Does water softener installation require a license?

<div><p>The license requirements for water softener installation depend on your location. Some municipalities require that the installer hold a plumbing license, some require a permit and an inspection, but no license for the installer, and some require a permit and a license for the installer. Regardless of the local laws in your area, it’s always a good idea to hire a licensed plumber or installer. These pros will install your system properly and have the experience to size the system appropriately. Use Angi’s <a href="https://www.angi.com/angi-license-check.htm">state licensing tool</a> to check your installer’s license status.</p></div>

How big of a water softener do I need?

<div><p>Your water softener size is based on your total household water consumption. In most cases, you can assume the average household member will use around <b>75 gallons per day</b>. Multiply that by the number of people in your home, then multiply by 10 (for the typical grains per gallon). You’ll get a number in grains that should help roughly size your water softener. However, it’s best to hire a professional to install your system and use more exact numbers, like your exact average water consumption per day and starting water hardness.</p></div>

"Very fast reply and prompt service. Knowledgeable about heat pump water heaters and insulation cost reasonable compared to other quotes. Punctual and quick install. The only problems were that they did not bring a long enough hose for a condensate pump and left the pump hook up in a partially finished state, said they would return to fix but have not contacted me to do so. Also they said I would need to make another appointment to return to remove the old gas pipe that went to my old heater instead of just taking it at the time."

"If I could, I would give this horrible service provider a 0.0! I scheduled a plumbing appointment on a call, which was confirmed via multiple texts the day prior to the appt. Then had an employee go to the location during the 4 hour window they specified and wait for the plumber. On the day of the appt, 1 hour into the time window someone calls and says, sorry we’re not going to go because we only do residential plumbing. This was a surprise, as it was communicated to them that this was a business when I had set up the appt. So, I decided to speak with a manager. After spending over an hour of being bounced around from one dept to another, asking for a manager, they never connected me to one and their dispatcher had the audacity to say “sorry for your inconvenience, but you’ll just have to find someone else.” WOW! The hoops they make you jump through and the rudeness is not worth the hassle. I would definitely recommend you find a different plumbing pro for your project!"

"They installed a minisplit cooling system, with 3 exchanges June 2021. Since then it is not operating the way it should. In my bedroom with the door closed at night on cool at 70 degrees the humidity goes up to 80%. I wake up uncomfortable, change it from cool to dry mode. The humidity will go down into the 50% range but the temperature drops down to 62 or less! So in cool or dry mode I can't get a good nights sleep! They come and look at it and tell me everything is fine. I'm going to buy a window air conditioner tomorrow which seems insane because i spent $10,000 on this minisplit AC system!"

FAQs for water softener service projects in Plainfield, NJ

The license requirements for water softener installation depend on your location. Some municipalities require that the installer hold a plumbing license, some require a permit and an inspection, but no license for the installer, and some require a permit and a license for the installer. Regardless of the local laws in your area, it’s always a good idea to hire a licensed plumber or installer. These pros will install your system properly and have the experience to size the system appropriately. Use Angi’s state licensing tool to check your installer’s license status.

Water softeners are worth the money if you live in an area with hard water. Hard water is safe to drink, but it poses serious threats to your plumbing system. The minerals in hard water will gradually build up on the inside walls of your pipes, reducing water flow to your fixtures. The minerals can also gradually corrode your plumbing system, reduce its lifespan, and increase the risk of leaks. Hard water also makes soap and detergent less effective. Water softener systems can solve all these issues, making them a great investment.

It’s possible to install a water softener yourself, but we don’t recommend it. Water softeners require working with copper pipes and electrical wiring, neither are suitable tasks for most DIYers. Plus, working with water and electricity together is dangerous and could pose a risk to your safety. Water softeners also need to be calibrated so that they don’t make your water too soft, as soft water poses just as many risks as hard water. Overall, it’s well worth hiring a local water softener installer to place your water softener system.

The cost to install a water softener system is $1,500 on average, ranging between $200 and $6,000. The labor for water softener work typically costs between $150 and $1,000, so you can add that to your equipment costs to get an accurate total. Your price will depend on many factors, including the following:

System capacity
Home size
Water hardness levels
Type of water softener
Presence of electricity in the installation area
Local permit costs

Your water softener size is based on your total household water consumption. In most cases, you can assume the average household member will use around 75 gallons per day. Multiply that by the number of people in your home, then multiply by 10 (for the typical grains per gallon). You’ll get a number in grains that should help roughly size your water softener. However, it’s best to hire a professional to install your system and use more exact numbers, like your exact average water consumption per day and starting water hardness.
