Vacuum Breaker 3/4 in PVC Viton

This Hayward Flow Control vacuum breaker prevents back-siphonage in pool and spa plumbing systems. It installs on a 3/4 inch FNPT threaded connection and uses a PVC body with a Viton seal. The unit is rated for 150 psi maximum pressure and a 140 Degrees F temperature range.

Suits pool equipment needing anti-siphon protection

Installers protecting pool pumps, heaters or chemical feeders from reverse flow will find this device appropriate. It is not intended for potable water lines or high-temperature hydronic systems that exceed the stated temperature limit. Buyers requiring a larger connection size or a different seal material should look elsewhere.

Simple threaded installation on 3/4 inch FNPT

The breaker screws directly onto the female pipe thread without special tools. Ensure the Viton seal seats cleanly and do not exceed the 150 psi pressure rating. Over-tightening can crack the PVC body, and debris in the line may prevent the internal float from sealing properly.

Questions about this item

Will this 3/4 in FNPT vacuum breaker thread directly onto my existing 3/4 in male pipe threads?

Yes, the 3/4 in FNPT connection mates with standard 3/4 in male NPT threads on your existing piping.

Can the PVC body and Viton seal handle 140 °F water alongside my older metal fittings?

The PVC body and Viton seal are rated for 140 °F and 150 psi, compatible with typical metal plumbing at those conditions.

How do I confirm the breaker is venting correctly after installation?

Run water through the line; the internal float should rise to seal under flow and drop to vent atmosphere when flow stops, preventing backsiphonage.
