Annual backflow preventer testing, repair and certification for homes and businesses. Available 24/7 in every NH city and town.
(888) 480-9811Backflow preventers keep contaminated water from flowing back into the public supply, and most towns require annual testing. MJA Plumbing and Heating tests, repairs and certifies backflow assemblies for homes, irrigation systems and commercial properties and files the paperwork.
A real person picks up day or night, and an emergency plumber is dispatched immediately.
You get the price in writing before we start. No surprises on the invoice.
Most repairs finish on the first visit because the parts are already on the truck.
Our plumbers live and work in the communities we serve and know the local water and winters.
Shoe covers, drop cloths and a tidy job site every time.
If a repair we made fails, we come back and make it right.
We can put your property on an annual reminder so you never miss the town deadline.
