Do I have a backflow device?

These devices are installed on all new and renovated buildings, both residential and commercial. They are also installed on any property with an irrigation system, fire suppressant system, or larger boiler. Backflow devices are also required to be installed on all new or renovated commercial buildings.

Why do I need my backflow device tested?

Contaminants or stagnant water can sometimes infiltrate these systems which can lead to bacteria growth. If a problem arises in your water or septic system that may cause the pressure to drop like a water main break, hydrant flushing, or water leak, the bacteria-laden water can sometimes make its way into your drinking water. The backflow testing device prevents this from happening.

What are the backflow device laws in Maryland?

In Maryland, it’s a law that new backflow devices need to be inspected by a certified professional.

Prime Reviews

“Nothing but good words to say about the team at Prime Plumbing. I had a severe leak in my kitchen. Previous contractor did not install my new sink and garbage disposal correctly. I called Prime, they sent Ryan (just excellent) and he clearly explained what the problem was and provided several solutions. I agreed to the terms and Ryan did a bang up job with the repair and clean up. I will definitely call Prime for my plumbing needs.”

“Prime Plumbing LLC could not have been more accommodating for us. Tony was our service tech and he was very knowledgeable and professional. The owners of Prime Plumbing went far beyond to help us during a frustrating time. This company is excellent and I would highly recommend them. My sincere appreciation to their entire team.”

“The service we received was beyond our highest expectations. We made a last-minute call expecting to have a technician arrive the next day, but we’re lucky enough to have a technician in the area. He was appropriately covered for COVID-19, extremely personable, professional and very knowledgeable about our make of jacuzzi tub. We received a prompt diagnosis and on the spot repair with minimal interruption of our household.”
