How can I power a small fountain/pump 50 ft from an outlet?
I am making a 25-30 gallon container water garden with a couple goldfish. I would like to have a filter/fountain in it, but where it will be is 50′ from the closest electrical outlet. A solar fountain is out of budget, so I would like to run an outdoor extension cord under the ground. Years ago, my Dad ran two 100′ unprotected outdoor cords between two houses and left it there for about 5 years without problems. But my situation is a little different. It will be underground, and it will be running almost constantly. Is this feasible? If so, how can I protect the plug at the pump? Electrical tape?
