Jay. I used some old 1" galvanized water pipe as weight on my cheap plastic tubing. I did so because I THOUGHT that I would never pull the tubing out again, but that if I did, the tubing run through the pipe would not snag, so it would be easy to pull out...WRONG! It didn't snag, but every section of plastic tubing kinked between the pipes and I found out that my savings on cheap, versus weighted tubing was disappearing fast because I either had to repair or replace every time I moved it.
