MARINE TANKS should always be stored out of direct sunlight and protected from freezing. Prior to installation, tanks should be at room temperature for a minimum of six (6) hours. The tank must be installed on a flat or contour matched surface, be clean and totally supported in all planes with 1/2" - 3/4" marine plywood or equivalent.
Install tubing and fittings so that there are no points of stress on the tank. Use elbows to prevent partial bending or collapsing of the tubing when a change in direction is required.
Plastic tank connections are designed to seal dry. Compounds such as sealants, pipe dopes, greases, petroleum jellies, glues or adhesives are not to be used. Normally, hand tightening will provide adequate seal. On occasion, a slight tightening with a wrench may be required. To avoid damage to seal fittings, do not apply excessive force. Do not exceed 1/4 turn after hand tightening.
Do not install metal fittings in the plastic tank as the materials are not compatible.
Should you desire to test the portable water tank or water system for leaks, fill with water and check visually.
