Before you install your pond pump, make sure that you have access to an outdoor power point that has been installed by a qualified electrician. The power point needs to be close enough to the pond so that the electrical cable on the pump can reach it.
After the pump has been put in the pond, at the right height, turn it on to test the water-flow rate. If it's too high, the flow rate can be adjusted on the pump. Alternatively, you can attach one of the nozzles from the fountain kit to get the desired flow rate and the look that you want. Depending on the height of the nozzle, you may not need to sit the pump on a brick.
