EZ Hose Carrier/RhinoFLEX mod

I picked up Valterra, 64" EZ Hose Carrier and mounted it on my trailer so I could carry a longer sewer hose. The RhinoFLEX 15’ Sewer Hose and all the fittings, even a 5” Clear, Sewer Hose Straight Adaptor fits inside the carrier with just a slight modification to the 4” pipe thread on the end of the 4-In-1 adapter. If you have a lathe you can turn the outside diameter of treads so the adapter slides into the carrier. I don’t have access to a lathe so I used my belt sander to grind the diameter down. I put on leather gloves and let the adapter slowly rotate around my fingers while I pressed it against the belt sander. I would take a little off and the go and check the fit, once I had removed enough thread to fit inside the carrier I stopped, you need to leave enough thread to be able to screw it into the sewer drain. Using the belt sander as a lathe left the threads ragged so I had to go back with a thread file and clean them up as best as I could.
