New York City properties with certain uses, equipment, or water-service conditions may be required to install an approved backflow prevention device.
BDS.nyc prepares and coordinates DEP cross-connection control plans for domestic and fire-protection water services. We review the property conditions, determine the appropriate filing path, prepare the required drawings, and coordinate the project through DEP review, licensed installation, certified testing, and closeout.
Our goal is to keep the architect or engineer, Licensed Master Plumber, tester, owner, and DEP working from one coordinated scope.
Cross-connection plans document the building’s water-service arrangement and the proposed backflow prevention device.
The drawings typically identify the incoming water service, meter configuration, proposed device type, valves, bypasses, drainage, clearances, and other required system components.
Plans must reflect actual field conditions and be prepared and sealed by an appropriately licensed professional where required.
Our service may include:
An incomplete or inaccurate plan can result in DEP objections, incorrect installation, added plumbing costs, or the need to modify completed work.
Early coordination helps establish the correct device, location, service configuration, and filing requirements before installation begins.
BDS.nyc manages the cross-connection process as a coordinated compliance project rather than treating the drawings, installation, testing, and sign-off as disconnected services.
We help keep the approved plans aligned with field conditions, plumbing work, testing requirements, and DEP documentation. This reduces vendor confusion, filing discrepancies, and delays caused by nobody taking ownership of the entire process.
