Vortex Cover Compatibility
Yes, a Vortex-style anti-entrapment grate cover (19-1/2" x 5") can be used on a single main drain for a hotel pool, provided it meets VGBA (Virginia Graeme Baker Act) standards for anti-entrapment drain covers. The elongated rectangular shape fits many commercial single-drain setups where flow velocity stays below the maximum allowed (typically 1.5 ft/sec for that grate size). Confirm the exact model is ASME/ANSI A112.19.8 certified and sized to fully cover your drain sump.
SVRS-10 Requirement in California
Yes, you need the SVRS-10 (or equivalent Safety Vacuum Release System) for a single main drain on a California public/hotel pool. Under California Health & Safety Code Section 115929 (Public Pool and Spa Safety Act, tied to AB 1020), all public pools with a single main drain must have both:
This applies regardless of pool size since 2018—no grandfathering for single-drain systems in commercial/public settings. Local county health inspectors (e.g., LA County, Orange County) enforce this strictly during permitting and annual inspections.

Yes, you need the SVRS-10 (or equivalent Safety Vacuum Release System) for a single main drain on a California public/hotel pool. Under California Health & Safety Code Section 115929 (Public Pool and Spa Safety Act, tied to AB 1020), all public pools with a single main drain must have both:
- A VGBA-compliant anti-entrapment drain cover, and
- A secondary anti-entrapment system like SVRS, SVRS-10, or reverse flow/SFS (Safety Flow Switch).
This applies regardless of pool size since 2018—no grandfathering for single-drain systems in commercial/public settings. Local county health inspectors (e.g., LA County, Orange County) enforce this strictly during permitting and annual inspections.
Recommended Setup
- Drain cover: Vortex or equivalent VGBA-certified grate (19-1/2" x 5").
- Backup: Hayward/Paramount SVRS-10 installed inline on the suction line.
- Permit note: Submit both to your county health department for pre-approval to avoid failed inspections.
