The pond is probably 80 + 100 feet.the punp is being put in the middle of pond to circulate the water.It will have a fountain type hose on it.I plan on getting 14/3 sjtw cord and put it in pvc from my gfi to the bank of the pond ,and then lay it on the bottom of the pond till i got to the pump.The pecker head has a rubber gasket on it ,and the motor it self is sealed,i plan on using marine grade sealer to seal pecker head.
