"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!"

"Very well. The housemate using it likes it. It works well and is a great improvement over the old, leaking and very noisy one. Will definitely have more work done in the house, as needed."

Water Softeners questions, answered by experts

A good hardness level for drinking water can vary based on personal preferences, but an ideal level is 3.5 to 7 GPG. This means your water isn’t soft or hard. However, some people prefer the “fresh” taste from the minerals in hard water, while others like the smoother, “slippery” texture of soft water.

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.

A water softener removes minerals from your drinking water and can make your house water softer. These softeners are designed to extend the lifetime of your plumbing system while also making water safer and more palatable for drinking. Hard water, which is water with a heavy amount of suspended particles, can also cause hair damage, skin irritation, and buildup in your pipes.

You can install a water softener system by turning off the water supply, draining the water, and then connecting your device to the waterline. Next, you’ll fill your tank with the recommended amount of salt or brine (whichever your unit calls for; be sure to read the instructions). Turn the water supply on and check for leaks. You can opt to let your water run for a few minutes, then test it using strips. 

The process of inspecting your water softener system is similar.

Softener systems extend appliance life spans, improve skin and hair health, and reduce pipe buildup by removing minerals like calcium and magnesium.
