[QUOTE="thesmithy, post: 46908, member: 427"] The design is set so that there is no delay in suction as on a yabby pump the plunger is at the bottom of the stroke.... the instant it moves suction commences.........the only delay will be in the length of any added tube. No material will be lost as it is a one way valve......any stopping or downward pressure instantly closes the valve ( not a couple of seconds) then the opposite valve opens discharging material from the side port. Nothing runs backwards what so ever. This I have fully tested.......6 " of 20mm tube as suction is not even worth mentioning. I personally do not use this as I do not crevice in the water. [/QUOTE]
