DEPARTMENT OF ENVIRONMENTAL PROTECTION

BUREAU OF WATER & SEWER OPERATIONS

REVISED SUPPLEMENT TO THE NEW YORK STATE DEPARTMENT OF HEALTH HANDBOOK FOR CROSS CONNECTION CONTROL

This supplement was last revised on (6/10)

Introductory Note:

This supplement will help you prepare backflow prevention plans for submittal. It is a guide only and should not be used as a substitute for experience in the planning and design of backflow prevention device installations. If you are not experienced with this type of work, we suggest that you consult with a professional.

To avoid the expense and delay necessitated by the removal and reinstallation of containment devices, we suggest that you have your plans approved by DEP before proceeding with installation.

For new facilities, aesthetic considerations and architectural design is an unacceptable reason for granting exemptions. The architectural design must accommodate the containment devices, not the other way around.

Please note that the filing Professional Engineer or Registered Architect is expected to review the potential for hazard posed by the occupancy of the premises.

Based upon this review, the filing Professional Engineer or Registered Architect should select an appropriate containment device in accordance with the latest revision of the DEP Cross Connection Control Risk Assessment.

WHAT LAW REQUIRES

Owners must install special plumbing devices, known as a backflow prevention device(s) on the water service pipes that supply their property. The device prevents water from flowing back into the City’s drinking water supply. Owners must obtain the approval of plans submitted to the Department of Environmental Protection (DEP) before installing the device and have the device tested by a state certified backflow-prevention device tester at least once a year. DEP’s Bureau of Water and Sewer Operations is charged with enforcing Part 5 Section 5-1.31 of the State Sanitary Code and Title 15, Chapter 20 of the Rules of the City of New York (RCNY).

HOW TO COMPLY

Step 1: A Professional Engineer (PE) or Registered Architect (RA) must prepare and submit two sets of plans and two applications originals (form GEN-236 New York City Version) for the installation of Backflow Prevention Device(s) to the Bureau of Water and Sewer Operations, Division of Permitting and Inspections for approval. All submissions must have original ink signatures and original ink or impression seals. Plans and applications must be corrected and resubmitted as necessary until acceptable.

Step 2: When the plans are approved, the Division of Permitting and Inspections issues a plan approval letter to the customer and returns one copy of the approved plans to the PE or RA of record.

Step 3: The device(s) must be:

Installed by a New York City Licensed Master Plumber in accordance with the approved plans (installations must also meet the Building Department’s and the Bureau of Customer Service’s requirements).

Tested by a State Certified Backflow Prevention Device Tester who is either a Licensed Master Plumber or employed by one. Inspected by a PE or RA and certified that they have found the installation to be in accordance with the approved plans.

Step 4: Finally, a completed “Report on Test and Maintenance of Backflow Prevention Device” (form GEN-215B), certifying the job, must be submitted to DEP within thirty days of installation of the device.

Step 5: Annual Inspection: At least once a year, the device must be inspected, maintained and tested, by a state certified tester. The results of the test must be reported to the department by filing Form GEN 215B with parts A & B properly completed.

Note: Be aware that some plumbers may provide “Turn Key” installation.

Page 2

Rev. 06/10

If you believe that your premise does not require a Backflow Prevention Device, you may have a Professional Engineer, Registered Architect, or Licensed Master Plumber submit a request for Exemption to the DEP Cross Connection Control Unit for consideration. If approved an exemption letter will be issued.

Steps for Installing Backflow Prevention Device

The following steps must be taken for the preparation, submission and approval of plans and the installation of backflow prevention devices for CONTAINMENT of facilities:

Step 1: A Professional Engineer (PE) or Registered Architect (RA) must prepare and submit two sets of plans and two applications originals (form GEN 236 New York City Version) for the installation of Backflow Prevention Device to the Bureau of Water and Sewer Operations, Division of Permitting and Connections for approval. All submissions must have original ink signatures and original ink or impression seals. Plans and applications must be corrected and resubmitted as necessary until acceptable.

Step 2: When the plans are approved, the Division of Permitting and Connections issues a plan approval letter to the customer and returns one copy of the approved plans to the PE or RA of record.

Step 3: Device(s) must be:

Installed by a New York City Licensed Master Plumber in accordance with the approved

 

plans (installations must also meet the Building Department’s and the Bureau of Customer

 

Service’s requirements)

Tested by a State certified Backflow Prevention Device Tester who is either a Licensed

 

Master Plumber or employed by one

Inspected by a PE or RA and certified that they have found the installation to be in

 

accordance with the approved plans.

Step 4:

Submit the “Report on Test Maintenance of Backflow Prevention Device” (Form GEN

 

215B), certifying the job to DEP within thirty days of device installation.

DEP will refer improper installations to the owner, PE or RA, or both. Improper installations must be corrected and re-certified (with Form GEN 215B) until acceptable. All installations are subject to inspection and verification.

Definitions for Commonly Used Cross-Connection Terms

AFF – Above finished floor.

Airgap – means the unobstructed vertical distance through the free atmosphere between the lowest opening from a pipe, RPZ discharge port, drain line or faucet supplying water to a tank, plumbing fixture floor drain, or any other device. This approved airgap shall be at least double the diameter of the supply pipe, measured vertically, above the overflow of the vessel; and in no case less than one inch. For RPZ’s, an airgap may be based on twice the effective diameter of the relief port.

