In Fredericksburg, we replaced an out-of-date OxyTech iron and sulfur unit with a brand new Pristine Water air injection iron and sulfur unit. Some of the older pieces of equipment were kept in, as we only replace what we need to. We believe that if it ain’t broke, don’t fix it! We thank you for choosing Pristine Water! To schedule a free water test or if you have a concern about your home’s water quality, call us at (571) 334-8283!
