## Abstract

A plumbing fixture includes a plumbing fixture body having a composition of, by weight percentage, 58-63 of copper, 0.8-1.5 of bismuth, 0.05-0.15 of phosphorous, and a remainder of zinc and any impurities. The plumbing fixture body includes a first opening and a second opening that are arranged to communicate a fluid there through. The first opening defines a first inner diameter D1 and the second opening defines a second inner diameter D2 such that a ratio of D1/D2 is 1.05-2.3.

## Claims

### Claim 1

A plumbing fixture comprising:
a plumbing fixture body including a composition by weight percentage of:
58-63 of copper,
0.8-1.5 of bismuth,
0.05-0.15 of phosphorous, and
a remainder of zinc and any impurities,
the plumbing fixture body including a first opening and a second opening arranged to communicate a fluid there through, the first opening defining a first inner diameter D1 and the second opening defining a second inner diameter D2 such that a ratio of D1/D2 (D1 divided by D2) is 1.05-2.3.

### Claim 2 (depends on 1)

The plumbing fixture as recited in claim 1, wherein at least one of the first opening or the second opening has a threaded outer diameter.

### Claim 3 (depends on 1)

The plumbing fixture as recited in claim 1, wherein at least one of the first opening or the second opening has a threaded inner diameter.

### Claim 4 (depends on 1)

The plumbing fixture as recited in claim 1, including a valve member within the plumbing fixture body, the valve member being operable to control communication of fluid between the first opening the second opening.

### Claim 5 (depends on 1)

The plumbing fixture as recited in claim 1, wherein the ratio is 1.1-2.1.

### Claim 6 (depends on 5)

The plumbing fixture as recited in claim 5, wherein the ratio is 1.62-1.65.

### Claim 7 (depends on 1)

The plumbing fixture as recited in claim 1, wherein the ratio is 1.05-1.6.

### Claim 8 (depends on 7)

The plumbing fixture as recited in claim 7, wherein the ratio is 1.08-1.10.

### Claim 9 (depends on 1)

The plumbing fixture as recited in claim 1, wherein the first opening and the second opening are non-coaxially arranged.

### Claim 10 (depends on 1)

The plumbing fixture as recited in claim 1, wherein the first opening and the second opening are coaxially arranged.

### Claim 11 (depends on 1)

The plumbing fixture as recited in claim 1, wherein the plumbing fixture body includes a third opening having a valve actuator located therein.

### Claim 12 (depends on 11)

The plumbing fixture as recited in claim 11, wherein the third opening is coaxially arranged with the first opening and non-coaxially arranged with the second opening.

### Claim 13 (depends on 11)

The plumbing fixture as recited in claim 11, wherein the third opening defines an inner diameter D3 that is non-equivalent to the first inner diameter D1 and the second inner diameter D2.
