This 12 inch Hayward square main drain replacement cover is a high flow cover and has an inner only (no outer frame). Hayward’s High Flow covers have some of the industry’s highest ASME approved flow rates. Each size and flow design cover retrofit to existing Hayward frames and are designed for an extensive 7 year life span. All Hayward WG Series suction outlets and replacement covers are VGB compliant and are tested to ASME A112 19.8b-2009 and ANSI/APSP-16 standards as well as meeting CPSC requirements.
Hayward heavy-duty grates are injection molded with ABS which resists chemical attack that leads to yellowing. For concrete, vinyl, or fiberglass pools, they are totally noncorrosive and nonconductive.
For residential and commercial concrete pools, Hayward square drain covers are available in a wide range of sizes and flow designs to satisfy any installation requirement. Whether the application demands frames and covers for new construction or replacement cover assemblies for existing installations, Hayward suction outlets set the standard for quality and value.
Installation of anything other than the recommended Hayward drain cover on a Hayward frame or Hayward sump may not be ASME A112 19.8b-2009 and ANSI/APSP-16 compliant. Likewise, the installation of a Hayward drain cover on a non-Hayward frame may not be compliant.
