Great stuff! Now I wonder what the "empty" tank would look like without a three foot drop at the dump? Many hook-ups require a 20 foot run with a bump up to accommodate the elbow connection into the drain pipe. Some drain pipes are above ground level exasperating the condition for good draining.
The point is simply this; with a 6 inch drop over 20 feet of slinky and then a bump up...causing back up and only the pressure of the tanks contents, would the results of the tests be basically the same?
Would there be so much left behind that only continuous filling and flushing could be performed to clean the tank?
Could this by why so many are aggravated in dump line ups? Straight pipes 2 feet up simply drain more efficiently than low valves with numerous elbows?
