Abstract

A channel drain with a water stop is adapted for handling pool water in a swimming pool having a plastered surface. The channel drain, preferably a sump drain includes an elongated channel having a drain port and an opening for receiving pool water. A water stop abutting and substantially encircling the opening is formed into a trough for retaining and collecting the pool water. The drain is configured for installation in a pool with the water stop buried in the plastered surface, such that pool water seeping between the opening and the plaster is trapped by the trough, preventing the pool water from intruding beyond the plastered surface.

Claims

1. A sump drain for handling pool water in a swimming pool having a plastered surface, comprising:

an elongated channel having a drain port and an opening for receiving the pool water;

a water stop abutting and substantially encircling the opening;

the water stop comprising a trough for retaining and collecting the pool water; and

wherein the sump drain is configured for installation in the pool with the water stop buried in the plastered surface, such that the pool water seeping between the opening and the plastered surface is trapped by the trough, thereby preventing the pool water from intruding beyond the plastered surface.

2. The sump drain of claim 1 wherein the elongated channel has multiple drain ports.

3. The sump drain of claim 1 wherein the trough includes a substantially horizontal member extending from the elongated channel, and a substantially vertical member extending upwardly from the horizontal member.

4. The sump drain of claim 1 wherein the opening includes a rim extending upwardly from the elongated channel.

5. The sump drain of claim 4 wherein the trough is disposed below the rim.

6. An improved non-blockable sump drain for a plastered swimming pool, comprising:

a channel having an opening and a rim;

a trough substantially surrounding and abutting the opening, the trough disposed below and outboard the rim;

wherein when the sump drain is configured to be installed in the swimming pool with plaster surrounding the opening, the trough also being covered by plaster such that only the opening is visible;

whereby upon installation pool water s prevented from seeping between the drain and the surrounding plaster.

7. A method of preventing pool water from intruding into a supporting wall in a plastered pool adjacent a pool drain comprising the steps of:

providing a drain with an opening for receiving the pool water;

abutting a trough to the opening;

securing the drain to the supporting wall; and

substantially surrounding the drain and the trough with plaster;

whereby the pool water is unable to seep between the pool drain and the surrounding plaster.
