Build your own Garden Waterfall using a Low Voltage 12 Volt Pond Pump and your Landscape Lighting System.
We were installing a low voltage lighting system in our front garden and decided to add a waterfall to the garden using two pots that poured into each other. I set up the two pots with one on a higher level than the other. The bottom pot was filled with water and the plan was for a bilge pump to pump water from the lower pot to the upper pot until it spilled back into the lower one. We did not want to run 110 volt wires for the pump out to the garden since this would require an electrician. I wanted to use the 12 volt landscaping wiring that was already there. When I tried hooking a 12 volt bilge pump up to it it just vibrated and would not pump. This was when I discovered the difference between a DC and an AC pump and AC and DC power.
After a little research I learned that a landscaping light system puts out 12 volts of AC power whereas a car battery puts out 12 volts of DC power. A DC boat type bilge pump will not work on an AC system. This may be obvious to most people but it baffled me. When I went to find an AC pump I found that they were not available locally. However, several companies on the internet carried them. I purchased a Fountain Pro 12 volt AC pump, dropped it into the lower pot full of water, ran a hose from the pump to the top pot, clipped the wires into my low voltage wiring system and turned on the power. Instant Waterfall. It has worked flawlessly ever since.
AC landscaping power systems are safe and do not require an electrician. They are designed not to shock you. To install one you simply plug the transformer into a 110v power source and then run the 12 volt wiring into your garden. I run several lights and my waterfall off of one 200 watt transformer. The wires and lights can get rained on and even submerged and it does not seem to affect the system at all. The same pump can be used to create a fountain or water features in a small pond. The ideas are almost limitless. And all without having to run any high voltage wiring into wet areas.
