Never had an issue before and now start to feel a little tingling on my hand when my Polaris Booster Pump is on and my hand is on the pavers around the pool. Nothing has changed except that I moved some pool furniture around. Does aluminum pool furniture need to be bonded somehow? Also, where should the copper wire end? Should it be a continuous loop around pool? My wire ends connected to an old gas pipe where a heater used to be. Is that normal? Thanks, Tom
