Here’s the first real step: locate the bypass valve. It’s usually a red or blue handle, shaped like a tiny spaceship. Turn it so the water bypasses the softener entirely. This is crucial—you don’t want to re-plumb your house with a mudslide of regrets while fiddling with the controls.
I once skipped this step and learned that hard water under pressure will shoot across the room like a fire hose at a frat party. My cat still glares at me from the ceiling fan. So, find the bypass, twist it gently, and let the house run on normal water for a few seconds. You earned that small victory.
