•
Never exceed stated psi in tank.
•
Bursting tank may injure or kill.
• 4.3.3.1 Tank Integrity
At the start of each shift:
•
Inspect Interior:
Drain the tank of water and use a
flashlight to look into the tank through the fill opening.
Look for signs of corrosion on the inside of the tank which
may indicate that the tank has been weakened and is in
need of replacement.
•
Inspect Exterior without Pressure:
If the interior
inspection indicates that the tank is in good condition, fill
the tank with water and inspect the exterior of the tank
thoroughly for signs of leaks. Inspect the filler neck and fill
opening. Look for signs of damage.
•
Inspect Exterior with Pressure:
If there are no signs
of exterior leakage, pressurize the tank and repeat the
inspection.
•
Depressurize Tank:
Release the pressure in the tank as
soon as you are finished inspecting and before moving
the truck.
Replace Defective Tank:
Water tanks with any leak or
significant signs of internal or external damage or corrosion
should be replaced. DO NOT ATTEMPT TO REPAIR.
• 4.3.3.2 Pressure Regulator Valve
Inspect Pressure Regulator:
The pressure regulator is used
to reduce the air brake system pressure to a pressure that is
safe to be used in the water tank. It must be undamaged and
in proper working order. Look and listen for signs of leaking.
Ensure that the valve and associated hoses and fittings are
undamaged.
Adjust Pressure to Correct Setting:
Many pressure
regulators are set at the factory and cannot be adjusted.
if your water tank has an adjustable regulator, set it to 50
psi. When setting the regulator, always begin by turning the
adjusting knob counterclockwise first to reduce the pressure
slightly. Then turn it clockwise slowly to bring the pressure up
to the correct setting. Never continue to turn the valve past the
correct setting.
Replace Defective Regulator Valve:
Any water tank with
a damaged or missing pressure regulator valve must be
removed from service immediately. Do not pressurize the tank
until a functioning pressure regulator valve has been installed.
