The check valve acts as barrier so that no back flow is allowed into the main water line from the chemical or fertilizer storage tank. This is accomplished with an approved spring loaded device, some times using a stainless steel ball, disc or rubber stopper. The spring action is rated by pounds of pressure so that the device will not open and allow flow without reaching the listed pressure first, normally referred to as the cracking pressure.
