a neighbor is about 3 weeks ahead of me in our respective builds with the same builder and just had his equipment pad finished up today. We're both doing salt water pools but noticed the PB put a Pentair in-line chlorine feeder (Rainbow 320 to be precise) in his install. Apart from possibly startup, is this going to serve any purpose? I suppose as a possible backup if his SWG cell goes belly up at some point before he could drop a replacement in?
