3.1L of water
The CPS 2500 a 1998 CPS series Super Soaker that holds 3.1L of water. It is no longer available for purchase, since its home line has since been discontinued. It is classified as an elastic-pressurized blaster. It is a variation of the CPS 2000 Mk 2 that is recoloured and equipped with a three-setting nozzle selector. Other than that, it had the same amount of power.
