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.
Because we dispatch from the Mid-Missouri area, a MGA Plumbing plumber can usually reach any address in St. James fast — including Columbia and Jefferson City. For backflow testing emergencies, that speed is the difference between a simple repair and major water damage.
