Question:
Our kitchen sink has a faucet for cold hard well-water and another faucet for hot/cold softened water. We are replacing the sink and faucets and will add a reverse osmosis filter (and a faucet for the RO water).

Should we keep access to hard water? I am tempted to abandon it and just have the main hot/cold/softened and second RO drinking water.

If the dish-drainer is to the right of the sink, should I put the RO faucet to the left or the right of the centered main faucet?

Answer: That’s because they are upper Midwest US or Canadian tight asses :) and won’t buy a water filter or RO and are working under misconceptions. Try RO to make anything with, especially fresh brewed coffee, and you’ll be a convert Don.

And most well owners in North America with softeners don’t have hard water at their kitchen sinks.

We live in the city and have our kitchen sink cold side NOT run through the water softner. The primary reasons we did this are:

* Plants don't like soft water, so we can water indoor plants without going to an outdoor un-softened line.

* Fish don't like soft water so again, we can maintain tanks with water from the kitchen.
