"Both the salesman and the tech were fantastic. From explaining the benefits and the cost, to installing and actually making the plumbing system better, they did a fantastic job. The technician had some health issues he needed to see a doctor about, but he and the salesman returned later the same day and finished up the job perfectly. I can’t recommend them more. Oh, and our water is so much better now!"

Water Softeners questions, answered by experts

Installing a water softener could help reduce calcium buildup in your pool if your pool has high calcium hardness as a result of hard drinking water in your home. Pool softeners work by exchanging calcium and magnesium for sodium, so if you use softened water to top off your pool, it may help keep calcium hardness from rising over time. However, it won’t lower the calcium hardness of the water already in your pool and isn’t a practical way to control pool calcium levels. The average water softener installation cost is between $200 and $6,000.

Some shower water softeners are effective, but this isn’t always the case. Most shower filters only filter out chlorine, not hard minerals like calcium. Other shower filters can't handle the demand in homes with very hard water. It's also important to change the filters on your shower filters. Failure to regularly swap out old filters will make the filter ineffective over time. 

The primary difference between a water softener and a water filter lies in what they remove from the water. A water softener is designed to remove hard minerals like calcium and magnesium. In contrast, a water filter has a broader effect, removing various contaminants above a certain size, which can include bacteria and other impurities.

To decide which you need, consider your goal. If you want to eliminate hard minerals, choose a softener. If you want to remove a wide range of contaminants, a filter is the better option. Filters are also generally less expensive to install. Depending on your water supply, you may need to install both for comprehensive treatment.

No, a water descaler won't descale pipes. The charged water running through the pipes may very slowly dissolve mineral deposits and hold them inside the water, but it's a very gradual process. If your pipes do need descaling, it's much better to get a local plumber to descale your pipes.

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
