rainsoft gold backwash stuck open

Just located an owners manual with more info thsn yhe one i have. Says foeign matter may be stuck in a valve...call dealer. Should i just call? Hate to pay for an expensive service call.

Could be a broken piston or seals and spacers are bad inside the valve body. Could also be a broken drive cam which i would not recommend trying to replace the drive cam on your own if not done correctly it could further damage the system.

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.
