We have 2 pumps and it was so funny, there was one already installed but its not too powerful so I bought another to help empty the big pond quicker and water the plants with the water, well I made a water feature from half a whickey barrel, had to fiddle with the pump to turn it on and got absolutly drenched, the new pump is very powerful....the pond we have would look nice with a formal concrete feature, no money to spend on a pond just now but I keep thinking ways I can make a feature, as I say, there is a pond in place with a switch in our garage so no probs!!
