"This is one of the most unprofessional companies I have dealt with. In June of 2021 GLP&H installed a faucet for me. That $200 faucet worked for 5 months before it broke. When I called to have it fixed in January of 2022, our plumber (Eldon) came out and explained they installed an old faucet in error. The old faucet was placed in a new faucet box which is usually sent out, however in my situation it was unintentionally installed. When Eldon took the faucet apart you could see it was an old faucet and he apologized and installed new one. Fast forward 8 months to August 2022. The new faucet has snapped. The company gives you a year warranty on the products they install. I called asking for a replacement since it's only been 8 months. I was advised the warranty had expired. How is that possible I just had it installed. Well ma'am when we installed the old one, your warranty started then so the new one we installed only had a 6 month warranty. I am sorry that is not how warranties work. I have been more then patient, especially after your people ADMITTED to installing the incorrect faucet, and now you are telling me you won't fix it because the warranty is expired. Absolutely not. When I called to talk to the manager, he was less then friendly and unwilling to make it right. I advised you I would purchase my own faucet and have your company install it you stated that wouldn't work for you. For a business that prides itself in being a family company you sure don't help your customers. I will await a response and a date when you can come install my new faucet."

Residential and business water treatment systems. Water softeners, UV lights. We will analyze your water for contaminants such as chlorine, low pH, iron, bacteria, and devise a system to suit your needs. Treat your water from the source, as it enters your home, so whether you are drinking it, cooking with it or bathing in it, your water is pure.

"The process was quick and easy. I just provided a water sample. It was determined that I had high levels of chlorine in our drinking water. I was able to solve my water problems with only one filter. Why did I wait years to have this done? Now I can be confident that our water is safe. Highly recommended."

FAQs for water softener service projects in Cassopolis, MI

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.
