Family Owned, Customer Focused

Water Treatment Technologies has been a success in large part because of our efforts to bring the small town attitude of personalized service, hard work, and ethical business practices to the big city.

For over 30 years, that’s been our commitment to both our commercial and residential customers as well as to our employees. We treat our employees like family!

We pride ourselves at problem solving water treatment equipment issues when you need them solved, not days or weeks later. We want to ensure your system is properly maintained so you don’t need to take advantage of our 24×7 emergency water treatment services.

Water Treatment Technologies, Inc. started in January of 1992, by Robin and Andi Pettyjohn.  They concentrated on providing high quality, honest water treatment services. They then expanded to water treatment equipment sales and rentals as their customer base increased

Paul Kaplan – Certified Water Treatment Specialist

Over the years, the business grew.  In 1998 they brought on Paul Kaplan as a service technician.  Paul jumped into educating himself about water treatment and became certified through the Water Quality Association as a Certified Water Specialist and Installer.

Paul then became the Service Manager overseeing all Commercial and Residential accounts as well as all technicians.  We are  fortunate to have service technicians and an office staff that have been with us for close to 15 years.

Paul and his team have seen it all at in both residential and commercial environments so they can answer all of your water system questions.

In 2023, after 27 years with the business, Paul Kaplan and his wife, Kerri, became minority partners in the business and will be full owners in 2026.  They are working together with the Pettyjohns to continue to build Water Treatment Technologies and expand on what they have built over the last 30+ years.

We sell, rent, and service water treatment solutions, including water softeners and reverse osmosis systems, in the Greater Phoenix area.

If you have questions or aren’t sure if we service your area, just call us at 602-275-8280 and we’ll get you taken care of.
