Low profile circular drain with water stop for swimming pools

A sump drain for connecting to a filtering system and installation in a plaster floor of a swimming pool or spa comprising:

• a chamber disposed about a central hub displaced radially inward therefrom to be embedded in the plaster floor, the chamber having an inner sidewall and an outer sidewall defining a contiguous annular top opening therebetween, the chamber being formed with a gutter formed on the outer sidewall for embedded anchoring in the plaster floor;
• the contiguous annular top opening of the chamber being in open communication with the central hub through a plurality of ports defined therebetween for tying into the filtering system;
• the sump drain configured such that when installed, plaster substantially fills a space between the chamber and the central hub;
• and
• the sump drain further configured such that when installed, the contiguous annular top opening is substantially flush with the plaster floor.

A sump drain for connecting to a filtering system and installation in a plaster floor of a swimming pool or spa comprising:

• a chamber having an inner sidewall, an outer sidewall, and a contiguous annular top opening between the sidewalls, the chamber being formed with a gutter formed on the outer sidewall for embedded anchoring in the plaster floor;
• the chamber further having conduits extending radially inward from the inner sidewall to an inlet of the filtering system, the inlet being radially displaced from the chamber to be embedded in the plaster floor;
• and
• the sump drain further configured such that when installed the contiguous annular top opening is substantially flush with the pool or spa floor.

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

• an annular chamber for embedding in the surface;
• the annular chamber having a contiguous annular top opening defined between inner and outer sidewall portions covered by a removable circular grid cover;
• a central hub displaced radially inward from and in open communication with the annular chamber, the central hub being embedded in the surface of the swimming pool or spa and coupled to the drain inlet;
• the annular chamber radially centered around the central hub, the annular chamber being formed with a gutter formed on the outer sidewall portion for embedded anchoring in the surface of the swimming pool or spa;
• a removable cap above the central hub for accessing the drain inlet;
• and
• wherein the removable circular grid cover encircles the removable cap substantially flush with the surface when installed.

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

• an annular chamber having a contiguous annular top opening defined between inner and outer sidewall portions, the drain inlet being embedded in the surface of the swimming pool or spa;
• a ring shaped grid cover covering the contiguous annular top opening;
• the annular chamber being in open communication with the ring shaped grid cover and the drain inlet, the chamber being formed with a gutter formed on the outer sidewall portion for embedded anchoring in the surface of the swimming pool or spa;
• and
• a removable cap surrounded by the ring shaped grid cover, the removable cap disposed above the drain inlet.
