Extremely overpriced for what is! Needs redesign and price drop. Seems to be a common problem

I bought this back in Jan of this year and finally got to use it when installing 2 new Black Berkey filters. That's when I realized how overpriced this item was. Thank goodness I am pretty good at fixing things and devising solutions to problems. Basically, fixing other people's/companies' poor/cheap designs. After figuring out the right way to assemble this pump, I used it on the first new filter. All I got was a lot of air mixed with some water. I thought at first that this was just the air contained in the new filter element that was being "expelled" and replaced by water. After a time, I realized this was not right and looked for the problem. About this time, the plastic tube between the plastic filter adapter and the one-way inlet valve came off of the valve and would not reseal. To fix this, I resorted to a small spring clamp, that you operate with pliers, to fit around and seal the tube to the valve. On the next try, I was still sucking air, so I looked for another problem. This time, after completely submerging the filter in water past the plastic adapter, I discovered that it was the adapter leaking air around the threads. No matter how tight I got the fitting, It still sucked air. I solved this by wrapping some teflon tape around the threads on the filter and the problem was solved. My take away....this is a high priced, poorly designed device and Berkey should redesign and upgrade it. How??? Pre-assemble these using longer tubes and spring clamps on the one-way valves. OUT of space to continue!!!
