• 1 bar

• 1.5 bar

• 2 bar

Are there electric shower models available for cistern-fed cold water supplies?

• Yes, but only for high-pressure systems

• No, they are only for mains water supply

• Yes, some models are available

• No, electric showers do not support cistern-fed systems

What do shower mixing valves fed from a storage cistern require to maintain the correct mixing ratio of hot and cold water?

• Different pressures on the hot and cold supplies

• Equal pressures on both the hot and cold supplies

• Higher pressure on the cold supply only

• Higher pressure on the hot supply only

Which type of valve is considered the safest for maintaining a constant temperature irrespective of the temperature of the incoming hot and cold supplies?

• Manual valve

• Thermostatic valve

• Ordinary mixing valve

• Pressure-balanced valve

Are ordinary mixing valves used with cistern-fed supplies thermostatically controlled?

• Yes, they are always thermostatically controlled.

• No, ordinary mixing valves are not thermostatically controlled.

• Yes, but only with additional equipment.

• It depends on the brand of the valve.

Where should the connection of cold water feed to the cylinder be made in relation to the cold feed for the shower?

• At the same level

• Lower than the cold for the shower

• Higher than the cold for the shower

• Outside the building

At what angle should the connection to the cylinder be made?

• 90°

• 45°

• 30°

• 60°

What diameter should the pipe be taken as far as possible before reducing to 15mm for a gravity-fed shower installation?

• 15mm

• 22mm

• 25mm
