You could avoide the valve issue by using the same method used by the Simple Siphon products

I see a simple siphon attached to a ss racking cane. Slide that into a ss tube and pump up and down in the tube. No need for a super tight interference fit, just use the larger ss tube as a guide to reduce splashing. Just a thought.
Oh yeah, and like Revvy I like the idea of moving boiling wort to an HDPE bucket under a no-chill process. That would be awesome.

The simple siphon also has a light spring behind the marble to keep the marble in place just above the inlet. It really is a marvelous thing. I used it yesterday to drain my kids pool.
What do you guys think about copper pipe? Any reason why not?
I do have a design in mind that's one moving item, that won't have weight issues like the mentioned slug would/could.

dslater said:Great idea. I've been thinking about doing this with copper, but haven't gotten past the thought process. One question. What kind of tubing will you use to transfer hot wort? Can food grade tubing take those temps?
Golddiggie said:msexton, saw that, but I've also found 5/8" OD silicone rubber balls that could do the trick for a very low price. I would just need to order a pack to test with.
I'm not really sure what the final valve design will be, but I do know it needs to maintain a low cost, easy to get in the future, and such. So something that's made by one company is kind of out.
I might reach out to the place you provided the link to, to see what they can offer. Just not very hopeful that they can offer something that will do the job, without costing more than is reasonable. Plus, with my idea, I could include a couple of spare parts with the item so that the buyer won't need to worry about sourcing them later. IMO, not enough companies do that, for the cheap (and easily restocked) items.

Just based on history, or do you have an actual reason *why*?
I hope he proves me wrong.

Here's another thought, If the cost of making a "typical" total SS auto-siphon would be too high but people are interested in a 1/2" model for use with silicon tubing, why not make a hand operated peristaltic starter? It could just be a few wheels that are in a device you just grip and slide down the tube to start the siphon, spring loaded to disengage. Then all you'd need to provide would be a 1/2" cane with a tip. Easier to clean with fewer product contact parts. Might not work but just a thought.
