I learned the hose from my macerator could develop small holes in it from laying on the gravel. Those little stones can be pretty sharp, as you know if you've ever gone out barefooted. Anyway, the pressure of running water and weight of the water in the hose can wear the hose out prematurely. I took a 1 1/4 PVC pipe and cut it lengthwise. I put it down first and lay the sewer hose inside it. If the run is short enough I use the other half to cover it and secure them with a couple bungee cords. Quick, easy and looks good. A side note is while visiting the Grand Canyon, they suggest you don't leave your sewer hose out at all because the Ravens love to peck holes in them.....Dennis
