## Abstract

A water trap for use in connection with a wash basin or other plumbing fixture includes a housing, an inlet extending into the housing and an outlet extending out of the housing. The water trap also includes a weir inside the housing between the inlet and the outlet, and a trap chamber defined by the space within the housing on an upstream side of the weir. The trap chamber is designed to retain liquid following a drain cycle from the wash basin or other plumbing fixture.

## Claims

### Claim 1

A water trap for use in connection with a wash basin or other plumbing fixture, the water trap comprising:
a housing;
an inlet extending into the housing;
an outlet extending out of the housing;
a weir inside the housing between the inlet and the outlet; and
a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the wash basin or other plumbing fixture.

### Claim 2 (depends on 1)

The water trap of claim 1, wherein the inlet includes a discharge end that is configured to be submerged within the liquid retained within the trap chamber.

### Claim 3 (depends on 1)

The water trap of claim 1, further comprising:
a cleanout port that provides access to the trap chamber; and
a removable plug connected to the cleanout port.

### Claim 4 (depends on 1)

The water trap of claim 1, wherein the housing comprises:
a top;
a bottom;
a plurality of side walls; and
a plurality of end walls.

### Claim 5 (depends on 4)

The water trap of claim 4, wherein the inlet includes a discharge end that is spaced above the bottom of the housing at a first height (h1); and wherein the weir extends upward from the bottom of the housing to a second height (h2).

### Claim 6 (depends on 5)

The water trap of claim 5, wherein the second height (h2) is greater than the first height (h1), such that the discharge end of the inlet is located closer to the bottom of the housing than an upper portion of the weir.

### Claim 7 (depends on 6)

The water trap of claim 6, wherein the outlet is a dual-sided outlet that includes a pair of discharge ports aligned along a lateral axis that is substantially orthogonal to a longitudinal axis extending between the plurality of end walls.

### Claim 8 (depends on 4)

The water trap of claim 4, further comprising:
an inlet baffle extending downward from the top of the housing into the trap chamber; and
an air pocket between the inlet baffle and the inlet, wherein the air pocket contains pressurized air during use.

### Claim 9 (depends on 1)

The water trap of claim 1, wherein the housing includes a funnel section proximate to the outlet and downstream from the weir.

### Claim 10 (depends on 1)

The water trap of claim 1, wherein the inlet is substantially vertical and the outlet is substantially horizontal.

### Claim 11

A water trap for use in connection with a floor drain, the water trap comprising:
a housing;
an exterior grate on the top of the housing;
a deflector plate under the exterior grate;
an inlet baffle connected to a distal end of the deflector plate;
an intake channel between the inlet baffle and the housing;
an outlet extending from the housing;
a weir inside the housing between the inlet baffle and the outlet; and
a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the floor drain.

### Claim 12 (depends on 11)

The water trap of claim 11, wherein a lower end of the inlet baffle is configured to be submerged within the liquid retained within the trap chamber.

### Claim 13 (depends on 11)

The water trap of claim 11, wherein the housing includes a bottom, a plurality of ends and a plurality of sides.

### Claim 14 (depends on 13)

The water trap of claim 13, wherein the lower end of the inlet baffle is spaced above the bottom of the housing by a first height (h1).

### Claim 15 (depends on 14)

The water trap of claim 14, wherein the weir extends above the bottom of the housing by a second height (h2) that is greater than the first height (h1).

### Claim 16 (depends on 11)

The water trap of claim 11, wherein the deflector plate is removable to provide access to the trap chamber located under the deflector plate.

### Claim 17 (depends on 11)

The water trap of claim 11, wherein the deflector plate is hinged to permit the deflector plate to be opened to provide access to the trap chamber located under the deflector plate.

### Claim 18

A water trap for use in connection with an integrated wash basin, the water trap comprising:
a housing;
a deflector plate on top of the housing;
an inlet baffle connected to a distal end of the deflector plate;
an intake channel between the inlet baffle and an end wall of the housing;
an outlet extending from the housing;
a weir inside the housing between the inlet baffle and the outlet; and
a trap chamber defined by the space within the housing on an upstream side of the weir, wherein the trap chamber is designed to retain liquid following a drain cycle from the integrated wash basin.

### Claim 19 (depends on 18)

The water trap of claim 18, wherein the outlet extends horizontally away from the housing.

### Claim 20 (depends on 18)

The water trap of claim 18, further comprising:
a cleanout port that provides access to the trap chamber; and
a removable plug connected to the cleanout port.
