BAT Code Compliance & Standards 3

Question 1

According to USC FCCCHR guidelines, what is the maximum allowable pressure loss across a properly functioning reduced pressure principle assembly under normal flow conditions?

Accepted Answer

No specified maximum

Answer

The USC FCCCHR does not specify a maximum pressure loss for normal flow; instead, RP assemblies are evaluated by their differential pressure readings during testing.

Question 2

Which ASSE standard applies to double check backflow prevention assemblies used in plumbing systems?

Accepted Answer

ASSE 1012

Answer

ASSE 1015 covers double check backflow prevention assemblies, while ASSE 1013 covers reduced pressure principle assemblies.

Question 3

A pressure vacuum breaker (PVB) installed 6 inches below the highest downstream outlet is in violation of code. What is the minimum required elevation above the highest outlet?

Accepted Answer

12 inches

Answer

Code requires a PVB to be installed at least 12 inches above the highest downstream outlet or point of use to prevent backsiphonage.

Question 4

Which of the following installations would violate USC Model Water Code requirements for a double check detector assembly (DCDA)?

Accepted Answer

Boiler feed line using corrosion inhibitors

Answer

A boiler feed line using corrosion inhibitors is a high-hazard application requiring an RP detector assembly, not a double check detector assembly.

Question 5

Under AWWA M14 (Backflow Prevention and Cross-Connection Control), what is the recommended minimum frequency for testing high-hazard backflow prevention assemblies?

Accepted Answer

Every 6 months

Answer

AWWA M14 recommends semi-annual testing for high-hazard assemblies to ensure continued protection of the potable water supply.
