DIY Auot-top off in 4 steps

[steva44]

What I do when i am on vacation or just as a top off.

20 L plastic container from my water cooler: free
3 feet of airline tubing: 1.50
a ballvalve: 4.00
refill the plastic bottle at RO H2O station 2 blocks from my house: $1.50

I put the bottle on my bucket of seasalt (so its higher then the sump) then I start a syphon from the plastic container to the sump, and set the valve so it drips a drop every second or two. l leave it behind the tank and make sure to seal off the big plastic bottle so it does not evaporate. For a few weeks you are set, as it evaporates the water drips slowly into the sump and refills it with premium water!

"making a tiny hole on top part in the milk jug for better flow"

this would cause the whole jug to empty, not to flow only when needed
