"Brad came by to inspect our very old water softener that had stopped working. He determined it needed to be replaced and had a new one installed for us the following Monday. He was very informative and didnâ t charge us an arm and a leg. I highly recommend Maineâ s Best Water Treatment."

"Justin was professional and knew exactly what I needed to fix my existing water heater without trying to upsell me on a much more expensive tankless water heater. He had the relief valve and expansion tank in his truck and was able to install everything without issue. I would recommend hiring them for your plumbing needs!"

Water Softeners questions, answered by experts

If your ‘do isn’t doing what you want it to do despite using good hair care products, hard water might be to blame. Since hard water can’t rinse soap off as well as soft water can, your hair might grow limp because of the shampoo and conditioner residue that’s left behind. If you color your hair, you might see it fade more quickly or even turn a different shade as the dye reacts with the minerals in the water. You might also experience an itchy scalp, thanks to the dryness that comes from bathing in the hard water.

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.

While not everyone can detect taste differences in high-calcium water, water that has a slightly metallic taste probably has too much calcium.

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.

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.
