We're going on year 3 with our Intex 16x48 ultra frame pool, and are upgrading the pump/filter to a secondhand hayward power flow lx pump and micro star clear filter. We are running off an extension cord on a GFCI outlet. I saw bonding pop up. I'm assuming the hayward should be bonded, can the Intex be bonded (poles are coated so I'm not sure there would be good connection made around the top rail)? Does the bonding wire only ever carry current when something goes wrong?
