Do you understand these questions in the selection process of toilet sewage elevator

For many basements, the biggest problem of adding a new toilet may be the problem of sewage discharge. After all, there is no sewer pipe in the basement, which leads to the sewage cannot be discharged by normal gravity flow. In this case, we need to use sewage lifters to solve the drainage problem. Today we will look at some of the more common!!

Question a basement sewage elevator drain pipe connected to the first floor of the sewer pipe, the first floor of the toilet will reverse water?

No. Normally, the floor drain on the first floor will be at least 20CM above the top of the main sewer pipe. Because of the reason of the drop, there will not be the first floor toilet back water. However, in order to ensure that the water seal of all sanitary ware including the floor drain pipe of the toilet on the first floor is not damaged, some points need to be paid attention to when the pressure drain pipe is connected to the main sewage pipe on the first floor:

(1) The pressure drain pipe of the sewage elevator must be connected from above the main sewage pipe on the first floor (it is prohibited to connect with the φ50mm sewer branch pipe of the sanitary ware on the first floor, including the floor drain)

② If the φ110mm pressure drain pipe, the connection point with the main sewage pipe on the first floor should be as close as possible to the end of the main sewage pipe and at least 1.5m away from the φ50mm branch pipe of the nearest sanitary appliance

(3) When the pressure drain pipe is connected to the main sewage pipe of the first floor, it is recommended to use the oblique tee, and the discharge direction of the pressure drain pipe is consistent with the direction of the sewage discharge room.

Question two sewage elevator and floor drain water how to connect?

If there is a shower room in the basement, the shower needs to be separately raised. The height of the elevation shall be at least 20CM from the floor drain of the shower room to the bottom of the machine. The sewer pipe of the shower room shall be equipped with a water trap, and the sewer pipe of the shower room shall be installed with a 1% slope to the entrance of the machine. If you have to install a bathroom drain. It means that the sewage elevator should be installed in the pit lower than the completion surface of the toilet. If it is installed in the pit, the sewage elevator should be kept dry and ventilated, and there should be no other accidental water flowing into the pit, such as cleaning and sanitation, and the elevator should not be submerged in the water.

Question three sewage elevator is fully automatic, need I manual operation?

Sewage elevator is automatic start and stop, when the sewage in the box reaches a certain amount, the machine senses the liquid level, the motor automatically starts to work and drain, when the liquid level is reduced to a certain position, the motor automatically stops, the whole process does not need you to manually operate the machine.
