The 4 Gallon Rain Basin is our midsize water tank. This tank size is a great mix of high capacity and portability. Like the 2 gallon tank, this tank can be mounted flat, vertically or horizantally, and can easily fit in most locations.
The Rain Basin can be used for rain collection. Simply remove the rain collection cap and set the tank on a flat surface. Then cozy up in your tent and let your tank refill overnight.
And the simplest but most useful feature – the built in water spout. Each Rain Basin comes with a shut off valve water spout at the base of the tank. Instead of having to dismount your tank every time you need to access your water supply, leave your tank mounted and simply open the valve. This makes washing your hands or filling a water bottle quick and easy.
