Product Overview
The Apollo 4A Series reduced pressure principle backflow preventer helps protect potable water systems from both backsiphonage and backpressure in approved high-hazard applications. The assembly uses two check modules and a relief valve to help separate the potable supply from non-potable water when a backflow condition occurs.

FAQ
What is the benefit of an RPZ assembly?
An RPZ assembly provides protection against backsiphonage and backpressure and includes a relief valve that can discharge water if conditions require it.
Does this assembly include shut-off valves?
Yes. The A2F assembly configuration includes the reduced pressure assembly with shut-off valves and test cocks.
What should I check before ordering?
Confirm size, connection type, orientation, local approval requirements, drainage needs, and whether an RPZ is required for the hazard level.
