At Victory First Enterprises. LLC we work hard to bring each customer the best possible service and quality available. We look forward to working with you on your next water treatment system project. We welcome your questions and thank you for your interest.

"Love the Puronics system. We’ve been a loyal customer since July 2015. Never had a issue at all and have recommended to everyone that’s ever asked HOWEVER my only disappointment is we were told that they would remove and instal one time for free if we moved. We are getting ready to have our floor coated and although we aren’t moving we called to ask if they could unhook it for a week and hook it back up. (Same as a move in my opinion) and they said, if it’s not in your contract then it’s $500+ to do it. What a bummer!! So no matter what the sales person tells you, MAKE SURE ITS IN THE CONTRACT because verbal agreements don’t get honored."
