Tested it with my air leak tester and it wasn’t holding pressure so I then tested it with water and surprise surprise it’s leaking from where the tube res meats the pump head. I opened it and unscrewed the res tube from the pump head and was surprised there’s no O-ring sealing between the res tube and pump head. Seller isn’t helping at all no replies
This pump isn't working as it should be and the leakage is a prove for bad material and bad assemblage. Also the seller wasn't cooperative.
