out with old and in with new.
Pipe size difference and height of it caused a little rework but not bad. Water taste is getting better or I’m getting use to it. But all in all it’s good.

Questions

AquaOx WS (Water Softener), specifically

The questions we hear most about this exact product.

Will my water taste salty?

No. Softeners add about 30 mg of sodium per 8 oz glass, eight times below the human taste threshold. On a strict low-sodium diet, pair with our under-sink RO at the kitchen tap.

What kind of salt do I add?

Standard solar salt pellets from any hardware store. Around $8–$12 per 40 lb bag. Avoid rock salt (too dirty) and table salt (too fine).

How often do I refill it?

Once every 4 to 8 weeks for most homes. Check the brine tank when you swap your HVAC filter, if it is below halfway, top it off.

Is this different from a salt-free system?

Completely. Salt-based softeners physically reduce calcium and magnesium via ion exchange. Salt-free systems just change the crystal structure so minerals do not stick to pipes, they do not soften water.
