Didn't know the best place to discuss this - but I wanted to share my idea for an inexpensive lightweight sewer hose trough.
Using a piece of 3" vinyl corner bead, I cut off the nailer tabs, and cut down a second piece so it slides into the first. It's 5' long when retracted....but it extends to 9'. I cut some velcro bands to hold the hose in the trough and prevent sag.
The main goal is to keep a a straight non-sagging hose (even under weight during draining) from the TT to the septic hole.
I have reached this conclusion after much careful thought and consideration. After reading through a lot of these posts and excellent ideas, we have a lot of talented and smart people on these forums! Many thanks to all for your input!
Joe - necessity (and a limited budget) is the mother of invention.... I enjoy the varied talent on here.
....and as it goes, looks like "we have winner" fitting everything into the 4" bumper (RhinoFlex, Sewer Hose Trough and Sewer Adaptor), . It still needs some field testing before the final stamp of approval....but I think it's going to work out OK.
