Don’t do what Dave did. He pointed the discharge hose straight onto his driveway (bad) and didn’t check the flow rate (worse). Always route the brine to a drain, a dry well, or at least ten feet away from your foundation.
And please don’t water your lawn with it. That salty water will turn your green grass into a crispy, brown apology. I know it sounds like a waste, but that water is not friendly to plants.

Can You Reduce the Flow?
Yes, actually. You can adjust the regeneration frequency and the brine fill amount on most controllers. But here’s a secret: if you have really hard water, you’re stuck with a certain minimum. It’s physics, not a conspiracy.
Also, consider a “counter-current” or “upflow” softener. They’re pricier, but they use up to 40% less water per cycle. Your wallet and the planet will thank you.
