Jim came on time to do the annual treatment of our water system and took the time to explain and train us on the 2 systems.

I’ve been a Garrelts customer for over 25 years. When I moved into my new home back then, my well water was almost undrinkable. Water softener did nothing to change the taste. I tried various filters to no avail. A neighbor told me about the Iron Curtain system he had from Garrelts. It has performed very well and I can count on Garrelts to provide excellent service. Jim is very knowledgeable and trustworthy. I highly recommend Garrelts

Jim was great to deal with, he came out the very next day to test and find a solution to our water problem. He explained what he was testing for and answered any question i had in detail, Great prices on equipment. I did the install myself, But he was more then willing to come out at no charge to start things up for me. He is the only guy i will use.
