I have pro 5 too but the Ionic pump from them is an aquatec pump and half the
price elsewhere fitting is easy 2 wires red/ black 4 nuts, 2 quick release water
fittings but imo use a shurflo or flojet but also one of the reasons my pumps went ..... up is pump controls that got wet from being poorly positioned on control panel we have now moved them where they don't get wet, like just inside the back doors high up all in all its one of the easiest jobs to do
