Because the park where we stay for 4+ months in the winter is frequented by donkeys every night, ; golf course grass, and river access. I picked up a length of pcv pipe with an inside diameter that will fully surround the Rino-flex sewer hose that I use. The donkeys at night and day time users of the area can see the white tube and not trip/stomp on the hose.
Ridgid pcv easy to support for drainage , 10' length $9. cuts with a knife any removed length can be re-inserted into the connector end if required for a different site.
Hose is also protected from UV rays.
