Product details

Pentair 500146 is the 8 inch StarGuard main drain cover with a short ring, finished in dark gray and sold as a 2 pack. It is built for residential inground pool and spa installations.

Compliance

StarGuard main drains comply with provisions of the ANSI per ASME A112.19.8-2007 standard and the Virginia Graeme Baker Pool and Spa Safety Act. Drain covers carry a service life set by the manufacturer and by local rules, which is one reason they are normally replaced in pairs rather than one at a time.

Flow

The grate gives 15.35 sq-in of open area, an industry leading figure for a cover this size. In areas where water velocity through the grate is capped at 1.5 ft per sec, that open area supports flow rates up to 72 gpm.

Choosing the right one

StarGuard covers are made in several colors and configurations. This listing is the 8 inch dark gray cover with the short ring, so check the size, the color and the ring length against what is in the pool before ordering.
