I have a Kenmore(sears) water softner that is about 7 years old. Over the past year it has been acting up and will not provide soft water. Lately it has been so bad that when you shower it feels like it stips all the oil from your skin. As before I looked into the softner and it is 3/4 full of water. Should I shut the bypass and let it run to drain water?? HELP:eek: :eek:
