Hello Everyone - I have a stenner pump that will not draw the liquid to pump. The liquid is in a 5 gal carboy and the pump is about 1 ft above that. I am using Teflon taped threaded connections to connect to the pump tube. I am using a #1 tube. The pump will draw liquid if I raise it above or close to the pump head. When I put the container back down I see a bubble appear on the liquid entrance side of the pump. The liquid is being pumped downstream from my filter so it is on the low pressure side. The threaded connections connecting to the pump tubing have 1/4" quick disconnects on the other side. I am using 1/4" OD polyethylene flexible tubing in the push quick disconnect fitting. What are your thoughts of this type of connection? Do they leak a little air? Is there a change that the pump is not totally self priming with the smallest tube in the pump head? This would also mean I cannot count on the dosing rate.
