How do you flush your veins safely Should water be used or Saline solution?
Are you asking how your body flushes the vein? The body is responsible for doing so through the lymphatic system. All the tissue fluid (dirt and recyclable materials) are recycled in the process in turn for clean oxygenated blood.
How is blood kept moving backwards in your veins?
Your veins have a system of valves that work to keep the back flow of blood from returning the areas where blood has already passed. Once the left ventricle of the heart has finished contracting, gravity will tend to pull blood downward. When this happens, blood pushes back the valves, forcing them closed. The valves will reopen when the force of the blood being pumped exceeds the amount of force opposing the valves.
As a side note, valves work to allow flow of a fluid in one direction only. Sphincters (such as your cardiac sphincter in your stomach) allow for fluid or in the stomach's case, a bolus, to enter and exit your stomach, allowing an individual to vomit. Rats and horses do not have cardiac sphincters, thus making it impossible for them to vomit.

What helps veins carry blood to the heart?
Passively.
The blood comes out of the capillaries with a residual pressure (given to it by the heart). There are valves, but they are present just to prevent (reduce really) back flow. There is some pressure added externally by the leg muscles when walking, but the lack thereof is only noticed on parade grounds when solders stand at attention for too long.
