VGB Main Drain Replacement
& Compliance Certification
Protect your commercial facility from immediate LA County health closure and catastrophic entrapment liability. Certified ANSI/APSP-16 drain replacement without draining your pool.
Federal VGB Compliance & Suction Safety
Under California Health and Safety Code Section 116064.2, operating a commercial pool with missing, broken, or expired drain covers is an immediate Class 1 health shutdown violation.
5-Year VGB Drain Cover Replacement
All commercial pool and spa suction outlet fitting assemblies (SOFA) have strict 5-year expiration dates stamped by the manufacturer. We supply and install ANSI/APSP-16 certified replacement covers.
Certified Hydraulic Flow Rate Calculations
We calculate maximum pump flow capacity (GPM) vs. rated grate flow velocity to ensure your dual-drain system or unblockable 18"x36" channel grate cannot entrap a bather.
LA County DPH Compliance Documentation
We generate official VGB compliance verification packets complete with model numbers, flow ratings, date of installation, and technician CSLB credentials ready for your health inspection binder.
Submerged Underwater Diver Installation
In most cases, we can replace submerged suction grates and brass screw anchors using specialized commercial diving gear without draining 50,000+ gallons of heated commercial pool water.
Safety Vacuum Release System (SVRS) Testing
Testing and calibration of mechanical and electronic SVRS vacuum break devices (such as Vacless, Stingl, and IntelliFlo SVRS) on single-suction drain applications.
Sump Depth & Mud Ring Structural Inspections
We inspect the concrete sump depth beneath the grate to confirm minimum 1.5x pipe diameter clearance, preventing localized high-velocity suction entrapment points.
