I have read the limited information and spoken to someone at HASA about it. It sounds good, but I was wondering if anyone has tried it on an AGP? The guy at Hasa said to use 2 check valves and install the unit between the pump and the filter. I don't see how I could do that since they are connected. We also have flex hoses from the skimmer to the pump and the filter to the return. He said the unit needs to be installed in PVC. I think we could figure out some kind of mod for that, but does anyone have any idea how it could be installed between the pump and filter?
