Pump did not work.
The pump did not work. Did not hold the pump. I pumped very fast 4/5 times and before I could remove the hose the suction deflated. I had an identical pump from a few decades ago. Different company bit identical pump. This pump lasted me over 20 years. then finally it quit working. In the process of returning this pump. There could actually be a hole in the tube. I'll buy something else. Shipping and customer service was excellent.
