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.
We prepare NYC DEP cross-connection plans and coordinate the filing, installation, testing, and closeout process for required backflow prevention systems.
We coordinate RPZ device selection, DEP plans, filing, licensed plumbing installation, certified testing, and final project closeout throughout NYC.
We prepare and coordinate DEP filings for DCV and DCDA backflow systems serving domestic water and fire-protection services throughout NYC.
We review building use, water services, and installed equipment to determine whether a documented NYC DEP backflow exemption path may be available.
We review NYC DEP backflow notices, determine the appropriate filing or exemption path, and coordinate the project through documented compliance.
We coordinate certified initial and annual testing for RPZ, DCV, and DCDA devices and organize the required records for DEP compliance.
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.
