Backflow occurs when contaminated water flows backward into your home’s clean water supply. At BPM Heating, Cooling & Plumbing, we provide certified backflow prevention, installation, and annual testing to protect your potable water. We serve homeowners, businesses, and property managers across Maryland and Pennsylvania with fast, compliant service.
What Is Backflow and Why Does It Matter?
Backflow can happen when water pressure drops in your supply lines—from hydrant use, a burst main, or nearby construction. This pressure reversal can pull contaminated water from irrigation systems, boilers, fire suppression systems, or even garden hoses back into your drinking water. It’s dangerous, and in many areas, annual testing is required by law.
Backflow Prevention Devices We Service
We install, inspect, and test all types of backflow prevention assemblies, including:
- Double Check Valve Assemblies (DCVA)
- Reduced Pressure Zone Assemblies (RPZ)
- Pressure Vacuum Breakers (PVB)
- Atmospheric Vacuum Breakers (AVB)
- Anti-siphon valves for irrigation and hose bibbs
Our certified technicians ensure every device is properly installed, code-compliant, and operating as intended.
Annual Backflow Testing & Certification
Many municipalities require annual backflow testing to ensure compliance and protect public water. Our licensed backflow testers:
- Test each valve for proper pressure differential
- Inspect for leaks or mechanical failure
- Submit documentation to local water authorities
- Provide certification paperwork for your records
We offer convenient scheduling and reminder services to ensure you never miss a deadline.
Commercial & Multi-Family Compliance
Backflow protection is especially important for commercial and multi-unit residential properties. We work with:
- Office buildings
- Apartment complexes
- Restaurants and cafes
- Medical offices and dental clinics
- Gyms, schools, and religious facilities
We handle both new installations and annual testing for compliance with local ordinances.
