What is one of the benefits of using macerators according to the text?

• They can only be used in urban areas.

• They require access to the main soil stack.

• They offer options for installing sanitary appliances in remote locations.

• They eliminate the need for a gravity WC in the building.

According to Building Regulation part G, what is required if a WC macerator is installed?

• A gravity WC must be installed in a different building.

• No additional plumbing is required.

• A gravity WC must also be located in the same building.

• The main soil stack must be relocated.

Where should washbasins be located in a dwelling?

• In the kitchen only

• In any space which is used for washing up

• In the room containing the closet or in a room or space giving direct access to the room containing the closet

• Outside the dwelling for easy access

What is the required gravity fall for inlet pipes to ensure proper functioning of appliances like macerators?

• 1:30

• 1:40

• 1:50

• 1:60

Why is it important to ensure a sufficient gravity fall from the inlet pipe into appliances such as the Saniflo macerator unit?

• To prevent clogging of the unit with waste

• To allow for easier maintenance

• To prevent soil water from backing up in the shower tray

• To reduce the noise made by the unit

Why is it important to run any vertical outlet pipe as near as possible to the Saniflo macerator unit outlet connection?

• To ensure the optimum discharge capability through the outlet pipework

• To reduce the cost of pipework installation

• To make the installation process faster

• To increase the water pressure in the pipework

How far must the outlet pipework rise vertically before any horizontal pipework is fitted?

• At least 100mm

• At least 200mm

• At least 300mm

• At least 400mm

Which types of pipes are suitable for the discharge pipework of a Saniflo macerator installation?

• Copper pipe only

• Plastic solvent weld pipe only

• Copper pipe or plastic solvent weld pipe

• Any type of plastic pipe

What is advisable to do if a horizontal run of a Saniflo model's 22mm discharge pipe exceeds 10-12 metres?

• Decrease the bore size of the pipework to 20mm

• Keep the bore size the same

• Increase the bore size of the pipework to 32mm

• Replace the pipework with a different material

What type of bends should be used instead of 90° elbows to reduce frictional resistance in copper pipework?

• Knuckle type 90° elbows

• Machine pull bends

• Offset plastic elbows

• Solvent weld pipework
