"The Tankless Guys not only installed a new water softener system, they also put in a new tankless water heater and a new toilet. They provided excellent service. We had a range of options to choose from and Sergio and his team performed all the work in a timely manner. Sergio also answered any questions we had thoroughly. I highly recommend them!"

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

"The plumbers from Superior Plumbing were excellent. They replaced and rerouted water pipes, changing from galvanized to copper pipes. The sewer lines in our house were repaired. They also replaced an aging hot water heater. The technicians arrived on time, worked diligently through the day, and were efficient. We added on the sewer repair which added an additional day. All work was completed within four days. I am impressed with their knowledge and workmanship. The technicians were tidy and removed all our old materials including the hot water heater. I would recommend Superior Plumbing and Drainage Co without hesitation."

Water Softeners FAQs, answered by experts

Routine maintenance involves recharging the resin bed with salt or potassium, cleaning components, and periodic inspection.

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.

Water purifiers and water softeners serve different purposes, so the best one will depend on your particular needs. Water purifiers remove contaminants from water (such as bacteria, viruses, and chemicals), leaving you with ultra-clean and safe water. However, water softeners remove minerals from your water so that the water doesn’t leave stains around your house or cause plumbing problems.

There are several things that can shorten the life of a water softener. Homes with very hard water may have to replace the unit sooner because the water softener works harder to filter out the hard minerals. High water usage and infrequent maintenance can also put more strain on a water softener.

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.
