Vac-Alert VA-2000S Safety Vacuum Release System (SVRS) – Submerged Suction Applications
The Vac-Alert VA-2000S is a Safety Vacuum Release System (SVRS) designed for submerged suction installations—meaning the circulating pump suction is below the pool water surface. If a suction entrapment condition occurs, the VA-2000S is engineered to release vacuum quickly by introducing air into the suction line, helping reduce the dangerous suction force at the drain or suction outlet.
Key Features
- For submerged suction systems: intended for installations where the pump is below the water level
- Passive, non-electrical design: no wiring required
- No manual reset required after activation (system behavior depends on plumbing/pump conditions)
- Designed to react rapidly to abnormal vacuum conditions to help reduce entrapment risk
- Chemical-resistant construction for pool and spa environments
How It Works (Overview)
- Under normal operation, the device remains sealed within the suction plumbing.
- During a sudden high-vacuum event (such as entrapment), the unit is designed to open and admit air into the line,helping break the vacuum and reduce suction at the outlet.
Application & Selection Notes
- VA-2000S: submerged suction (pump below water surface)
- If your pump is at or above the water level, you typically need the suction-lift version instead (different model).
- Always verify local code requirements and confirm your plumbing layout supports SVRS installation.
Technical Highlights
- Model: VA-2000S
- Type: Safety Vacuum Release System (SVRS)
- Submerged-suction design details: incorporates an orifice opening below the surge tube section and an internalcheck valve assembly configured to help prevent water migration into the unit under positive hydrostatic head conditions
Installation Notes
- Install only in accordance with the manufacturer’s instructions and applicable codes.
- Placement, orientation, and pipe sizing matter—SVRS performance depends on correct installation.
- After installation, test system operation per the manufacturer’s procedure before placing the pool/spa back into service.

Maintenance Tips
- Keep baskets and filters clean—restricted flow can increase vacuum conditions and stress suction plumbing.
- Inspect suction outlet covers regularly and replace cracked or loose covers immediately.
- During routine equipment checks, inspect the SVRS installation area for leaks, cracks, or physical damage.
- If the system experiences unusual suction behavior, shut down circulation and have the equipment evaluated before continued operation.
