@H2O MAN,
We are renting a home with a similar set up. There is no bypass valve to the unit as a whole, but there are shut off valves for the tanks. If I want to bypass the softener, can I turn off the bypass valve on the second unit, the one with the controls?
Something is wrong with the softener and until it's fixed I don't know how to bypass the unit without shutting off water to the house.
Thank you.
