Claim 7:
8. A system for irrigation of a selected location, comprising:
a manual pump assembly having:
a pump barrel defining a pump barrel volume between a first barrel end and a second barrel end, and including a valve connection portion;
a plunger moveable within the pump barrel, and
a biasing system to apply a biasing force to bias the plunger towards the first barrel end;

a fluid source tube configured to fluidly interconnect a fluid source of a fluid and the pump barrel;
a tip assembly having a tip with an opening to deliver a selected material from the pump barrel;
a valve assembly configured to (i) be connected to the valve connection portion and (ii) control flow from the fluid source to the pump barrel and from the pump barrel to the tip of the tip assembly; and
a direction control grip member spaced apart from the manual pump assembly;
wherein the tip assembly includes:
a flexible tip tube extending from and fixed to the direction control grip,
a tip sheath through which the flexible tip tube extends and rotates relative to the tip sheath, wherein the tip sheath is configured to have a suction drawn therethrough past the flexible tip tube and directed from the tip while the fluid is expressed from the rotatable flexible tip tube, and
the tip axially held and extending from the flexible tip tube;

wherein the direction control grip member is rotatable relative to the pump barrel to rotate the rotatable flexible tip tube and the tip around an axis of the tip assembly;
wherein the manual pump assembly is configured to be reciprocally operated by a user by applying a user force to overcome the biasing force to move the plunger towards the second barrel end and stopping application of the user force to allow the biasing force to move the plunger towards the first barrel end.
