I have never had a water softener in a house before... and now I do. I use a lot of RO/DI. My question is this:
What will be harder for the RO/DI to purify (meaning the water that will shorten the life of the membrane and resins fastest), water with a lot of hardness (pre-water softener) or water with a lot of salts (post-water softener?
