Cleaning of Tank (Temporary and Long Term Storage)
The tank is easily cleaned after normal usage.
With the tank empty and flat in the truck, partially fill it with 100 to 300 gallons of clean disinfectant and water
solution. The solution consists of 1/2 gallon of commercial bleach mixed in 250 gallons of fresh water. Surge the
cleansing solution by walking back and forth on the tank or by rocking the truck with abrupt starts and stops. The
resultant surge will clean or rinse the collapsed tank without exposing its interior to contaminants or foreign
objects.
When the cleaning solution is drawn off, close the tank valve immediately to hermetically seal out contaminants.
