"We owned a 17 yr old water softener that was no longer working. Rantz offered 2 options, he could fix the old unit or install a new one offering the additional benefit of a full water purifying system. He was excellent to work with at a great price so we chose new. We are so glad we did. Nate did the installation very professionally, went over the instructions on use & cleaned up. Rantz & Nate are so nice & wonderful to work with. We highly recommend!!!!"

"Joe was so kind from the start. He was able to come out quickly to evaluate if our previous water softener was able to be repaired or replaced. We had gotten quotes from 5 companies and Joes pricing was the most reasonable for the equipment and quality of work. Once we decided to go with Haven H2O they were able to fit us into their schedule within a week. We havenâ t needed to call for concerns but Joe let us know we could reach out anytime for concerns. Not that I look forward to any future plumbing problems, but if they do arise itâ s comforting knowing there is a knowledgeable and reasonably priced professional nearby."

"Billy and his team did an excellent job of replacing everything with the water system. Upgraded well pump and pipes, replacing pressure tank and water heater. Added filtration and water softener systems as well. Replaced kitchen and bathroom faucets,also both frost-free hose bibs outside. Very professional friendly team. Cleaned up work areas very good. Would use them again in the future as well as recommend them to anyone who needs plumbing work done."

"This company did a phenomenal job! They replaced our main water line, and did excellent, quality work! They were prompt, they were prepared for COVID, they also put drop cloths down so that they wouldn't dirty the carpet! They took extra care not to mess up the yard by putting down plywood too. They were efficient and did a marvelous job. I highly recommend them and would definitely use them again! One of my neighbors used them for indoor bathroom plumbing repair and said the same thing. They are also reasonably priced!"

"Martini Plumbing Provides me with superior service. Technicians Rob and Dan took the time to ensure I understood what needed to be done. They went the extra mile to work with my insurance adjuster and restoration company. They made a stressful situation easier to deal with. Went the extra mile and worked late to ensure we had working plumbing and hot water."

Water Softeners FAQs, answered by experts

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.

Replacing a water softener costs $200 to $6,000, depending on the capacity of the water softener, the type of water softener, and the amount of people living in your home. An ion exchange water softener is the most common type and costs $500 to $3,000. Water distillers, which cost $1,200 to $4,000, and dual-tank models, which cost $1,000 to $5,000, are definitely pricey, but they offer more filtration or capacity, respectively.

Experts recommend that you put two to four bags of potassium chloride in your water softener every month. This amount depends on how much is in the bag (40 pounds is most common) and what your water softener manufacturer recommends. For more specific advice, talk to a water softener pro in your area and read the manual that came with your system.

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.

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.
