Commercial Plumbing Services
Plumbing issues affect more than pipes. They disrupt occupants, daily operations, and the overall reliability of a building. Metro Group delivers commercial plumbing services focused on dependable performance, clear communication, and long‑term results.
Backflow Prevention Services
The NYC Department of Environmental Protection (DEP) requires most commercial/industrial buildings and large residential properties to perform annual backflow prevention testing. Testing must be completed by a licensed Master Plumber certified in backflow prevention, with results submitted to the DEP to avoid violations and fines.
Backflow prevention services help protect water quality, maintain compliance, and ensure system safety. Regular testing, maintenance, and proper documentation reduce inspection issues and streamline regulatory requirements.
Backflow Testing, Repairs, and Installations
Required backflow testing and inspections are performed to support annual backflow prevention device inspection requirements, including DEP compliance where applicable. Repairs are completed when deficiencies are identified, and new backflow prevention devices are installed where required by system design or regulation.
Clear documentation is provided following inspections and testing to support filings, audits, recordkeeping, and ongoing compliance obligations.
