Water Long Term Storage

  1. Make sure tank location is on level ground and protected from traffic flow.
  2. Clear the area from any debris and use a pad or plywood for protection of the tank.
  3. For installing under a crawl space, make sure that the tank has enough clearance from the floor joists and no sharp objects are protruding down.

Filling the Water Tank

Using the 4" Opening

  1. Make sure the ball valve is in the closed position. Unscrew the red cap, insert the hose, and begin filling.
  2. When water overflows from the opening, remove the hose and screw on the cap.

Using the Ball Valve

  1. When filling from the ball valve, remove the red cap, attach the hose to the ball valve, open the valve, and begin filling.
  2. When you see water overflowing from the 4” opening, shut off the flow and screw on the red cap.

*Do not hang tanks by the eyelets. Eyelets are only to be used when securing the tank to the ground or a truck.
**Do not leave the tank unattended while filling
