Okay so I decided to do some tinkering today. I know I can get a cheap inexpensive Aqua Lifter pump for $15-$20 to do this job for me. Where is the fun in that, when I can build something out stuff I already have around the house? Anyways here is the bill of materials: 1. Air Pump - Common Aquarium air pump 2. Water Container - (I used a 2 liter bottle for this build) 3. 1/4" Rubber Airline Tubing 4. 3/16" Rigid Airline Tubing Here is the tools needed: 1. Knife 2. Drill 3. 7/32" Drill Bit First off I drilled 2 holes in the cap of the 2 liter bottle. I made sure to leave the rubber piece in the cap to ensure a better air tight seal, when replacing the cap. Next I cut my rubber airline tubing into 2 pieces. One piece to reach the air pump and the other for a drain line. I then took the rigid airline tubing and cut a piece about 1/2" long and a piece that was the height of the bottle. Next I pushed each piece of the rubber airline tubing into each hole. After that I inserted the 1/2" piece of rigid airline tubing about 1/4" into the rubber airline tubing that comes from the air pump, and I inserted the the long piece of rigid airline tubing about 1/4" into the rubber airline tubing used for the drain line. I then pulled the rubber tubing back through the cap until the rigid tubing was came through the top of the cap. This created an air tight seal that I did not need to glue or silicone. Next I filled the bottle up with water and screwed the cap on the bottler hand tight. I then connected the rubber tubing to the air pump and then turned the pump on. Result: Water flowing out of the bottle at 10gph, and when I turn the power off it takes about 30secs for the water pressure in the bottle to equalize and stop the water pumping. This will be used with a DIY ATO that I plan on building for my sump. A big plus to this is, the electricity is completely separated from the water. I hope you guys enjoyed my little DIY project..
