Your video was very informative and I think I have watched it about six times now! I am trying to figure out the actual construction detail of the final bottle cap drain that leads back to the reservoir. I picked up the nestle waters cap with the spout built in. It does not move and there is another blue “cover cap” over it that you remove prior to drinking. Inside the hole there is a small “x” in plastic. IS THAT THE RIGHT CAP? I see that you fit the washer on the inside of the cap. Did you poke out the “x” and simply insert the tube and washer and got no leakage, or am I missing something? I am ready to put my system together. Also, on your video i saw the two “bulkheads?” punched into the reservior. One was the water feed tube that went to the pump, and the other was the drain (draining from two plant columns?) Did you put an additional water feed tube on the other side of the reservior that is not shown? So two water feed tubes and one “t” drain connected to both columns? Is this correct please? BTW, you have built an elegant system. I can’t wait to get it working. Thanks so much!!
I wait eagerly for your reply. I have all of my supplies and need these two questions answered and I am putting it together. Also love the clever cloth idea!
