Measure and cut a length of pipe to reach from the water source to the pump. Slide the barbed end of a threaded female adapter into the end of the intake pipe and secure it with a hose clamp. Thread a foot valve into the adapter and place it in the water, making sure it is not resting on the bottom.
Slide the other end of the intake pipe onto the intake barb of the water pump. Hold it in place with a hose clamp.
Slide a brass T-fitting onto the outlet barb of the water pump. Attach a pressure gauge to one end of the T, and use a male-male adapter to connect the outlet pipe to the other end. Use plumbers tape when screwing in the adapter and pressure gauge to the fitting.
Prime the pump and fill the intake line before turning the pump on. This will ensure that no air gets into the pump, which could damage the seals.
