◍ Waterborne Disease.
Answer: Any disease that is capable of being transmitted through water.
◍ what is the maximum pressure drop allowed through a double check valve
assembly.
Answer: 10 psi
◍ Before repairing a backflow Prevention assembly you should.
Answer: all of the above
◍ Pressure Vacuum Breaker (PVB).
Answer: A backflow prevention assembly consisting of one independently
operating spring-loaded check valve (loaded closed) and an independently
operating spring loaded air inlet valve (loaded open) located on the
discharge side of the check valve(s), with properly located test *****, and
tightly closing shutoff valves on each side of the check valve. A PVB is
testable and protects against backsiphonage only, not backpressure.
◍ Performance Evaluation.
Answer: An evaluation of an approved backflow prevention assembly using
the latest approved testing procedures in determining the status of the
assembly.
◍ relief valve funnels on RP devices are specifically designed to carry the
, maximum possible flow from any discharge situation.
Answer: false
◍ The supplier of water shall retain the six most recent reports of test
conducted on pressure vacuum breakers.
Answer: false
◍ Flood-Level Rim.
Answer: The top edge of a receptor from which water overflows.
◍ deterioration of rubber parts normally occurs before metal and corrosive
water supplies.
Answer: true
◍ Liability.
Answer: Legally responsible for or being obligated by law for the protection
of the potable water supply.
◍ The Indiana State board of health test evaluates and approves backflow
prevention assemblies.
Answer: false
◍ A booster pump shall be set to stop when the suction pressure drop below
____ in a domestic system, and ____ in a fire suppression system.
Answer: 20psi, 10psi
◍ Degree of Hazard.
Answer: The danger posed by a particular substance or set of circumstances.
◍ Plumbing.
Answer: Any arrangement of pipes, fittings, fixtures or other devices for the
purpose of moving liquids from one point to another, generally within a
single structure.
◍ double check valve assemblies shall be tested at intervals not exceeding.
Answer: 1 year
◍ which year did the federal "state drinking water act" become law.
Answer: 1974
, ◍ Distribution System.
Answer: A system of conduits (pipes, laterals, fixtures) by which a potable
water supply is distributed to consumers.
◍ a customer granted an assumption show report to the commissioner and to
the supplier of water. any proposed changing process, plumbing or in
materials used or stored at the exempted facility.
Answer: true
◍ Venturi Effect.
Answer: A hydraulic principle that states that as the flow path is restricted, a
fluid will exhibit a greater velocity and a reduced system pressure through
the restriction.
◍ If the relief vent of a RP starts to drip after turning off shut off valve #2, this
indicates:.
Answer: Check Valve #1 leaks
◍ When testing a pressure vacuum breaker the air inlet must open before the
gauge falls to.
Answer: 1 psi
◍ Negative Pressure.
Answer: Pressure that is less than atmospheric; negative pressure in a pipe
distribution system can induce a partial vacuum that can siphon nonpotable
liquids into the potable water.
◍ a water supplier can terminate service to a user who fails to protect the
distribution system with a backflow preventer.
Answer: true
◍ It is permissible to have a shutoff valve downstream from an atmospheric
vacuum breaker.
Answer: false
◍ weight of one gallon of water.
Answer: 8.34
