Water Softeners FAQs, answered by experts

Hard water stains can be a headache because they will reoccur as long as hard water flows through. Thankfully, hard water stains are not permanent. With the right tools and an appropriate cleaning routine, you can prevent hard water stains from ever building up. However, you might feel like you are stuck in a constant cleaning cycle. In that case, you may consider hiring a contractor to perform routine cleaning.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

If your water softener repair is fairly straightforward, like a simple filter replacement, then you can probably do it yourself with little risk. However, anything beyond a simple fix should be addressed by someone with extensive plumbing expertise to avoid costly water softener problems, like leaks. 

That said, even simple problems can be complicated to diagnose, particularly if your water softener is attached to a whole-house treatment system. So, unless you feel absolutely certain that the problem is an easy fix that you can take on yourself, it's probably best to hire a plumber to diagnose and fix the problem.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

No. You should never directly drain a water softener into a sewer cleanout. This practice is illegal in many areas because it could allow raw sewage to get into your drinking water and make you seriously ill. Many places have codes requiring a specific seal, pipe, and a large air gap between a water softener and a sewage cleanout. Check out Florida's Plumbing Building Code as an example of what these restrictions might look like.
