Reviews for Culligan of Merrillville and St. John

Overall rating: 4.8⁄ 5

  • Noreen Cook

    We finally decided to make the investment into a whole house water softener and reverse osmosis. After researching our options, we chose Culligan Water. The two main reasons we went with Culligan were the reverse osmosis button which eliminated the need to drill a hole in our countertop and the 10 year warranty. The process was super easy and we were able to have the install completed 4 days later. One more perk of Culligan is the salt drop off. We were able to sign up for automatic delivery so I won't worry about running out of salt.

  • Allison Rosinski

    Super nice staff who were very helpful to my husband and I as we just moved into a house with a well after having had city water our whole lives. The man who came out to check out system clearly loves his job!
