Does anyone have a Polaris Raptor? I have recently purchased a new one & am having problems getting the right setting. It is connected to the skimmer. It will run good for a while & makes a ticking noise, but then it stops. You have to unplug & reconnect it to get back the same suction. It also seems to make one of the water outlets lose its prime and push out water softer. Is this normal? Are you supposed to change the setting frequently? Please help.
