Nayi went above and beyond to help me figure out my RO System issue. Highly recommend their products and services. Absolutely amazing ❤️ RAUL HORACIO RODRIGUEZ 21:59 06 Oct 23 Ms. Claudia Imamovik does an extraordinary job of providing advice and careful attention. Your information is Clear, complete and detailed. Likewise, the speed with which he prepares orders allows me to optimize my work times and I am sure that when I ask him a question or make a purchase, it will be the best in terms of price and quality. Cesarin Martínez 03:18 06 Oct 23 Luis Palacios 22:02 05 Oct 23 Nayi does a fantastic job! Great customer service and Products. Our Sales Rep Terrell is always available to our needs from ordering to be punctual with our orders. Cameron Biberdorf 20:51 05 Oct 23 I called Waterworld USA after being referred to them by a specific valve manufacturer fully knowing that I could not purchase from directly as I have been putting in the time to research not only a quality Water Softening/Treatment system. The rep at Waterworld was exactly the kind of person you would want to work with! He explained things in a very real world and general way and cut through the fluff if you will. Made things much easier to understand and would encourage anyone to reach out to them with questions so that your plumber can interact with them for whateve you need because they do not sell to the consumer and that is ok because I was looking for real life answers to questions I had! Cam B Brandon Cyphert 16:45 05 Oct 23 It has been my privilege to engage in a professional relationship with this exceptional company for the past five years. The quality of their products, coupled with the expertise and approachability of Claudia, Jeronamo, Tyrell, and Less, has consistently impressed me. Their commitment to professionalism is unparalleled, and I wholeheartedly endorse this company. Daniel Garcia 16:06 05 Oct 23 Terrell is always good at assisting us and answering any questions we may have. Always a pleasure doing business with him. C J McDaniel 20:08 10 Mar 22 I am just a regular consumer who decided to reach out to Waterworld to try to gain some insight to how their system works compared to what I have already....and to try to determine if I need to replace my system. I was not expecting the kind of professional and courteous response I received. Matthew took a tremendous amount of time answering all my tedious questions and provided a lot of additional insight that will assist me in deciding what to do about my existing system.And the amazing part was he was not making this a sales pitch on their system, but trying to help me address my problems. IF I have to change or add something to my system, I will definitely support Waterworld by buying their product over another because of the time and energy expended by the company to help me better understand water filtration systems. anthony hoang 23:47 10 Feb 22 I called and asked for technical informations about my new Hydroblue Water Softener with the company agent. The online tech responded to my questions via text message very fast and in details. The company is willing to help me no matter who was the tech that installed my Hydroblue water softener. I am very satisfied with the company’s online information service. water girl 16:58 12 Jan 22 Great people michael Yourgules 16:04 28 Sep 21 Great customer service! Awesome employees.
