NYC DEP Backflow Device Services
DEP cross-connection plans, RPZ and double check valve filings, installation coordination, testing, and GEN-215B sign-off support for NYC properties.
Most backflow problems are not really mechanical. They are filing problems, agency problems, and documentation problems. We handle all of it.
Plans, drawings, and documentation prepared for NYC DEP review and approval, sealed by a Professional Engineer or Registered Architect.
Reduced Pressure Zone device design, filing, drainage coordination, and inspection support for higher-hazard applications.
DCV and DCDA filings for lower-hazard and fire-service conditions, with full DEP approval support.
Initial and annual testing by certified personnel, test report preparation, and DEP submission.
Inspection coordination, RA/PE signature and seal, and final filing package for DEP and DOB closeout.
Backflow violation response, missing test correction, and documentation recovery for owners with active DEP notices.
Most backflow problems get worse when handled in pieces. Separate engineer, separate plumber, separate tester, separate filer. We run the full process under one team so the work moves forward instead of sideways.
DEP requires backflow plans to be filed by a Professional Engineer. Our filings are sealed and submitted by qualified professionals.
Annual backflow testing by certified personnel, with reports prepared and submitted in the format DEP requires.
GEN-215B sign-offs, RA/PE seals, and complete filing packages organized for closeout, audit, and future diligence.
