This document is a detailed trip report for a backflow prevention assembly inspection conducted at the U.S. Embassy in Paris, France from April 15-19, 2024. The inspection covered nine locations including the Embassy compound, Boulogne, Neuilly Residence, CMR, OECD, Weber, Leopold II, GMC, and Deschanel, revealing multiple critical backflow prevention deficiencies.

Key findings include the need to install 24 Reduced Pressure Assemblies (RP), replace eleven existing RPs that failed backflow tests, and address multiple plumbing safety issues such as water softeners directly connected to sewer lines, coffee machines lacking proper valves, ice maker drains improperly connected, and dishwashers without required backflow prevention. The report provides specific recommendations for each location, including precise model numbers for replacement backflow prevention assemblies from manufacturers like Watts and Zurn Wilkins, along with detailed product links, ordering codes, and repair kit specifications. The inspection was conducted using a Mid-West Instrument 835 Back-flow Test Kit and involved embassy contacts including the Senior Facility Manager, Deputy Facility Manager, Data Analyst, and Plumber.

TRIP REPORT - BACKFLOW PREVENTION ASSEMBLY INSPECTION AND

MAINTENANCE

FROM: THE HAGUE US EMBASSY-MOROS EVANGELOS

SUBJECT: Trip report – France, Paris US Embassy, April 15-19-2024

OVERVIEW AND PURPOSE OF THE TRIP

According to the International Plumbing Code (IPC), each backflow-prevention assembly is required to be tested at least annually.

EXECUTIVE SUMMARY

• The inspection covered nine locations: the Embassy compound, Boulogne, Neuilly Residence, CMR, OECD, Weber, Leopold II, GMC, and Deschanel.

• It is recommended to install Reduced Pressure Assembly (RP) in 24 locations.

• Eleven Reduced Pressure Assembly (RP) were discovered, but all failed the backflow test.

• Five water softeners are connected directly to the sewer line. Air gaps must be installed.

• One coffee machine is not equipped with a Dual Check valve, and the drain is directly connected to the sewer line. Therefore, it is necessary to install a Dual Check Valve and air gap.

• One coffee machine is equipped with a Dual Check valve and air gap, which means it is compliant.

• Six ice maker drains are directly connected to the sewer line.

Therefore, an air gap must be installed.

• Six dishwashers are using a chemical feed system and do not have a Reduced Pressure Assembly (RP) installed. Additionally, their drain is directly connected to the sewer line, which poses a safety concern.

Therefore, it is necessary to install a Reduced Pressure Assembly (RP) and air gap to ensure the safety of the system.

• The car wash area is not equipped with a Reduced Pressure Assembly (RP), and the drain is directly connected to the sewer line.

Therefore, it is necessary to install a Reduced Pressure Assembly (RP) and air gap.

• Three disinfection cleaning units have dual check valves. However, to ensure the safety of the drinking water supply, a Reduced Pressure Assembly (RP) and air gap for high-hazard chemicals must be

2 | P a g e installed between the disinfection cleaning unit and the main water supply.

• It is recommended to install a hose bibb vacuum breaker on every hose bibb to prevent the backflow of contaminated water into the main water supply.

At the Embassy, several techniques are available for measuring the size of water pipes, as different people use different methods. The Embassy generally measures nominal pipe size

(NPS) in inches, while European pipe sizes are designated in millimeters as diameter nominal (DN) under the ISO standard. The term nominal bore (NB) is also sometimes used interchangeably. This report will use NPS (inches) to refer to pipe sizes. The Embassy is strongly advised to verify all pipe diameters before ordering the backflow preventer assembly or devices.

General Installation Details

• The installation guidelines stated in this report must comply with the U.S. National Plumbing Code.

• All Reduced Pressure Assemblies (RP) shall be installed between 12 and 36 inches above the floor or finished grade, with enough clearance for easy testing and maintenance. A fixed platform, portable scaffold, or lift that meets OSHA standards must be provided if installed at a greater height.

• Account for required sided clearance from the wall of Double Check and Reduced

Pressure Assemblies (1/2"-3") are 24" from side test cocks, 12" from top mounted test cocks, with 24" access from one side. For sizes 4" and above, double these requirements.

Drainage

• Drainage for backflow prevention assemblies shall be provided for all installations of DCV or RP to accommodate discharge during testing or draining of the unit and for RP relief valve discharges, as follows:

• Discharge from relief valves must be readily detectable to maintenance personnel either visually or using water level alarms, flow indicator lights, etc.

• All drainage from Reduced Pressure Assembly (RP) must be by gravity drains.

• An air gap between the RP relief valve opening and discharge piping must be maintained. The air gap must be at least twice the dimension of the relief valve's effective opening but in no case less than 1 inch.

• The manufacturer's air gap fittings may be utilized, provided they maintain a proper air gap and do not enclose or cover the relief valve. These fittings are only sized to handle intermittent and low-flow discharges. Additional drainage capacity may be required to accommodate a catastrophic relief valve failure.
