"Ralph and Peter did an amazing job fixing the issue with our kitchen sink not having cold water. They were both very patient and shared knowledge with me so I could learn more about the issue at hand and about the water control in my home. I will be using them again for my future plumbing needs and I highly recommend their services!"

"NMP was not the cheapest estimate I got for my water treatment system, but I'm very glad I went with them. Ultimately, the job required updating my well pump and head in addition to the planned updates to the in-house treatment equipment. Not only was NMP great at their job, but the well contractor they worked with did excellent work as well. There was a minor issue with the initial installation of the water softener tank that caused some of the softening media do come out of the tank but the issue was addressed completely. It's been about 6 months since the work was done and I continue to have great water quality and pressure coming into the home."

"Travis and Elvis were very professional on the phone. Travis provided detailed information and answered all of my questions to better help me understand between options when I was choosing a new water heater for my home. Travis provided me with a free estimate and stayed within the price range we agreed to when completing the job. The water heater was installed in a timely manner. I also received a follow up phone call to check how the water heater was working and if I had any questions which I appreciated. I would definitely recommend hiring this company and plan to use them again in the future."

"Offered options: purchase another like it or purchase one from Advanced. I told them to go ahead and put one in. They put the old one back together that day, came back in 2 days, removed old one, installed new one. Haven't priced water softeners in years so no idea if price was good but seemed reasonable. Quick, neat clean-up, great machine. Couldn't be happier."

Water Softeners questions, answered by experts

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

It’s not a good idea to oversize your water softener. Doing so will mean the tank doesn’t get full, which can lead to channeling. This leads to a large portion of the resin beads not being utilized and the beads at the bottom of the tank being overused. Over time, this will reduce the efficiency of your system, not to mention that the upfront cost of an oversized softener is unnecessarily high. If you have a timed regeneration cycle rather than a demand-based one, you’ll also spend far more on replacing salt than you need to.

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.

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

You should not use a water conditioner with a water softener because a water conditioner changes the chemistry of the water and causes the ion exchange in a softener to be ineffective. Choose a water softener if you have hard water or well water, and use a water conditioner if you need to remove certain contaminants.
