in process of replacing the hose lines with rigid pvc. I already have pvc running from the filter to my pump and would like to put it at the rest. As you can see I also have a salt cell. Was considering using the single union ball valves instead. It says they are easier to use. I’ve read running a longer line coming out of the pump is best. Thinking of moving pump and filter over to align with skimmer basket. I see people putting their valves closest to the pool and others like me closest to the equipment. Also I want to add sacrificial anode as well for salt cell. I don’t know where to begin. And best way for performance to set up the lines. Are there any videos or pictures even that would be helpful. Do I need check valves for my set up? Where to begin.
