So I purchased about 20' of silicone tubing a few years back and cheaped out and went with 5/8" OD from US Plastics. It's worked perfectly with the occasional kinking. This was only with gravity fed systems.
Last night I hooked up my chugger pump for the first time since i built my stand. The hose was getting sucked together at the inlet of the chugger pump, and I really noticed some kinking issues with the connections to the cam locks. (even with the 90 deg fittings)
I'm ready to bite the bullet and buy new heavier duty tubing but wanted to make sure this was my problem first. Does anyone else have this happen with the 3/4" OD silicone tubing? Has anyone else experience the same problem I have with the 5/8" OD?
