During operating pressure test manometer should read about __ in Wc - Answer-11
This test is used to verify pressure at which the regulator locks up when no propane is
flowing - Answer-Lock up pressure test
During lock up pressure test reading must never exceed ___ in Wc - Answer-14
This test is used to determine if the propane system is leak free by dropping internal
pressure to 8 in Wc for 3 minutes - Answer-Timed pressure drop test
During a Pdi on the propane system technician should set delivery line pressure, verify
regulator lock up pressure, preform a ________ _________ _________, check
connections using a bubble solution - Answer-Times pressure drop test
Rv water distribution system needs what 2 things to function? - Answer-A source or
potable water and a means to provide pressure
4 Methods of obtaining pressure for water system - Answer-1. City water pressure
2. Demand pump
, 3. Manual pump system
4. Air pressurized
The water __________ system consists of piping, freshwater, storage tank, water
heater, water pump and faucets - Answer-Distribution
What is the purpose of the bypass valve on a water heater - Answer-Used during
winterization to keep antifreeze out of water heater
Accumulator: - Answer-Installed downstream of pump to assist with consistent water
pressure
Water regulator - Answer-Reduces water pressure (as high as 150psi) down to about
40-50psi
Water filters - Answer-Filter out impurities
The the water distribution system the High pressure check valve is located in 2 places
and does? - Answer-Located at the pump outlet to protect from city water pressure and
the water heater inlet to prevent back flow of water.
These gauges are used to test water systems for leaks - Answer-Pressure gauge
