LG Hausys Interview Questions and Answers

The number of motor pumps used in plumbing lines varies depending on the specific plumbing system.

• The number of motor pumps used in plumbing lines depends on the size and complexity of the plumbing system.

• Some plumbing systems may require multiple motor pumps to ensure proper water pressure and flow.

• In general, residential plumbing systems may only require one motor pump, while larger commercial or industrial systems may require multiple pumps.

• The type of motor pump used also...read more

Valves are used in pipeline installation to control the flow of fluids or gases.

• Valves can be used to start, stop, or regulate the flow of fluids or gases in a pipeline.

• They can also be used to divert the flow of fluids or gases to different pipelines.

• Valves can be manual or automated, and can be made of various materials depending on the application.

• Examples of valves used in pipeline installation include gate valves, ball valves, and butterfly valves.

Pipe line slope can be calculated using the formula: slope = (rise/run) x 100

• Measure the distance between two points on the pipe line

• Measure the difference in height between the two points

• Divide the difference in height by the distance between the two points

• Multiply the result by 100 to get the slope percentage

• Example: If the distance between two points is 10 feet and the height difference is 2 feet, the slope would be (2/10) x 100 = 20%

Presor metar is a pressure meter used to measure the pressure of fluids or gases in pipes or tanks.

• Presor metar is commonly used in plumbing and HVAC systems.

• It can measure pressure in PSI, bar, or kPa.

• The process involves attaching the meter to the pipe or tank and reading the pressure on the gauge.

• It is important to use the correct type of presor metar for the specific application.

• Regular calibration and maintenance is necessary to ensure accurate readings.

Precautions must be taken before starting work to ensure safety and prevent accidents.

• Identify potential hazards and take necessary precautions

• Wear appropriate personal protective equipment (PPE)

• Ensure proper ventilation and lighting

• Follow safety protocols and procedures

• Have a first aid kit and emergency plan in place

• Examples: Lockout/tagout procedures, confined space entry procedures, fall protection measures
