Hi, I have a small pond with waterfall in my backyard. The pump stopped working. I have no doubt I can most likely fix the pump, the problem I’m having is I can’t find the pump. Can somebody please help me locate the pump or give me an idea where is at? There’s only dirt and a retaining wall behind it, I haven’t found anything on the sides. I’m assuming it’s in the water but I really don’t have a clue. Any help would be very appreciated. It’s covered in algae right now because the pump stopped. P.s. There are frogs or something in there so I don’t have the heart to put anything in it that may harm the animals. Thanks again
