Just bought a Polaris 360 since we have no booster pump. My husband says it won’t work in our pool because it will restrict the flow to much. Anyone else using this model with success? He tells me that the valve restrictors have to come when the pool isn’t being cleaned to pump properly. I can’t imagine people are actually putting these things in and out all the time? Plus, it’s pretty highly rated, it must function with them in, right?
