The Benefits of Water Softeners

Water softeners are one of our specialties; in fact, we invented one ourselves, and it’s become one of the best in the business. Installing one is an excellent idea, since it: 

  • Can help you make sure your dishes are cleaner. 
  • Can reduce how much laundry detergent and dish soap you use. 
  • Can extend the life of your water heater and other appliances. 
  • Can reduce scale build-up. 
  • Can help your water taste better. 

At Marlin Plumbing Services, we specialize in the installation of water softeners, reverse osmosis water filtration systems, iron removal systems, and other whole house water treatment systems for your home. With over 40 years of experience in the industry, we are dedicated to helping you get the service you deserve. 

Water softeners are one of our specialties

In fact, we invented the first water softener in the United States to meet the plumbing code “The Eliminator” We sold over 60,000 systems across the country. The next generation equipment in 2010 was the Fusion XT equipment selling hundreds of thousands of systems. In 2020 We developed and introduced our newest generation of water treatment systems the Certiflow line of equipment. The new systems introduced the most advanced water treatment equipment in the world. Manufactured right here in Utah.
