Circulator Pump Quiz

What is used to maintain a watertight seal in the circulator's pump flanges?

• Rubber or fibre washers

• Metal clamps

• Plastic seals

• Glue

What allows the pump to be removed without draining the system?

• Full bore valves

• Pressure release valves

• Overflow pipes

• Drainage taps

What is the importance of the correct positioning of the circulator in a system?

• To enhance water flow

• To avoid corrosion by aeration

• To increase system pressure

• To reduce noise levels

What can happen if air is drawn into the system water?

• The system will become more efficient

• Corrosion will take place

• The water will heat up faster

• The system will shut down

What is the purpose of adding an inhibitor to the system water?

• To increase water temperature

• To reduce corrosion and scale build-up

• To enhance water flow

• To decrease water pressure

Where is the neutral point of the system located?

• At the top of the hot feed

• At the base of the cold feed

• In the middle of the system

• At the end of the vent

What must the pump always draw on?

• Hot feed

• Neutral point

• Cold feed

• Vent

What happens to the system water if the circulator is correctly followed?

• It will be circulated under a positive pressure.

• It will be circulated under a negative pressure.

• It will stop circulating.

• It will overflow.

What could occur if the circulator is not correctly followed?

• The system water could be circulated under a negative pressure.

• The system water will remain stable.

• The system water will evaporate.

• The system water will freeze.
