The Watts LF288A is a lead-free anti-siphon vacuum breaker designed to prevent the reverse flow of polluted water into potable water supplies due to backsiphonage. Ideal for low-flow, non-continuous hot or cold water applications, such as laboratory equipment, it features a full-size orifice to ensure maximum flow capacity. Constructed with a lead-free brass body and a chemical-resistant silicone seat disc, it offers durability and tight seating. The vacuum breaker includes a chrome-plated hood and an atmospheric vent to prevent spilling under all rates of flow.
