## Abstract

A pipe stub is provided that includes an elongated cylindrical portion that is selectively sealed on one end. For example, the cylindrical portion may be selectively sealed with a removable diaphragm. In operation, after the pipe stub is interconnected to a plumbing system and a leak test is completed, the plumber severs show otherwise circumvents the diaphragm to open the pipe stub, which can be used to receive additional plumbing components.

## Claims

### Claim 1

A member for interconnection to a fluid delivery or fluid waste system, comprising:
a cylindrical pipe stub having a first end and a second end, said first end being adapted for interconnection to the fluid delivery or fluid waste system; and
a diaphragm associated with said second end of said pipe stub.

### Claim 2 (depends on 1)

The member of claim 1, wherein said pipe stub has a plurality of spaced notches extending about the outer periphery thereof

### Claim 3 (depends on 1)

The member of claim 1, wherein said pipe stub has a plurality of spaced notches extending about the inner periphery thereof

### Claim 4 (depends on 1)

The member of claim 1, wherein said pipe stub has a plurality of spaced notches extending about the outer periphery thereof and a plurality of notches extending about the inner periphery thereof

### Claim 5 (depends on 1)

The member of claim 1, wherein said first end of said pipe stub is adapted to be inserted into a tee of the fluid delivery or fluid waste system.

### Claim 6

A member for interconnection to a fluid delivery or fluid waste system, comprising:
a pipe stub having a first end and a second end, said first end being adapted for interconnection to the fluid delivery or fluid waste system; and
a closure member associated with said second end of said pipe stub.

### Claim 7 (depends on 6)

The device of claim 6 wherein said closure member is a diaphragm.

### Claim 8 (depends on 6)

The device of claim 6 wherein said closure member is a outwardly extending wall.

### Claim 9 (depends on 6)

The device of claim 6 wherein said closure member is an inwardly extending wall.

### Claim 10 (depends on 6)

The device of claim 6 wherein said closure member is a wall that is spaced from said second end of said pipe stub.

### Claim 11 (depends on 10)

The device of claim 10 wherein said wall has an outer edge that is selectively interconnected to an inner surface of said pipe stub.

### Claim 12 (depends on 6)

The device of claim 6 wherein said closure member is a cap that operably engages threads incorporated into the outer surface of said pipe stub.

### Claim 13 (depends on 6)

The device of claim 6 wherein said closure member is a wall that is selectively interconnected to said second end of said pipe stub by a thinned wall portion.

### Claim 14 (depends on 6)

The device of claim 6, wherein said pipe stub has a plurality of notches extending about the outer periphery thereof.

### Claim 15 (depends on 6)

The device of claim 6, wherein said pipe stub has a plurality of notches extending about the inner periphery thereof.

### Claim 16 (depends on 6)

The device of claim 6, wherein said pipe stub has a plurality of outer notches extending around the outer periphery thereof and a plurality of inner notches extending around the inner periphery thereof.

### Claim 17

A method of selectively blocking fluid flow through a fluid delivery or fluid waste system, comprising:
providing a hollow pipe stub adapter having a first length defined by a first end and a second end, said second end having a closure member associated therewith;
interconnecting said first end of said pipe stub to a first opening in the fluid delivery or fluid waste system;
performing a first leak test of the fluid delivery or fluid waste system;
cutting said pipe stub to create a second pipe stub of a second length;
interconnecting said second pipe stub to a second opening in the fluid delivery or fluid waste system;
performing a second leak test of the fluid delivery or fluid waste system; and
cutting said pipe stub to create a third pipe stub of a third length.

### Claim 18 (depends on 17)

The method of claim 17 wherein said pipe stub includes a plurality of notches about the outer perimeter thereof that facilitates cutting of said pipes stub.

### Claim 19 (depends on 18)

The method of claim 18 wherein said closure member is a diaphragm, and further comprising:
interconnecting said third pipe stub to a third opening in the fluid delivery or fluid waste system;
performing a third leak test of the fluid delivery or fluid waste system; and
severing said diaphragm.
