make sure nothing is blocking your sprinklers.
Hang lamps and plants away from ceiling sprinklers.
Do not hang anything on sprinklers or pipes.
CLOSED
Even lightweight items can damage sprinklers.
Keep paint away from sprinklers or sprinkler covers.
Keep the area around your water controls clear.
Do not store anything within 1 foot (30 cm) of your water
controls.
SPRINKLERS
NEED SPACE
Keep pictures and large furniture away from sprinklers on walls.
Use a padlock to keep the valve LOCKED OPEN.
Tape the padlock key to the pipes or a wall nearby so you can
find it when you need it.
PROTECT YOUR FIRE SPRINKLERS.
LOCKED
OPEN
If sprinkler water control valves are ever turned “off”, be
sure to turn them back on.
The water needs to be turned on so the sprinklers can work
to protect you from a fire.
While doing messy work, such as painting, cover the
sprinklers with plastic. Remove the plastic as soon as you
are finished.
Be careful when you are moving large or tall items.
Don’t bump sprinklers or exposed pipes. Teach children not to
touch or play with sprinklers.
