got a generic hob skimmer with a jebo powerhead when i get it going i cant get any air to pull from the intake hose hose just fills with water even with the valve closed so is this a faulty pump or am i doing something wrong also if you put your hand close to the return when its on it pushes water into the airline and stops the oxygen flow
