What are the differences between the two hydrant models?

The benefits of the V1 model:

Round faceplate.
Simpler design, lower cost.
Smaller footprint. The round faceplate has a smaller footprint and uses a round entry hole. In certain situations, especially in retrofits, a circular wall opening can be a much easier option. The V1 also has a slimmer profile and is better suited for hidden installations or sites where space is an issue.
Better for rigid plumbing. We recommend using PEX to connect to your House Hydrant, even if the rest of the home is plumbed with copper. PEX provides better freeze protection and adding an expansion loop inside the wall allows for easy maintenance from the exterior of the building (see install guide for more details). If you want to attach the House Hydrant to a rigid copper pipe, the V1 model’s round faceplate can rotated out from the exterior of the building. V2 models attached to rigid pipe will require access to the plumbing from the interior.
Basic backflow protection. Every Aquor hose connector has an integrated one-way check valve to prevent backflow. In clean water applications where cross-contamination of liquids is not a hazard, backflow prevention may not be a concern.

The benefits of the V2 model:

Integrated atmospheric vacuum breaker. The built-in vacuum breaker is located below the outlet and does not reduce flow. This patent-pending design provides higher reliability, better flow rates, and won’t spray water on the user.
Two layers of backflow protection. In the event of backflow, the vacuum breaker introduces air into the outlet, relieving pressure. Along with the one-way check valve in the hose connector, the breaker adds a second layer of anti-siphonage protection.
ASSE certified. The House Hydrant V2 has been independently lab-tested to ASSE 1019-A requirements, the national US standard for frost-free sillcocks as defined by the Uniform Plumbing Code.
