We bought our house 2 years ago and it came with a softener system, it has 2 cylinders (one bigger than other) and a seperate salt tank. We have noticed that lately it has developed a small drip from the top of the bigger cylinder where the settings are. It has a bypass that pushes in from one side, I pushed it in to bypass but it still leaks. I have also unplugged it. I have read that there are O rings that go bad and need to be replaced, but not sure how to get to them. I would like to try and repair myself, but need some guidance on how to open it up and see if there are some rings or washers that need to be replaced. I also don't know why it is still leaking if it is on bypass, is there still water pressure in it? Or does the bypass not work? If I could just stop the leak somehow and then just fix it at a later time, it would save us from wasting water. I am not familiar with these systems, it is our first. Is there directions or video somewhere that I can follow? Any help is appreciated.
