I recently was wondering how good my inherited water softener was performing so I bought some strips and tested the water in my house. The water was very hard, so I wanted to figure out what's up. The drain water from the softener is quite soft, so I'm now suspicious that I've somehow bypassed the softener.
The image in the link below shows the bypass valves configuration (red handles, bottom of image) for the softener on the right. My understanding is that this configuration should not only bypass the softener but also shut off water to my house. However, I've tried every faucet and shower head, all still work fine. I've also tried just hot water and that's also running fine.
Any ideas why I might still have water after these valves are closed?
