3/16" tubing: Limit on distance from last tap hole to tank?

[David in MI]

I apologize if this has been asked/answered before....

I'm planning to swap out the vast majority of our tubing from 5/16" to 3/16" but am wondering if there is a limit on the distance between the final tap hole and the collection tank. I think the longest run would be potentially close to 200 yards, maybe a bit more. I attached a satellite photo but couldn't tell if it will be large enough for you all to see it. If not, I'll upload it to photobucket.

On the attachment, the blue dot in the upper-right corner is the proposed location for the collection point. The two green dots represent the final tap farthest from the collection tank. I hope that makes sense.

There is no limit to the length. Put another way, length is immaterial in vacuum generation in 3/16" line.

That's what I thought and hoped but thanks for the confirmation.

How is tension on the tubing maintained between the last tree and the tank?

Use another tree or the tank if it's heavy enough and attach hollow core braided rope. It will act like a Chinese finger trap and hold it tight. For 3/16 tubing you'll probably need 1/4 inch rope or a little smaller if you can find it. Run the tubing through the middle of the rope for about a foot to get it to hold well.

After the last tap I zip tie it to the 3/4 inch mainline until I've lost the 30' elevation then it saddles into the mainline. I also have a section of woods with no mainlines, The 3/16 is zip tied to a 14 ga. wire after the last tap and runs straight to the tank on it for 500'. I have two 3/16 lines configured where they run on the wire, about 25-30 taps on each.

I just side tie to any tree I pass.

thank you. I will try all the suggestions based on my tank location
