It depends on where your sewers are located; wastewater needs to be collected in one place, so it is determined based on the layout of the equipment on site
#This should be determined based on the layout of the equipment, with the principle of facilitating maintenance in mind#
The vent at the pump inlet is generally used to drain the fluid before maintenance, while the vent at the pump outlet is typically used for exhausting air during pump filling.
When setting up sewage outlets, considerations should include ease of operation, convenience for collection, environmental protection and hygiene, as well as compliance with the process requirements. Preferably in front of the pump; if conditions do not permit, it can be placed behind the pump.
I agree with your view. To add something, when the pump is affected by its own structure or a check valve is installed at the outlet, a drain pipe is required to empty the pipeline, and a drain line is also installed for this purpose.
Waste discharge is usually located at the lowest point; the inlet is situated inside the pump, while the outlet is the pipeline behind the check valve
”What does “inside the pump body of the discharge port” mean?
