We purchase our water softener and filtration equipment through Duff and install it for our customers homes. The products have been great and their team is always easy to work with. We’ve had a great experience working with Duff and appreciate the partnership!

Copperhead Plumbing has used duff for many years. I recently had to order some equipment I was not to familiar with. Floyd was a great help all the way from ordering the proper equipment to me calling him to help me through the control set up. Everything worked flawlessly. I look foward to working with them on future jobs.
