Good installers share a few habits; bad ones share a few tells. Here's how to filter. ## 1\. Confirm Arizona Licensing Every legitimate AZ plumbing contractor has an ROC number you can look up at azroc.gov. No ROC on the quote, no deal. Dominick Plumbing is ROC #350819. ## 2\. Ask How They Size the System A real installer asks: how many people, your average daily use (last bill), the hardness reading at the tap (they should test), and whether you have a pool, recirculation pump, or RO. Quotes without those answers were sized by margin. ## 3\. Compare Equipment Apples-to-Apples A 48k metered two-tank isn't the same as a 48k timer-based single tank. Look for metered (demand-initiated) regeneration, NSF-certified valve internals, and a 10-year+ resin tank warranty. ## 4\. Read the Warranty, Not the Brochure Manufacturer warranties cover equipment. **Labor warranties** cover the install — that's where most "lifetime" claims fall apart. Minimum: 1 year labor, written on the invoice, installer named. ## 5\. Red Flags - "Free" softener with multi-year financing - Door-to-door tests with high-pressure closes - PO box only, no physical address - No reviews older than six months ## Second Opinions Welcome Dominick Plumbing will review another company's quote alongside ours, no obligation.
