From downtown Bismarck to every corner of Bismarck, MGA Plumbing provides expert backflow testing with upfront quotes and a satisfaction guarantee. Book online or call (888) 480-9811.
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 Bismarck 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.
