A hybrid flushing system for water free urinals is presented with a housing having a wall portion forming a cavity for receiving a cartridge. The housing also includes a flushing fluid inlet portion for receiving a flushing fluid and a flushing fluid directing portion configured to direct the flushing fluid. A cartridge for installation into a housing is presented, including a cartridge wall, a flushing fluid receiving portion and a flushing fluid directing portion to direct flushing fluid received to any portion to clean areas of the housing, the cartridge, and connected plumbing. Steps for cleaning a hybrid flushing system are presented with an act of directing a flushing fluid into an area, where the area is one of a cartridge for a hybrid flushing system, a housing for a hybrid flushing system, and a plumbing system connected with the hybrid flushing system.

The invention relates to a buffer box of a vacuum drainage system, which vacuum drainage system comprises the buffer box, which buffer box comprises as an outer frame structure side walls, end walls, a top wall and a bottom wall and which buffer box further comprises at least one inlet and an outlet, a vacuum drainage piping, at least one collection branch connected to the vacuum drainage system and to the outlet of the buffer box, wherein each of the collection branches comprises a suction valve, a pump connected to the vacuum drainage piping and configured to create negative pressure in the vacuum drainage piping. The buffer box comprises at least two compartments, which comprise a main compartment and a suction compartment with a suction outlet. Between the main compartment and the suction compartment a baffle is located. The baffle extends from the top wall towards the bottom wall and is located at a distance from the bottom wall such that a baffle opening is formed between the main compartment and the suction compartment. The baffle is configured to prevent the air on top of the liquid in the main compartment to enter the suction compartment.

Disclosed is a basement sewer drain pump housing that draws fluid from a drain into a housing, where after the fluid is discharged from the housing and out of the basement. The device comprises a pickup tube having a fluid level sensor, which is placed within a sewer main drain or floor drain. The housing comprises an enclosed volume, a suction tube connected to the pickup tube, a suction pump, and a discharge pump. The pump is activated by a switch controlled by the pickup tube fluid sensor, the fluid is drawn into the housing from the drain and discharged through a discharge pipe. The device operates from outlet or battery and serves as a basement drain pump that prevents fluid and sewage backflow during power outages and plumbing blockages. Another modification provides two donuts to prevent the flow of fluid locking both the floor drain and the main sewer drain. Another embodiment show an inflator to stop the flow of fluids.

The invention is a device which uses stored pressure to pump waste and a corresponding method of use. Waste is stored in a first chamber and the chamber is subsequently sealed by a valve and pressurized prior to a second valve opening. The pressurized waste is thereby ejected from the pressure chamber down an outlet pipe.

This pump includes a computing device, with a vibration waveform analysis section and a memory, the analysis section being designed to control the motor, by comparing a vibration waveform received from the vibration sensor with vibration waveforms saved in the memory.
