(6)
Tighten the wing nut to securely clamp the tank wall between the two plates. Tighten enough to stop leak.
If pliers are used, DO NOT exert extreme tightening that might strip the threads of clamp stud or that might
damage the tank fabric.

Remove the nylon cord if desired.

Emergency Repairs With Wooden Plugs
(1)
In emergencies, as an immediate temporary measure, the furnished wooden plugs may be used for
expedient sealing of small holes or punctures. (Fig. 3-2).
(2)
Select the size plug needed to fit (seal) the tank puncture, insert in the hole and twist clockwise until the fit
becomes quite snug and the tank leak is either stopped or slowed to the greatest possible degree. Follow-
up regular inspection should be made of the inserted plugs, as possible tightening of the plugs may be
necessary if the leaks resume. Later, if a leak is not totally stopped, the use of a small repair clamp may
become necessary.
(3)
The size of hole or tear will determine the size of wood plug to be used.
(a)
For holes (tears) up to approximately 1/2 inch in size, use the 3 inch long plug.
(b)
For holes (tears) up to approximately 1 1/2 inches in size, use the 5 inch long plug.

Repair
NOTE
This procedure consists of patching cuts and punctures in the tank fabric. If tank
must be put back in immediate service, or materials are not available, perform
emergency repairs, paragraph 3-5.a or 3-5.b, instead of this task.
There are three methods to repair tank fabric which holds water.
Preferred Method: Patches are used on both inside and outside of tank.
First Alternate: Single patch on inside of tank.
Second Alternate: Single patch on outside of tank.
Fabric which does not hold water needs only one exterior patch.
1.
Ensure that all components of the repair kit (ROCTAD) are present before starting repair. See Table 3-3.
