Vacless Automatic SVRS Adjustable, Auto-Reset, Center Thread In stock$45316
Quick overview
- Releases entrapment fast A high vacuum event moves the seal in milliseconds, letting outside air fill the pump pot so the pump loses prime and the suction lets go.
- Adjustable model The adjustable version compensates for piping runs that a fixed unit cannot, which is what makes it suitable for unusual layouts.
- Automatic reset Once the entrapment clears, the spring loaded seal returns to its normal operating position on its own for re-priming.
- Center thread Installs by removing the suction side drain plug on the pump and threading the valve into its place.
- Half to ten horsepower Rated for 0.5 to 10.0 horsepower pumps across hot tubs, spas, fountains, wading pools and residential or commercial pools.
- Surge suppressor and drain aid It also arrests sudden vacuum spikes at pump start up, and removing it lets the pump drain fully for winter.

Product details
The Vacless SVRS-10ADJ is an adjustable safety vacuum release system with automatic reset and a center thread connection. It threads into the pump in place of the suction side drain plug and covers pumps from 0.5 to 10.0 horsepower.
How it works
Centrifugal pool pumps pull a strong vacuum at the inlet. If something blocks the suction side, that vacuum climbs sharply. The valve uses an orthogonal seal, an o-ring on a moving disc that seals on both the face and the radius, held closed by a spring. When the vacuum spikes, the disc moves, the o-ring crosses air channels, and atmospheric air rushes into the pump pot. The pump loses prime and the suction releases. The seal then springs back to its normal position so the pump can re-prime.
Why the adjustable model
Pool plumbing is rarely textbook. The adjustable version compensates pneumatically for variations in the piping and filtration system, so it can provide suction relief on runs where a fixed unit would be a poor match. Vacless states the design is compliance tested up to 200 feet.
Two jobs beyond safety
The same seal movement suppresses surges. It absorbs the vacuum spike at start up, which spares the pump and filter the shock and vibration that shorten equipment life. And because the valve threads out, removing it lets water drain fully from the pump for winterization.
