MGA Plumbing is the Des Peres plumbing company to call for backflow testing. Our local plumbers are available 24/7, arrive on time and fix the problem right the first time. Real people answer the phone 24/7 and a plumber is dispatched fast.
Backflow preventers protect the public water supply from contamination and most utilities require annual testing by a certified tester. We test, certify, file the paperwork and repair or replace failed devices for homes, irrigation systems, fire sprinklers and commercial properties.
Call before your deadline — same-week scheduling is usually available.
Homes in Des Peres range from older houses with original galvanized and cast iron plumbing to new construction with PEX — and each needs a different approach to backflow testing.
