Why Connecticut homeowners choose Drain Wizard for backflow prevention
Backflow Prevention in an older Connecticut home rarely fits a one-size-fits-all repair. Greater New Haven's housing stock spans century-old cast iron and galvanized systems, mid-century copper and clay laterals, 1970s Orangeburg, and modern PEX & PVC — each behaves differently and each has a right way to service it. Drain Wizard is a family-owned, Connecticut P1-licensed plumbing contractor based in Hamden, and backflow prevention is core to what our experienced plumbing professionals do every week across Hamden, North Haven, Wallingford, Cheshire, Branford, Guilford, Madison, Milford, Meriden, New Haven and the rest of the region.
Every backflow prevention call starts with a real diagnosis — not a guess — and a detailed written estimate you approve before any work begins. We show up when we say we will, protect your home with drop cloths and shoe covers, and stand behind the workmanship with the Drain Wizard Guarantee. If a permit or inspection is required, we pull it and see it through.
