Semi-Annual Inspection
The semi-annual inspection should be performed six months (+/- two weeks) from the tank’s wet date or 12
months from the manufacturing date, whichever comes first. The semi-annual inspection includes a visual
inspection of the inner bladder condition.
1.
Open the outer tank zipper. Inspect the space between the inner and outer tanks (within reasonable
reach) for signs of leakage. Also, inspect the inner and outer bladder fabric condition. Special
attention should be paid to the area closest to the handles and around the flanges. Do not disas-
semble flanges or disengage handles.
2.
Before closing the zipper, lubricate both halves of the zipper with zipper lubricant. Close the zip-
per slowly to the end, making sure that all zipper teeth are engaged. Wipe away any excessive
lubricant.
3.
When the tank is filled for the first time after an inspection, open the zipper ¼" to ½" just to create
enough opening for air to escape. After filling tank and releasing the air from the space between
the inner and outer bladders, close the zipper to the end.

Important Note
If a leak is discovered, the BATT must be drained completely and sent to SEI Industries for
possible repair and re-testing.
