What is one of the benefits of the correct layout of pipework and removal of air from a plumbing system?

• Increases water pressure

• Reduces noise in the system

• Increases the risk of corrosion

• Decreases water temperature

What does an air separator ensure in a plumbing system?

• Check valves

What might be the cause if radiators are not heating up and the hot water is only lukewarm?

• A broken thermostat

• A sluggish or poor performing pump

• A clogged filter

• A faulty heater

What is the purpose of isolation valves in a circulator pump system?

• To increase water pressure

• To allow easy maintenance

• To reduce noise

• To enhance water flow

Why is the positioning of the pump important in a plumbing system?

• To produce positive pressure and avoid air entering the system

• To increase water temperature

• To reduce water flow

• To decrease system pressure

What is the golden rule for the circulator in a plumbing system?

• It must always draw on the cold feed
