摘要:
The present invention relates to a rough-in box used during the construction of buildings having poured concrete flooring, such as multi-story high-rise buildings. The rough-in box may be used to retain an opening in the floor through which plumbing and mechanical components may be installed after concrete has been poured around the device and hardens into a slab. The present invention also relates to a method comprising the steps of assembling the side walls of a box, placing a lid made of a material stronger than that of the side walls and capable of supporting a weight of 2,000 pounds, placing the box over a hole on the floor, and pouring concrete to form a floor around the box. The box will remain in place providing an accessible penetration through the flooring with space for plumbing connections and a flush surface with the floor over which pallet jacks and workers may travel without obstruction.

A vacuum fluid transfer system transfers a fluid by setting inside of a main pipe line (10) to vacuum and using a pressure difference. The system includes a portion where the main pipe line (10) is horizontally arranged, and is provided with an automatic intake valve (17) and a terminal automatic intake valve (16) for introducing atmosphere into the main pipe line (10) from the outside of the main pipe line (10) when a degree of vacuum inside the main pipe line (10) is reduced to a predetermined value or lower.

An apparatus for preventing waterlogging of the sensor and controller valves used to regulate operation of the vacuum interface valve in a sump vented vacuum sewerage system. A float valve operates in accordance with the sewage level in a sump pit and communicates atmospheric pressure to the sensor and controller valves while the sewage level is below a predetermined limit, but closes passage of sewage therethrough once the sewage level exceeds the predetermined limit. A pressure-relief valve may also be operatively connected to the float valve that vents excessive hydrostatic pressure buildups in the sump pit to the atmosphere.
