I had this idea when I was reorganizing my equipment in the cellar about keeping plastic tubing straight. I HATE the memory in tubing when I'm trying to rack that makes it so I never get all the wine out without disturbing the lees. I originally looked for a way to hang my tubing with weight to straighten it but couldn't find a good way. Then I thought of this...
This consists of 3/4" PVC tubing cut to a length of 24 5/8" with a cross put on the top to hold it onto the demijohn. Everything is held in with friction, not PVC cement. The tubing is first inserted into the PVC pipe at the cross, then the anti-sediment tip placed on the other end.
One of the problems is that the middle part of the bottom is not the lowest point. The nice part of my system is that the plastic tubing can be adjusted in or out to reach the sweet spot in that groove. (See picture 2)
I also noticed a problem with the anti-sediment tip. (See picture 3) I then cut 2 channels into the PVC to reduce friction loss through the opening. I use a Superjet filter as a transfer pump but there's no reason to put unnecessary strain on the pump motor when it can be avoided.
I'm open to suggestions here, will PVC have any adverse affects in my wine even with short contact time? What about the ink that they print on it? Should I sand it off or am I opening the door to bacteria hiding in the scratches? I hope this helps some of you guys out there if you like it!
