The folks at Scamp
chose to use a clear vinyl drain hose for the bathroom sink in our 2014 Scamp
13. Seems a good choice for making the complicated bends required to get the toothpaste, etc. to the pump feeding the grey water tank. But my DW complained about the mold, mildew, scum, filth, etc. clinging to the inside or the clear hose. I didn't really see this as a problem but immediately sprang into action upon hearing her disgust. Now a sensible solution would be to access the chemical shelf at my local retailer, add a brush or two and some good old fashioned elbow grease. Surely the vinyl could be brought back to crystal clear. But, calling on a skill I am not often known for (thinking ahead) I wondered how often I would need to repeat the cleanse. Not recalling any other clear drain pipes in my house or anywhere I decided to take an easier and more lasting course. Why not install an opaque drain pipe? Yet replacing the hose felt like too much work for martial harmony's sake. So I engineered a easier and better way. You can see from the attached picture the complicated, expensive and hopefully permanent solution I tried. That handy aluminum tape sold in RV stores, Amazon, etc. seemed the perfect, if Rube Goldberg, solution. After several months of use and extensive examination and testing it seems to be working quite well and my DW no longer mentions the foul sight. Harmony restored Scamping has returned to bliss.
Happy Camping, john
