I have a culligans water sofetner system with a brime holding tank. My other tank is where the timer is and schedules the periodic recharging of the unit. I opened up the house after not being there for three weeks and my tank system will not go off of the recharge, it just sends the water to the drain and does not go into the holding tank. I think my tank froze while I was gone. Does anyone know anything about this and if it froze did it ruin my system?
