Totally fine and i think i did you dirty. I must apologize and this is the first time i've seen this go south like this, helping many and having read half a bazillion of the same. 'Fill the pump' is only until that pipe. Either everybody else gives up quietly, or they understand already, but i TOTALLY see the flaw now in the common advice. The water level at that pipe is a foot above the pool. You are filling the pool down that pipe. You can overflow the pool and water will still go down that pipe until your whole town, and maybe a chunk of Iowa is the height of the water in the basket. Filling it only to the pipe is MUCH quicker.
