outside shower

I use a 3 gallon spray pump that is made from black plastic, originally for spraying chemicals like weed killers and fertilizer. The black plastic absorbs the heat when left in the sun and when you pump it up you can get several showers without re-pumping. I use it when I camp at the beach with no hook ups. I use it for rinsing the salt water off after swimming and sand off the feet before going into the MH. No I never used it for it original purpose.
