INSPECTION
1. Clean all parts, sealing surfaces and threaded areas with a mild soap and water solution. Remove
any foreign matter with a stiff bristle brush. Wipe parts dry with rags.
2. Inspect coupling half (1) and gate valve (2) for cracks, dents, stripped threads and wear.
3. Inspect pressure gage (3) for a bent indicator (11) or broken faceplate (12). Check pressure gage
operation by physically blowing air through the end of pressure gage (3). Average lung pressure
should read between 2.0 to 2.5 psi (14 to 17 kPa).
4. Inspect rubber adaptors (10) for cracks, tears and rotting.
REPAIR
1. Replace coupling half (1), gate valve (2) or rubber adapters (10) if damaged.
2. Replace pressure gage (3) if damaged or if lung pressure test reading is under 2.0 psi (14 kPa).
INSTALLATION
Gate Valve
NOTE
Moisten the inside of the rubber adaptors for ease of inside flange installation.
1. Install the two rubber adaptors (10) on the gate valve (2) tube.
2. Install the inside flange (9) between the rubber adaptors (10).
3. Align gate valve (2) and top and bottom pipe clamps (7and 8) on tank. Install four cap screws and
washers.
4. If two adjacent top and bottom clamps (7and 8) were removed, align clamps (7 and 8) and install two
more cap screws and washers.
5. Torque all screws to 70.0 ± 5.0 ft-lbs (95 ± 7 Nm).
Pressure Gage
1. Install elbow (4), drain cock (5) and pipe nipple (6) on pressure gage (3).
2. Install pressure gage (3) on the gate valve (2) fill tube.
Coupling Half
Screw coupling half (1) on end of gate valve (2).
