ABSTRACT:
A manually operated leak detection device used in locating fluid leaks in a ground surface includes an elongated rod and a handle transversely fixed thereto. The invention is improved by fixing an anvil on the rod; slidably mounting a first collar on the rod above the anvil; slidably mounting a second collar on the rod below the anvil; connecting and spacing the first and second collars by a pair of parallel guide rods passing through the anvil, each of the guide rods lying on one side of the rod; providing a protective sheath over the anvil, the first and second collars and the guide rods, the sheath being connected to the second collar; and slidably mounting a handle over the rod and a top portion of the first collar, the handle being secured to the sheath at the top of the first collar. The rod is manually and sequentially driven into the ground surface in the vicinity of the fluid leak by repeated forceful engagement of the first collar against the anvil without the need for a separate driving tool, and the guide rods and the sheath act to stabilize the rod in the area of impact between the first collar and the anvil.
