How full should the water storage tank be?

I've built the Air and Water Power Tank (model 6), but I'm really not sure how much water to put in the water storage tank. The Air-Water Pressure tank is supposed to be half full, but I find it really hard to get to fifty pumps if I fill the water storage tank to even half. Any guidance would help. Thanks.

Hi David,

For models 1-6, I've found that the Water Storage Tank can be filled as much as 3/4 of the tank. The initial pumps will draw the water from the Storage Tank into the Pressurized Tank, once all the water has been drawn the remaining pumps will continue to pressurize the tank, this is evident in the air bubbles that enter the Pressurized Tank. Please note, the closer you get to 50 pumps, the shorter/smaller the pumps will be.

Ultimately, you can experiment with the amount of water that is being used as you'll see for the Water-Jet Propelled Models.

I hope this helps and if you should need further assistance, please contact
