"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"My boiler was not working. I had a company come out and say that it was so old and carbonized the best bet was to replace it. I called other companies who either refused the work of attempting to fix and clean or suggested a full replacement. Upon recommendation of my realtor, I called Franco Belli Plumbing. I spoke with the manager there, Manny, who after seeing photos of my boiler, insisted he could fix the boiler. And fix it he did! Manny knows what he is doing, he's like a boiler artist, a Mozart of heating systems. He just gets it. My boiler is up and running perfectly, and judging from the way it looked on the inside before and after - is running even better than it was before. Such fair pricing as well, after a lot of researching and calling around - Manny did this amazing work and saved me from using another company and their easy way out of installing an entire new boiler at $5K when I could get another 10 years out of this one. Don't hesitate to call Franco Belli Plumbing & Heating! Manny is the best!"

"Antonio, at Greenovative, was great. I really enjoyed his professionalism. He and his crew found creative ways to decrease the price of the project. We are happy we gave Greenovative this project. Honestly, we will use them again."

Water Softeners FAQs, answered by experts

The most accurate way to determine whether you have hard water is to purchase a water test kit from a hardware store or send a tap water sample to a lab. But there are some signs you can look out for without professional testing. For instance, if you're consistently dealing with mineral stains on your glassware, windows, and shower doors, you're likely to have hard water. Hard water can also make it harder to lather and rinse soap, so if you're struggling to work up a good lather in the shower, hard water might be the culprit.

Yes, you can have both a water softener and a water filter. In fact, some manufacturers sell dual water softening and filtration systems that treat hard water and provide clean drinking water. If you’re unsure about what you need or want to discuss your options, reach out to a local water softener installation company.

The main difference between a water softener and a water filter is what they remove from the water. A water softener is specifically designed to remove hard minerals, while a filter removes a wider range of contaminants above a certain size, such as bacteria and other impurities. If your primary goal is to remove minerals, a softener is the best choice. If you want to remove various contaminants for safety or taste, a filter is more suitable. Filters are also typically less expensive to install. Depending on your water supply's specific issues, you may need to install both systems for comprehensive treatment.

Whether you need a permit or license for a water softener installation depends on your location, as requirements vary significantly. Some municipalities require the installer to hold a plumbing license, some mandate a permit and an inspection, and others require both. In some areas, no special permit or license is needed at all.

To determine the rules in your area, you can contact your local building department or consult a local water softener installer or plumber. Often, only certified professionals are authorized to pull the necessary permits, and they will typically handle the entire permitting process for you. Regardless of local laws, it is always recommended to hire a licensed professional to ensure the system is sized and installed correctly. You can use Angi’s state licensing tool to check an installer’s license status.

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.
