Why the Free Water Test Comes First

The water treatment industry runs on package pricing and calendar-driven sales pitches. Puronics of Orange County runs on a different model: measure the water first, size the system to that reading, then quote the exact model. If the test does not warrant a system, we say so. Roughly one in five free water test visits ends with a recommendation not to purchase anything.

That is the honest reason the test is offered at no cost. We would rather spend an hour at a kitchen table telling a homeowner they do not need a softener than sell a system that does not fit the reading. Word travels in Orange County neighborhoods faster than any ad budget.

The Puronics Choice

Puronics has been building water treatment equipment since 1947 and now serves more than a million residential and commercial customers through 226 dealer locations. The SilverShield HYgene silver-ion technology at the heart of most Puronics systems use silver-ion technology adapted from NASA's Space Shuttle water purification research. That is what allows a Puronics system to run 15 to 20 years in service instead of the 5 to 8 year replacement cycle of most big-box softeners.

Gregg is an authorized Puronics dealer because the equipment holds up in the field and because the certifications (NSF/ANSI 44, NSF/ANSI 42, WQA Gold Seal) are the ones water professionals actually rely on. Every install is done under CA C-55 Contractor License #904801 with plumbing permits pulled per the city jurisdiction. The manufacturer warranty stays intact. Every install includes a two-year follow-up water test to confirm the system is still performing to spec.

From that office our team covers every Orange County city, from Yorba Linda in the north to San Clemente in the south, from Seal Beach on the coast to Rancho Santa Margarita inland.

"Professional installation, amazing results. Our plumber said the scale buildup in our old pipes was costing us hundreds in energy waste. The Puronics team was in and out in 3 hours. Highly recommend for anyone in Orange County."

"We compared Puronics to several local companies and it wasn't even close. The NASA technology, the certifications, the warranty, and they came to our house for a free test. No pressure at all. We've already referred two neighbors."
