    it's 8.3 pounds per gallon. but the issue is pressure exerted on the stoppage. not what the weight of the water is.

    every foot of head is approx. 1/2# (.43#)
    the more head, the more clog busting pressure. a 10' head is the same pressure at the base of the stack weather it's a 1/2'' pipe or 6'' pipe.

    now weight of the water on the hangers is a different story. total weight of 10 gallons would be 83# plus the pipe weight.

    i know from experience that a stoppage at the base of a hill is going to be a miserable stoppage. any stoppage that can hold back a 30'-50' elevation change/ head, is not a simple job. for this i break out the jetter and let it work on the roots. this way i don't have to fight a downhill stoppage with a heavy cable and gravity.
