BAT Backflow Assembly Tester Safety & Regulatory Compliance 3

Question 1

An RPZ assembly's relief valve is continuously discharging during normal operation. What does this MOST likely indicate?

Accepted Answer

Downstream pressure is higher than upstream pressure

Answer

Continuous relief valve discharge during normal operation typically means backpressure conditions exist, with downstream pressure exceeding upstream.

Question 2

Which ASSE standard covers the performance requirements for pressure vacuum breaker assemblies (PVBAs)?

Accepted Answer

ASSE 1013

Answer

ASSE 1013 establishes the performance requirements for pressure vacuum breaker assemblies used in cross-connection control.

Question 3

A tester notices the test cocks on an assembly are corroded and will not open. What is the correct course of action?

Accepted Answer

Document the condition and report the assembly as untestable

Answer

If test cocks cannot be operated safely, the assembly should be documented as untestable and reported to the owner for repair or replacement.

Question 4

Under USC cross-connection control manual guidelines, what is the minimum acceptable air gap ratio for a potable water supply to a tank?

Accepted Answer

2x the effective pipe diameter, minimum 1 inch

Answer

The USC manual specifies an air gap of at least 2 times the effective pipe diameter with a minimum of 1 inch.

Question 5

A fire sprinkler system connection to the potable water supply requires which level of backflow protection per NFPA 13?

Accepted Answer

DCVA for non-chemical systems, RPZ for antifreeze systems

Answer

NFPA 13 requires a DCVA for non-chemical fire systems and an RPZ for systems containing antifreeze or other additives.
