Bobby was a great help today. He was very professional and knowledgeable. He walked me through everything. He did get my water running again and gave me recommendations to replace my old system. On Wednesday 1-28-26 Bobby and Sam S came to my home to install the new water system. They were very prompt and professional. They worked all day and performed miracles in my basement. They both explained everything they were going to do and when completed explained in detail everything I would need to know. They are both very knowledgeable, communication is excellent and making sure you are happy with their work. I would definitely recommend them again. If I have any issues they would be my first call.

Sam was fantastic! On time, knowledgeable, and completely professional. Ours was an unusually difficult installation due to the location of our water source. Sam evaluated the situation and quickly devised a plan that worked. I can't say enough good things about our experience, and I would highly recommend them.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We offer transparent, upfront pricing for all of our services. New system installations come with a free in-home consultation that includes a in-house water test. Our service fee is $135 for repair and service work. Material charges are presented in-home and all charges are approved by the homeowner before work is performed. Payment is due upon completion of the job.
What is your typical process for working with a new customer?
For new customers looking to have a water filtration system installed, we start with a free in-home or virtual consultation that includes a free 4-point water test (additional testing can be purchased if desired). Based on the results of the test, the customer's needs, and the specific design of the plumbing in the home, we provide options for custom-designed water treatment and filtration systems. Once approved, we schedule our in-house installation team to complete the installation in accordance with local plumbing codes. All of our work comes with a 100% satisfaction guarantee.
What education and/or training do you have that relates to your work?
1. We are members of the Water Quality Association (WQA) with over 25 years of industry experience.
