Final answer:
The correct answer is option 4) Sumps for macerating toilets must be equipped with a grinder pump to properly function and manage waste disposal by turning sewage into a fine slurry that can be pumped out.
Step-by-step explanation:
Equipped with a grinder pump. Sumps for macerating toilets are designed to be equipped with a grinder pump, which is essential for macerating or grinding up the sewage into a fine slurry. This slurry can then be easily pumped through a small-diameter pipe to the main sewer line or to a septic system without the need for gravity flow. Macerating toilets are often installed in basements or below the sewer line in a property, and the grinder pump is an integral part of the system that allows for proper function and disposal of waste.
Equipped with a grinder pump. Sumps for macerating toilets are equipped with grinder pumps. These pumps are designed to break down solid waste into smaller particles, allowing for easier and more efficient disposal through the sewage system. By grinding the waste, the macerating toilet can effectively move waste uphill to connect to the main sewer line. This eliminates the need for the sump to be installed below the flood level rim of the fixture and allows for more flexible installation options.
