I wanted to buy extra tubing and was told that the size is diameter is 4mm and the wall thickness is 1.5mm. So I ordered 4mmx7mm tubing, but it was too small. I measured the tubing that came with my system and it seems to be around 5mm diameter and 2mm wall thickness. So it seems I should order 5mm x 7mm or 5mm x 8mm tubing instead. Is this correct?
Also, I have been having problems with the tube slipping off the cup recently and was wondering if there's anything that can be done about that. I'm going to try taping the area that the hose goes around to slightly increase the diameter, but I'm wondering if anyone else has had this problem. I was able to use the system for several months before this problem came about. I'm hoping getting new tubing will fix it, but if there are any other solutions...
