Abstract
The present invention is a sewage system isolation valve assembly designed to be installed between a sewage drainage line of a building and a sewage service line. In its initially closed position, the isolation valve assembly provides a closure means for closing and isolating the operating sewage system of the building, thereby permitting the drainage system of the building to be filled with water for testing purposes. Once the testing procedures are complete, a test shut-off baffle may be torn or detached from a gasket which is securely attached or secured within the sewer drainage system. The test shut-off baffle is removed from the isolation valve assembly by pulling on a removal means.
Claims18
A sewage system isolation valve assembly for isolating a fluid outlet of a sewage line of a building from a sewage service line, comprising the combination of:
- (a) a test shut-off baffle removably sealed within said sewage line, said test shut-off baffle forming a closure of said fluid outlet;
- and
- (b) removal means for disconnecting and for removing said test shut-off baffle from said sewage line, said removal means having a first end connected to said test shut-off baffle, said removal means having a second end;
- and
- (c) a float attached to said second end, said float and second end may enter an access port of said sewage line whereby pulling of said second end disconnects said test shut-off baffle from said sewage line.
A sewage system isolation valve assembly for isolating a sewage line of a building from a sewage service line, comprising the combination of:
- (a) gasket being appropriately shaped and dimensioned to be located in an interior of said sewage line, said gasket having an outer wall and an inner circumference, said gasket being securely engaged in fluid-tight engagement with said sewage line, said sewage line having a fluid outlet communicating with said sewage service line, said gasket being positioned near said fluid outlet;
- (b) a test shut-off baffle being shaped and dimensioned to seal an area of said gasket defined by said inner circumference, said test shut-off baffle and said gasket forming a closure of said fluid outlet of said sewage line;
- (c) removal means for disconnecting said test shut-off baffle from said gasket and for removing said test shut-off baffle from said sewage line, said removal means having a first end and a second end, said first end being connected to said test shut-off baffle, wherein pulling of said second end of said removal means causes said test shut-off baffle to be disconnected from said gasket;
- and,
- (d) a float attached to said second end of said removal means, said float causing said second end of said removal means to rise into an access port of said sewage line.
