REPAIR OF CANVAS PRODUCT WATER AND BRINE WATER TANKS
General. Canvas tanks with rubber backing are used to store product water and brine water. Sometimes
these tanks may be cut or punctured. Tanks then leak and must be repaired.
To avoid possible damage, the site should be free from stones or sharp sticks, be fairly smooth, and
covered with the ground cloth before the tank is placed on ground.
Repair. If a tank is punctured, use the oval sealing clamps supplied in the repair kit to make temporary
The tank does not need to be drained to make these repairs.
Determine the size of sealing clamp needed. If the hole or slit is up to 2 1/2 inches (6.35 cm) in length,
use the 3-inch (7.62 cm) sealing clamp. If the hole or slit is 2 1/2 to 4 inches (6.35 cm to 10.16 cm) in length, use the 5-

Rotate the outside clamp to line up with the inside clamp.
Center both clamps over the slit, pull them together with the rope, and tighten the wing nut as tight as
possible with your fingers.
