"The street connecting mine was under construction at the time of my appointment and the staff of US Water Consultants waited almost an hour before being allowed to pass the construction in order to keep my appointment - that's great customer service. They were knowledgeable about my problem, gave me good tips on keeping my softener in good shape and only charged me for the replacement parts. I will definitely call them again if the need ever arises."

"They were very professional and did a fantastic job. They showed up on time, installed the system in a timely manner, spent extra time unclogging all pipes and faucets from the excess minerals. They arranged for the electrician to add extra plug sockets. They did a great job explaining the system and cleaned up after themselves."

"Brian responded promptly, was professional and courteous. He came right away to do an assessment and returned within a few days to install a new water softener system. He presented me with a lower cost option that could have been done same day but I chose to replace a 17 year old system with a new system that is more accurate (better monitors water use) and less costly to operate because it uses less salt. He performed several preventative maintenance updates: re-piped and plumbed in a new particulate cartridge, cleaned the screen on the radon system and replaced the solenoids, all within the cost of what other companies quoted for only the water softener replacement. The last technician that serviced our water systems (Radon & RO) rushed through the job and left them in worse shape than they were before he "serviced" them. Brian recognized the issues and fixed them. I will now be using H20inthe603 for all of my water treatment service. Thank you Brian for a job well done!"

"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs. They did have an opening for next day installation which would have been fantastic but I couldn't justify the additional $2400."

"I asked for a rep to come to give quotes for repair or replacement of my gas boiler. Before he came the old boiler failed, and Heritage was able to quickly install a new one so that we without heat and hot water for only a short time."

Water Softeners FAQs, answered by experts

Soft water is better for your hair. The minerals in hard water can dry out hair, make it brittle, and leave a film on the hair and scalp that may cause irritation. Hard water also doesn't rinse out shampoo and conditioner effectively, which can lead to product buildup that makes hair look dull and limp. You may also find you need to use more shampoo to get a good lather in hard water.

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.

The average cost to install a water softener, including the system and labor, is approximately $1,500. However, the total price can range widely from $600 to $6,000. For some complete systems, the cost may be between $800 and $2,500. Labor for the installation typically costs between $150 and $1,000.

The final price is influenced by several factors, including:

  • System type, capacity, and complexity

  • Home size and household water demands

  • Water hardness levels

  • Accessibility of the installation site and the extent of plumbing work required

  • Whether new electrical work is needed

  • The professional hired and any local permit costs

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.

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.
