I have two systems. In two different homes. One is nearly 20 years old. And both have worked flawlessly. Water was nasty and brown. Now it's crystal clear and tastes great. No regrets here. Thanks Mark for job well done!

We had a new water softner installed and our water is SO much better. Mark is very personable. He took the time to explain everything to me. We highly recommend him.
