It depends. Most softeners connect to your main water line. Some pros install them in one hour. Others… it’s a weekend project. But hey, DIY is cheap entertainment.

One rule: always install the softener before the tankless heater. Not after. That’s like putting sunscreen on after a sunburn. Pointless and painful.
Also, buy a softener big enough for your whole house. Tiny ones get overwhelmed. Your heater will throw a tantrum. Go big or get scaly.
What about maintenance? Do you have to feed it?
Your water softener is basically a pet. It needs salt every month or two. That’s it. No walking, no vet bills. Just pour in a bag of salt. Even you can do that.
Some softeners are “smart.” They text you when salt is low. Fancy, right? Others just sit there, quietly working. Either way, your tankless heater gets a permanent bodyguard.
