Low Profile Circular Drain With Water Stop For Swimming Pool

A low profile drain for installation in a surface of a swimming pool or spa formed of a surface material and having a drain inlet, the low profile drain comprising:

• a sump defining an annular chamber and forming a top side defining an annular top opening, the sump forming an outer sidewall and an inner sidewall on opposite sides of the annular top opening, the outer sidewall having an upper peripheral edge about the annular top opening;
• the sump having a water stop extending radially therefrom and adjacent to the upper peripheral edge;
• the sump having an outlet opening formed laterally through one sidewall thereof for communication between the annular chamber and the drain inlet within the surface material when installed, the sump being configured to maintain open communication between the annular top opening and the outlet opening, the annular top opening extending without substantial interruption about a center axis of the sump;
• the top side of the sump defining the annular top opening to be substantially flush with the surface when the low profile drain is installed, and portions of the sump radially inside the inner sidewall and radially outside the outer sidewall being substantially covered by the surface material to blend in with the surface when the low profile drain is installed;
• wherein the water stop includes a horizontal shelf extending radially from the outer sidewall, the water stop being endlessly looped about the outer sidewall.

A sump drain for installation in a surface of a swimming pool or spa formed of a surface material and having a drain inlet, the sump drain comprising:

• a body defining a ring-shaped chamber having an outer sidewall and an inner sidewall on opposite sides of a top opening, the top opening forming a ring;
• the body having an outlet port formed laterally through one sidewall thereof, the ring-shaped chamber in fluid communication through the outlet port with a connection disposed in open communication with the drain inlet;
• the connection configured to extend below the top opening in elevation relative to the surface and having a portion disposed radially inward of the top opening;
• a removable portion defined above the connection;
• and
• at least a first water stop surrounding the top opening, the first water stop extending radially from the body to be embedded within the surface material below the surface;
• wherein the top opening is defined to extend fully without substantial interruption about a center axis of the body, portions of the body defining the top opening remaining substantially flush with the surface when the sump drain is installed in the swimming pool or spa.
