Maintenance Indicators

What should be checked if there is a poor flow rate according to the maintenance indicators?

• Temperature settings on thermostat

• Limescale blockages

• Filters cleaned

• All of the above.

Which of the following is a possible cause of poor flow rate in pipes?

• Valves are fully operational

• Limescale blockages

• Proper lubrication of parts

• Correct pipe size

To ensure the temperature settings on a thermostat are correct, what should be checked?

• The thermostat's power source

• The thermostat's location

• The thermostat's calibration

• The thermostat's display brightness

It is important to have filters cleaned and pipework inspected in showers because:

• it ensures proper water flow and hygiene.

• it increases the water temperature.

• it changes the color of the water.

• it reduces the water pressure.

What should be ensured about valves in shower maintenance?

• Valves should be regularly cleaned

• Valves should be replaced every year

• Valves should be checked for leaks

• Valves should be painted

What should be done if an isolation valve is old or hasn’t been closed for a period of time and may not close fully?

• Replace the valve

• Ignore the issue

• Force the valve closed

• Lubricate the valve

What is the first step in maintaining a valve that is passing water?

• Inspect the valve for visible damage

• Replace the valve immediately

• Tighten the valve packing

• Lubricate the valve stem

What happens if the thermostat fails in the open position?

• A) The customer will have no hot water.

• B) The temperature will continue to rise.

• C) The water will become too cold.

• D) The system will shut down.

What should you check first if there is no hot water due to a failure of the heat source?

• The thermostat settings

• The water heater power supply

• The water pipes for leaks

• The hot water tap

What happens if the coil fails in a cylinder?

• The pressure from the CWSC is less than the pressure from the F&E cistern.

• Water is forced into the primary system.

• The warning pipe on the F&E does not discharge.

• Hot water remains clear.
