Plumbing. If the building is to be inactivated without heat or
2.2.3.4
water service, the following applies. All plumbing fixtures and supply piping
should be drained, including hot and cold water storage tanks, in buildings
not required for use by maintenance personnel. Supply lines for gas, air,
water, and other liquids should be closed at the curb valve. Moving parts of
the master valves within buildings should be removed and greased. When the
curb valve is not of the stop-and-waste type, water should be pumped from the
line between the master valve and the curb valve. Water traps on gas and air
lines should be drained. The hot and cold water service lines should be
drained through valves located at the lowest point in the system. Storage-
type water heaters should be drained. Reservoirs, standpipes, and tanks
inside or outside buildings should be drained of all liquids unless they are
kept in service for fire protection or other purposes. All traps located at
plumbing fixtures and drains in the sanitary system should be drained of their
respective water seals. Traps should be immediately refilled with antifreeze
to the normal water seal height. Antifreeze types should be approved by
NAVFAC Code 10. This will prevent freezing in temperatures below 40 degrees F
and bacterial growth in higher temperatures. Built-in trap seals in plumbing
fixtures should be drained or treated with antifreeze; other trap seals should
be drained by removing the cleanout plugs.
All sources of air contamination in buildings, such as drainage
sumps, cleanouts, traps, grease interceptors, and industrial waste separators,
should be emptied and cleaned. Sanitary sewer lines should be plugged to
prevent the entrance of sewer gas into unoccupied buildings through plumbing
fixtures and drains. Care should be taken, however, to preclude stoppage of
drain lines that serve the roof,. the floor, the area drains, and other
connections that must be kept in service. Sewer lines that connect to
manholes and do not carry storm water may be plugged in the manholes; a record
should be kept of all plugged sewer lines.
Building Mechanical Systems Reactivation
2.2.4
General. When reactivating engines and compressors, give special
2.2.4.1
attention to the warning tags left on equipment at deactivation, with specific
attention to lubrication systems. Use oil conforming to Military
Specification (MIL)-L-9000H, Lubricating Oil, Shipboard Internal Combustion
Engine, High Output Diesel, Seasonal Grade. All engines, pumps, compressors,
electrical switchgear, transformers, electric motors, heating systems,
boilers, water-softening and filtering equipment, and controls will require
inspection, testing, and restoration to normal operation. Installation of
items placed in storage, lubrication, and replacement of deteriorated parts
will also require attention.
Compressors. Compressors having a separate crankcase should have
2.2.4.2
the preservative oil removed from the crankcase and replaced with the proper
grade, viscosity, and quantity of operating lubricating oil. Tighten all
bolts, nuts, and capscrews. Turn the compressor over by hand to ensure that