Airgap Fitting – is a manufactured device which fits on the RPZ’s discharge port and is designed to serve as an airgap. When a manufacturer’s airgap fitting is used and a drain pipe carries the relief port discharge to a drain or sewer, an additional free atmosphere airgap is needed between the end of the relief port discharge pipe and the drain or sewer opening.

Acceptable Backflow Prevention Device – is an acceptable airgap, approved reduced pressure zone device (RPZ), or approved double check valve (DCV, DCVA). Approved devices are those that are listed by The New York State Department of Health.

Aesthetically Objectionable – refers to substances (e.g. stagnant water, hot water) which if introduced into the water supply system, could be a nuisance to other water customers but would not adversely affect human health.

Approved Device – RPZ or DCV, which has been listed by The New York State Department of Health as an acceptable backflow prevention device. Others are not acceptable.

Backflow – The reversal of the normal flow of water caused by either backpressure or backsiphonage.

Containment – the means which isolate customers’ entire facility from the public water system so as to provide the protection necessary to prevent contamination of the public water supply in the event of contamination within the customers’ facilities.

DCV – double check valve, device with two single, independently acting check valves, including tightly closing shutoff valves located at each end of the assembly and suitable connections for testing the watertightness of each check valve, and listed by the New York State Department of Health.

Hazardous Facility – is one in which substances may be present which if introduced into the public water system would or may endanger or have an adverse effect on the health of other water customers.

Horizontal Alignment - the distance from the middle of the device to the nearest front or back wall, and the distance to the nearest side wall. (In some cases, reference can be made to a column, curb, or some fixed conspicuous object.

MOCV – Meter Outlet Control Valve, the line valve that is used in conjunction with the test tee to test the meter. This valve shall be located on the house side of the test tee in order to prevent water flow to and from the facility during meter testing.

RPZ – Reduced Pressure Zone Backflow Prevention Device. A device containing two independently acting check valves on both sides of an automatically operated pressure differential relief valve, all located between two resilient seated shutoff valves. Acceptable devices must be listed by the New York State Department of Health.

Side Clearance – is the clear horizontal distance between the side of the device to the nearest side wall (i.e. wall parallel to the water flow).

Test Tee – a tee used for testing the meter.

Vertical Position – distance above the finished floor AND

INSTRUCTION FOR COMPLETION OF

“Report on Test and Maintenance of Backflow Prevention Device”

(FORM GEN-215B)

Use a separate form for each device

Initial Test and Certification: complete all 4 parts

Annual Re-Certification: complete parts A and B only

Part A: To be completed in ALL cases:

Part B: Certified Backflow Prevention Device Tester must fill out this portion in All cases:

Be sure to answer Question 1. If the answer is “YES”, explain in the space provided. A connection for a properly installed and certified parallel device should not be construed as a connection. Hose cocks and spigots must be considered as connections. Tees must be considered as outlets unless they have been PERMANENTLY plugged or sealed. (Tees may be plugged by welding on blank flanges or by screwing in a plug and cutting the plug off flush with the face of the tee). Plugged tees will only be acceptable for old work. Tees on the street side of the backflow prevention device will not be allowed on new jobs. Risers, feeds to boilers and the like must be construed as connections.

Indicate INITIAL TEST or Re-CERTIFICATION

Clearly print, type or rubber stamp: Name, Certified Tester # and Certified Tester Expiration Date

Include the line pressure (taken at number 1 test cock with shutoff valve number 1 closed)

Include the pressure drop across the first check valve (the pressure differential between the second and the third test cocks).

Completion time of test refers to the time of day (e.g. 8:00 am).

If there is no water meter, indicate this on the form.

Part C: Complete For INITIAL TEST Only!

The Professional Engineer or Registered Architect (PE/RA) must complete Part C.

Be sure to fill in the “Water Supplier Approval #”

Indicate whether you are the designer of record or not

Indicate minor changes if there are any. Use back or additional pages as required.

Indicate “See Back” or “See Additional Pages” as appropriate. If a device different than the approved device is used, the PE or RA must specify that the submission is acceptable and will not cause any adverse hydraulic effects

If the installation changes meet DEP requirements while deviating from the approved plans, the job may be resubmitted for re-approval or an As-built Record Drawing may be submitted

When the installation deviates from the approved plans and required minimums are not satisfied, the job should NOT be certified.

Part D: The Professional Licensed Master Plumber must complete Part D

Be sure to fill in the Building Department Number (ARA #, ALT#, NB#, etc). Use of sticker is preferred.

Indicate if you are the Licensed Master Plumber of record or not

Indicate Licensed Master Plumber’s Name. Licensed Master Plumber’s License #. Licensed Master Plumber’s Telephone Number. Use Original Ink Signature Raised Impression Seal of Licensed Master Plumber & Date

The Tester, the PE or RA & the Licensed Master Plumber should all sign the same form for each particular device.

For each of the completed forms, USE ORIGINAL INK SIGNATURES & ORIGINAL INK OR RAISED IMPRESSION SEALS.
