You need to know what is in your water softener. It all sounds good when you buy it but years down the line when you need work done to it, you do not remember what is in there. What type of media and what quantity of each is very important.
The good news is that water softeners are much easier to troubleshoot than they used to be, and while water softener repair can be challenging, with the right kind of knowledge, you can fix even the most common issues when your water softener is not working and get it back up and running in no time.
