Just plumbed up a waterfall feature which is working nicely. The problem is that when I turn the pump off from the waterfall position, the filter backwashes into the pool skimmer. I'm not entirely sure why, and if I should be adding a check valve somewhere. And if so, where would be the...

Need to drain my pool. Only concern I really have is popping it out of the ground. Live in SoCal and hasnt rained a couple months. I only have a main drain on the pool floor, I dont see any other relief valves. I do have some mystery "valves"/things on the side of the pool under the lid...
