1-10. LOCATION AND DESCRIPTION OF MAJOR COMPONENTS.

The 20K and 50K Gallon Collapsible Fabric Tanks are supplied with all major components necessary to make the tanks

operational. For the purpose of this manual, the 20K and 50K Gallon Collapsible Fabric Tanks will be addressed as kits

comprised of the following major assemblies and components.

a. Tank. The collapsible water tank (4) is used to store potable water. Openings in the top of the tank allow

connection of the vent, filler/discharge, and drain fittings. Handles (11) along the tank perimeter aid unfolding,

positioning, and folding of the tank.

b. Fitting Assemblies.

Drain Fitting Assembly. A drain fitting (6) consisting of a low profile adapter and plug is mounted on the bottom

surface, toward one end of the tank. When the plug is removed, the (drain) hose assembly (5) can be

connected.

Vent Fitting Assembly. The vent fitting (2) connects to the top of the collapsible water tank and prevents

damage caused by over pressurization. Venting of tank pressure is automatic and no operator control is required.

A protective dust cap is provided to prevent entry of contaminants when tank is not in use.

Filler/Discharge Assemblies. A filler assembly (3) and discharge assembly (1) are located on top of the

collapsible water tank. Both assemblies are supplied with a 4-inch 90elbow for use in connecting the tank to

water distribution system hoses. A protective dust cap and plug are provided to prevent entry of contaminants

when tank is not in use.

c. Accessories.

Hose Assembly (Drain). The hose assembly (5) is comprised of an 8-foot section of hose with a hand operated

gate or ball valve attached to one end. The hose is connected to the tank drain fitting during installation and allows

operator control of tank draining.

4-inch Gate Valve. The 4-inch gate valve (8) allows operator control of water inlet or discharge. The valve may

be connected in either the system fill or discharge hoses, or connected directly to the filler discharge fitting

assemblies.

d. Ground Cloth. The ground cloth (7) provides protection for the water tank bottom surface. Fourteen handles aid

positioning and installation of the cloth.

e. Repair Kit.

Sealing Clamps and Plugs (10). Used to make temporary repairs to the water tank fabric.

Gaskets and o-rings (9). Used to make repairs to cam-lock couplings, fitting assemblies and 4-inch gate valve.

These parts are packaged as spare parts with water tank system.
