"The salemam put on an hour presentation so that I could see my bad water verses the filtered water. He was patient with me and most importantly he didn t act as if he was wasting his time and assume that I couldn t pay for the system. The system works great and I saw a difference immediately. The system was installed neatly and I although I initially inquired about the water system for bathing and washing only; I also purchased the reverse osmosis system for drinking water. They are pricey though."

"Totally amazing product. The first day it was installed, our cleaning lady called my wife asking what we did to the water, the difference was unbelievable. I did the install myself and Robert asked for photos during the process and walked me through everything as if he was standing in my basement. We could not be more pleased. Our well water is the standard in the neighborhood. While other people were talked into just a water softener, Robert told us we needed a iron remover from the water test he had us have performed. These folks know water!"

"I'm not a plumber so I can't absolutely say what I needed, but my property was dug up and my fence taken down to get the bobcat in. They left quite a bit of broken pipe and water bottles and their tape measure. The 2 men who were here 2 days were very loud shouting and playing and I hoped my neighbors weren't mad... sorryguys"

"When my water heater was going, I called them and they came out quickly to install a new one. I was worried it would be challenging to replace since it was in a tight space but they were able to work around it and now I donâ t have to worry about running out of hot water!

"When Dave arrived and looked at the faucet and where it was located - he told me that it would be an additional $50 to cut a hole in the drywall which I said ok.  Then he went down to the basement to look for the water connection and he noticed that I had an old disconnected water softener.   He mentioned to me to me that I should have this water softener removed because it should be  because it potentially could cause an explosion.  Then he replaced the faucet and I asked him to give me an estimate on a 50gal new hot water heater and he did, gave me a written estimate and said that they would replace all the connections and hookups and I thought the estimate was totally fare.  Then as he was leaving, he said that he was not going to charge me for the cut into the drywall, and I was most appreciative.   He did a great job and I will definitely have him come back again.

Water Softeners FAQs, answered by experts

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.

Yes. To get soft water, you can install a water softening system, which will replace the calcium and magnesium ions in the water with sodium or potassium ions. Water softeners cost anywhere from $200 to $6,000, depending on the size and complexity of the system. You can either install a water softener for the whole house or just at your shower heads. If you’re sensitive to sodium or potassium, you can install a salt-free water conditioner.

While it depends on how complicated the unit and installation is, it takes two to four hours to install a water softener unit, on average. It might take longer if pipes need to be replaced. You should make sure the installation area is clear of any objects that might get in the way before you begin.

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.

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.
