does anyone know whether or not salt water (say draining a 125 gal. tank) is harmful to septic system? both to the bacteria in the septic tank and the drain field. i injured my back and not supposed to lift heavy things (like 5 gal. bucket of water=40 lbs, 125/5 * 40= 1,000lbs) i was planning to use the python system to drain the water directly into the kitchen sink.
