Aqualine HEVB Hose Bib Vacuum Breaker 3/4 Inch Brass

Product Description

The AQUALINE HEVB is a brass hose bib vacuum breaker (HVB) designed to prevent backflow and protect potable water supplies at outdoor hose connections. It installs between a hose bib and a garden hose, creating a compliant atmospheric vacuum break that stops non-potable water or chemicals from siphoning back into the supply line. The 3/4 inch male hose thread (MHT) inlet connects directly to the hose bib spigot, while the 3/4 inch female hose thread (FHT) outlet accepts a standard garden hose. All-brass construction provides durability and corrosion resistance in outdoor service.

This vacuum breaker is suited for residential and light commercial applications wherever a hose bib is used near irrigation equipment, chemical injectors, or other potential contamination sources. Typical installation locations include exterior wall faucets, utility sink faucets, and landscape hose stations. Plumbers and irrigation contractors install this device to bring hose bib assemblies into compliance with plumbing codes that require backflow protection at hose thread connections.

Installation Notes

A licensed plumber or qualified irrigation technician should install this device in accordance with local plumbing codes and the International Plumbing Code (IPC) backflow prevention requirements. Shut off water supply to the hose bib before installation. Hand-tighten the vacuum breaker onto the hose bib spigot, then snug with pliers using a rag to protect the finish — do not overtighten brass fittings. Verify the device is oriented correctly and that the vent port faces downward per manufacturer guidance to allow proper atmospheric venting.
