We had a warm spring here in AZ and thanks to my solar cover we started swimming a couple weeks ago. The pool has quite a bit of fine dust settled in it from being unused all winter and I thougt I would sweep it by the main drain but the dust just floated past the drain. I looked up how to adjust the flow from the drain and saw that there should be some valves before the pump to control how much comes from the main drain and how much comes from the one skimmer I have. But here is what my plumbing looks like:
Is this normal? How can I get my main drain to pull some of the water to the filter?
