We were notified by Brunswick Water Company that we used 700 Gallons of water between 7:00pm - 7:00am. Rainsoft Tech came to check system. After changing a few washers he said it wasn’t the Rainsoft. He did find a bent u ring.
BTW we had a tech check system in July due to water spirts in the toilets and sinks. Water usage is back to normal after Rainsoft Tech left. @$150.00
Obviously it was the Rainsoft System.
