Setting up a pond waterfall pump system must be done carefully to ensure maximum water flow. Not only will this improve the appearance of the water garden and the quality of the water, but it may help reduce energy costs by reducing leaks and waste.
Choose the correct waterfall pump system for the size of the waterfall in your backyard pond or water garden. The pump must be strong enough to move 100 gallons of water per hour for the thinnest trickles of water to 500 gallons per hour for wider and faster waterfalls.
Screw a hose to the water outlet opening on the waterfall pump. This is usually a threaded connector designed to attach to a garden hose easily. If it is not threaded, use a sturdy, non-collapsible hose and a plastic hose clamp to attach it tightly to the pump. Do not cut the hose length at this time.
Build a sturdy spot for the waterfall pump system to rest in the existing pond. A couple or bricks, rocks or an overturned terracotta flower pot can all work well. Setting the pump system off the pond floor will help prevent debris from flowing into it and causing clogs.
Use a hose in a similar fashion to attach the waterfall pump to an in-pond filter. If you are using a waterfall filtration unit, this step can be skipped. However, using both the pond filter and a waterfall filter system can help keep your pond that much cleaner. The waterfall filter will also keep the falls themselves from becoming clogged with detritus.
Place the pump in the pond so it sits upright, and lay the outlet hose so that it comes out of the pond near the waterfall. Lay it along the structure of the waterfall and attach it to the waterfall container if you are using one. This will also have a threaded connector. If you are not using a prefabricated container for your waterfall, position the end of the hose at the top of the waterfall pointing toward the pond. Conceal the hose with rocks or plants.
Turn on the waterfall pump system. It may take a few moments for the pump to fill with water and get water to the top of the waterfall. While the water is flowing, use a garden hose to fill the water garden or pond to the correct level. Be sure to keep the pond well filled so the waterfall always runs properly.
