My grandparents put in a water softener in the 1960s. The softnend water in the house tasted horrible, so they would go to the back yard and use the water in the faucet for the yard to fill up the water jug in the fridge. It always sucked taking a shower at their house, it was impossible to get all the soap off of yourself.
We have pretty good city water here for the house.
I also have a water well I use just to water the yard. It is pretty hard water, but tastes fine. I had it tested for irrigation purposes and they said it was OK for that, just hard. I did not bother getting it tested for drinking as that is expensive, and I don't drink from the hose often.
Enjoy your soft water.
